This release brings performance improvements, a major CLI update, new features for managing data
connections, and a large number of bug fixes and stability improvements.

🎯 A special thanks to @antonkesy and @wuuer for their contributions in this release.

What's New 🚀

Database Server Connections

You can now add a database server to the connections list and select one or more databases from that
server. All databases under a server share the same connection and scaffolding options, so you only
configure things once. Server connections are supported for SQL Server, PostgreSQL, MySQL, and
MariaDB.

Script Performance Improvements

Script startup and re-run speed was improved:

• Compilation results are cached so unchanged re-runs skip compilation entirely.
• Nuget dependency graphs and script dependencies are cached so resolution only occurs when needed.
• Framework assembly dependency cache is pre-warmed on a background thread at startup.
• Other similar optimizations for quicker re-runs.

.NET SDK Detection Improvements

NetPad now discovers all valid .NET installations on your system (user settings, environment
variables, user-level, system-level, PATH) and aggregates SDKs and runtimes from each. Previously,
only the first valid installation was used. When running a script, the correct dotnet executable
is resolved based on which installation contains the target framework's SDK.

User Interface

• Statusbar background color now changes to indicate script status (running, error, etc.), with
  unified status colors throughout the app.
• A context menu was added to the scripts explorer sidebar.
• Added separators between editor tabs and added tree nesting indicators in the explorer pane for
  better visual hierarchy.
• When text is selected in the editor, the statusbar now shows the number of selected chars (or
  lines).
• Style run/stop buttons with colored tints and flatten save/properties to icon buttons.
• Change open folder icons in scripts explorer to blue to indicate expanded state.
• Increase global border-radius for a softer look across all components.
• Better background colors for input controls.
• Add toolbar dividers to group action icons where needed.
• Reduced prominence of toolbar labels (SDK, Kind, etc.) for a cleaner look.
• Add more contrast to pane toolbar background.
• Switch package reference buttons to outline style for less visual noise.
• Window size and position are now remembered across Tauri app restarts (#370).

OmniSharp / IntelliSense

OmniSharp stability was improved:

• Requests to OmniSharp are queued and wait for OmniSharp to finish its internal initialization to
  prevent broken language server features when typing in scripts before OmniSharp is finished
  loading.
• OmniSharp now detects process crashes and auto-restarts.

NetPad CLI (npad) v0.2.0

The CLI tool received a major update with many new commands and usability improvements. See
the CLI wiki for more info and usage details.

New commands:

• new: Create .netpad scripts or plain .cs files with options for kind, SDK, connection,
  and more
• show: Inspect a script's metadata and source code (renamed from cat, BREAKING CHANGE)
• logs show/tail/rm/clear: View, follow, and manage log files
• settings show/edit: View settings as a table or JSON, or open in default editor

New features:

• run is now the default command: npad myscript works without typing run
• Stdin piping: echo 'Console.WriteLine("hi")' | npad
• --eval (renamed from --code): Run inline C# from the command line, BREAKING CHANGE
• --format json: NDJSON output for piping to jq and other tools
• --kind option on run: Override a script's kind at runtime
• Interactive script picker: Prompts for selection when multiple scripts match
• Script exit codes: Propagates meaningful exit codes (0=success, 1=runtime failure,
  2=compilation failure, 130=cancelled)
• Short aliases: -e, -s, -c, -O, -b, -f, -m, -v, -k and command aliases (
  ls, log)
• Various TUI improvements and fixes

Install or update via:

dotnet tool install -g netpad.cli
dotnet tool update -g netpad.cli

Coming Soon: NetPad MCP Server

A Model Context Protocol (MCP) server for NetPad is in the works and nearly complete. It will let AI
assistants (like Claude Code) and other MCP clients to create, run, and manage scripts directly
through NetPad. Stay tuned!

Build & Release

• Added Linux ARM64 and Windows ARM64 builds for both Electron and Tauri.
• Support for alpha/beta pre-release version names in app update checks.
• Unified release workflow: a single release.yml replaces the old pack-electron.yml and
  pack-tauri.yml with support for alpha/beta pre-releases.

Fixes 🐛

• Fix The filename, directory name, or volume label syntax is incorrect error (#390). Thanks to
  @wuuer.
• Fix NuGet dependency resolution issues including native library resolution (#350).
• Fix script counts in the explorer sidebar.
• Fix using scale for precision in database structure column details.
• Fix OmniSharp bugs related to changing a script's SDK and finding installed SDK locations.
• Fix script-host not loading the correct SDK in release builds.
• Fix multiple NetPad instances sharing temp directories causing IOExceptions: temp directories are
  now scoped per process.
• Fix .NET backend not stopping gracefully on Windows when using the Tauri app.
• Fix memory leaks and race conditions in several areas.
• Fix duplicate script save overwriting existing scripts in web shell.
• Fix unrelated script runs to serialize against each other.

This release adds .NET 10 support, some new features, and a new CLI tool! All feedback is welcome.

🎯 A special thanks to Andrea Bondanini (@sbundaz) for contributing a number of new features in this release.

What's New 🚀

.NET 10 Support

.NET 10 SDK is now supported. New scripts will automatically target .NET 10 if you have it installed.

Oracle Data Connections

You can now create Oracle database connections. Thanks to Andrea Bondanini (@sbundaz) for the contribution.

IL Viewer

NetPad now has an IL Viewer. You can find it by opening the Code pane located at the bottom left, and then swithcing from Syntax Viewer to IL Viewer.

Thanks to Andrea Bondanini (@sbundaz) for helping with this.

User Secrets Manager

A User Secrets management pane was added to the bottom pane ribbon. Secrets can be accessed in your code using Util.Secrets:

string value = Util.Secrets.Get("secretkey");

You can also list/add/update/remove secrets directly from code using these methods on Util.Secrets:

void Save("secretkey", "value");
UserSecret[] List();
UserSecret? GetSecret(string key);
bool Delete(string key);
void Delete(Func<UserSecret, bool> filter);

Wiki page

NetPad CLI (npad)

npad is a new CLI tool that brings NetPad to the terminal. You can use it to execute scripts, standalone C# files, and even code you type on the command prompt directly.

It can be installed as a dotnet tool:

dotnet tool install -g netpad.cli

See the wiki page for usage and examples.

The following is planned for npad:

1. Faster script execution. The first time you run a script it is built and cached. Subsequent runs are much faster. The goal is to speed up that initial run.
2. Ability to pass arguments to your scripts.
3. Build a script into an executable.

npad will have a different release cycle than NetPad (GUI), and will see some frequent updates in the near future with CLI-specific features and enhancements.

Other Updates

• New Data Protection methods were added to Util that you can use to protect/unprotect data. See Util.Protect() and Util.Unprotect() methods and thier overrides.
• UI Updates:
  • A small refresh to tabs and panes.
  • App status messages in the statusbar can be dismissed by right-clicking the message.
  • Better UI for errors in the output pane for better readability.
  • Changed the formatting of how long a script took to run on the bottom left.
  • Swap the order of the Settings and Pin Window icons in the titlebar.
• Update OmniSharp to v1.39.15.

Fixes 🐛

• Fix OmniSharp doesn't perform 2nd Quick Fix suggestion (#365).
• Fix bug that caused script output to no show after manually stopping a script.
• Fix Optimize dropdown not show actual selected value.

Installers

NetPad has 2 release channels:

• Stable: The Electron version of NetPad. Installers that start with netpad
• vNext: Uses a native Rust-based shell. Installers that start with netpad_vnext

Both channels have the same feature set and are equally maintained. The native vNext version is lighter on system resources and planned to become the main package. At which point, the Electron version might be deprecated.

See wiki for more info.

What's New 🚀

Export Data Connections

You can now scaffold a database connection and export it to a C# project by right-clicking a connection and selecting "Scaffold to C# Project". This can be a great way to jump start a new app, or build an assembly to use in your own applications.

Vim Keybindings (experimental)

The editor now has vim support (#238). It can be enabled by:

• Going to Settings > Editor
• Keyboard shortcut (Alt + V). Keybinding can be changed in Settings.

This functionality is mainly powered by monaco-vim which uses CodeMirror's implementation behind the scenes.

Future Plans
I plan to add the following in future releases:

• Command history (pressing up/down arrows for command history).
• More keybindings and commands that target the application interface and not just text editing; example: selecting a connection.

Feedback Requested
This is an experimental feature. I'd love to hear your feedback and comments on issues or ways to make it better. The monaco-vim library isn't very well maintained unfortunately but I wanted to try it out before rolling my own.

User Interface

• When NetPad opens, it now restores all open scripts from the last session. Previously, only unsaved scripts were restored (#336).
• Scripts in the Explorer pane are sorted case-insensitive (#344).
• New spinner icon for when a script is running.
• New alert dialogs.
• Native select file dialogs instead of HTML file inputs.

Scripts

• Source Generator support (#233). Thanks to @jesterret
• Support for .NET framework version preprocessor symbols. You can now use preprocessor symbols like NET8_0_OR_GREATER in your scripts. More info. Thanks to @jesterret
• Dump() now hides indexer properties (#349).
• New async versions of Dump() (#326). Thanks to @jesterret

App Updates

• NetPad is updated to .NET 9.
• Electron updated to v36 by switching from Electron.NET (still on Electron v23) to ElectronSharp (a fork of Electron.NET) which brings a number of security fixes and performance improvements. Special thanks to @Jogai for putting alot of work into making this happen.
• Node.js updated to v22.
• Code:
  • Improved thread-safety.
  • Fixed some memory leaks.
  • Performance improvements.
  • Code cleanup, fixed some warnings and more code documentation.

Fixes 🐛

• Fixed OmniSharp not starting, and Intellisense not working, (most commonly on macOS).
• Fix Dump() for properties on derived types (#323). Thanks to @jesterret
• Fix inability to browse & select an assembly to reference in vNext (#331).
• Fixed OmniSharp code diagnostics not resetting after user restarts OmniSharp server from Command Palette > Developer: Restart OmniSharp Server.
• Fixed Electron selecting the wrong button when Esc is pressed on some dialogs.

Next Minor Version (v0.10.1)

v0.10.1 is in the works and will include .NET 10 Preview SDK support as well as fixes for some bugs that I didn't get a chance to address in this release.

Installers

NetPad has 2 release channels:

• Stable: The Electron version of NetPad. Installers that start with netpad
• vNext: Uses a native Rust-based shell. Installers that start with netpad_vnext

Both channels have the same feature set and are equally maintained. The native vNext version is lighter on system resources and planned to become the main package. At which point, the Electron version might be deprecated.

Full Changelog: v0.9.0...v0.9.1

Its been a while since the last release; war affects us all unfortunately.

Until now, packaging binaries for every supported platform was done manually. It was slow, error-prone and just no fun at all. We now have automated CD pipelines that makes it much easier. The plan is to have a more frequent release cycle. There are a lot of new improvements coming—stay tuned.

If you like NetPad, please star the repo 🌟!

What's New 🚀

Database Connection Query Speed

A main focus of this release was improving the user experience when running scripts with database connections (#196).
Prior to this release, scripts targeting a connection were slow to start, mainly due to Entity Framework's long startup
time. A new execution model was introduced so that this cost is only paid on the first run of a script, later runs will
be much faster even if your code changes.

Utility Helper

A handy new Util class is now available (#166) to enhance your scripting experience with built-in helpers for
dumping data, caching, environment access, and more.

See the Util wiki page.

Caching

The Util class has an in-memory Cache property that can be used to store data and then access it in later script
runs. Example:

var albums = Util.Cache.GetOrAdd("albums", () => Albums.ToArray());
var albums = await Util.Cache.GetOrAddAsync("albums", () => await Albums.ToArrayAsync());

MemCache Pane

A new pane called MemCache will now appear on the right side of the interface, displaying the values you've cached
in code. Clicking an item in this pane will dump it to the output pane. Hover over an item to see more info.

User Interface

Various UI improvements for better usability, clearer visuals, and more intuitive interactions across the app.

• The Save icon now shows an indicator when a script has unsaved changes, and is disabled when not needed.
• The Namespaces pane textbox has improved styling and a new icon.
• The selected editor tab is now more visually distinct.
• Icon colors have been subtly refined for better consistency.
• Pane dividers now show clearer drag handles on hover.
• The Scripts Explorer displays the number of scripts in each folder.
• You can now switch the layout direction of the Explorer pane.
• Status messages in the status bar can be dismissed with a right-click.
• Minor styling update to the "References" link in the editor.
• Two new menu items have been added to improve navigation and accessibility:
  • Tools — A new top-level menu with some utilities and tools.
  • Help > Wiki — A new submenu item that opens NetPad's wiki pages for quick access to documentation.

Status Visibility

Script status is now easier to see at a glance. Editor tabs display a colored line that indicates when a script is
running or stopping, helping you quickly spot active scripts across tabs.

I'm experimenting with this subtle visual cue and would love your feedback—would you prefer something more prominent,
like a colored status bar? Let me know what feels right to you.

The status bar at the bottom of the window also provides clearer, more informative messages about script activity.
Additionally, the timer on the far left has been improved: it now more accurately reflects the actual execution time
of your script, excluding setup overhead that was previously included.

Others

• Improved reliability of the "Stop Script" mechanism.
• Wrapped long documentation text in IntelliSense popups for better readability.
• New installations now default to colorful icons (Settings > General > Icon Theme).
• Updated and expanded several Wiki pages.

Fixes 🐛

• Fixes #280: Disappearing output when switching tabs.
• Fixes #287: Private NuGet sources breaking script execution.
• Fixes #296: Issue loading referenced assemblies.
• Fixes #301: User input textbox blocking output.
• Fixes for NetPad vNext not running on some setups.
• Reduce the instances where OmniSharp fails to provide syntax highlighting and intellisense.
• Fix syntax highlighting styles of dumped code strings.
• Fix some zoom menu items.
• Captures current code when user clicks Run to prevent further code edits from affecting current run.
• Other minor fixes and optimizations.

Installers

NetPad comes in 2 flavors:

• Electron: Installers that start with netpad
• Native Shell: Installers that start with netpad_vnext

Both flavors have the same feature set. The native vNext version is lighter on system resources and will eventually become the main package. At which point, the Electron version will be deprecated.

What's New 🚀

New Database Connection Providers

You can now add MySQL and MariaDB connections in NetPad. Special thanks to @SimonNyvall!

A Native Shell (vNext Preview)

This update introduces a new native shell built using Tauri, a Rust-based framework, that greatly reduces memory usage, startup time, and app size!

The new shell substitutes the Electron.js shell NetPad has been using so far. You will find new installers available that use the new native shell with names starting with netpad_vnext. Electron shell installers are still available, and will continue being distributed until things are stable with vNext. Both versions of NetPad can be installed and run side-by-side. It would be really helpful if you could please provide your feedback in an issue (if you're having trouble), in this discussion or on Discord.

If you'd like to read more about this change, take a look at this issue. Here are some stats:

App Size

Memory Usage

Known Limitations with vNext

• If you have your NetPad settings configured to use the native titlebar instead of the integrated one, menu auto-hide does not work yet (not an issue on macOS).
• The main window does not currently remember its previous position and size when you close and restart NetPad.
• The Electron version of NetPad will show you a desktop notification when a script finishes execution and NetPad is in the background. vNext currently does not.
• Some Linux installers are not yet available for vNext, namely: pacman, flatpak and snap
• If you're on Linux and when you launch the app you get an empty window, try disabling DMABUF: export WEBKIT_DISABLE_DMABUF_RENDERER=1. This is an upstream bug with NVIDIA proprietary drivers on some installations. If that doesn't work, try one of these instead:
  • WEBKIT_DISABLE_COMPOSITING_MODE=1
  • __NV_PRIME_RENDER_OFFLOAD=1

Fixes for some or all of the above will be included in the next release.

Others

• Removed .NET 6 dependency: having a .NET 6 runtime or SDK installed is no longer required.
• If you want to use .NET 9 in your scripts you will need .NET 9 Preview 3 SDK or later installed.
• Improvements to data connection scaffolding.
• New scripts will use the latest stable .NET SDK. Previously the latest SDK was auto-selected regardless if it was stable or preview.
• New script names will use the next highest available number. Example: if you have "Script 1" and "Script 3" open, creating a new script will give it the name "Script 4". Before it was named "Script 2" which was confusing.
• Update OmniSharp Server to v1.39.12.
• More details are shown about errors that occur during scaffolding database connections.
• Minor styling changes:
  • The Production marker in the connections list is right aligned and is now just the letter P.
  • Fixed weird line at the top of the app logo.

Fixes 🐛

• Fixed Zoom menu items and their corresponding keyboard shortcuts
• Fixed an issue running scripts targeting SQLite connections on macOS
• Fixed writing char values to the console (#225)
• Fixed incorrect latest version label in NuGet search window (#227)
• Fixed namespace collisions when referencing some NuGet packages (#246)
• Fixed NuGet search not working when user has an unreachable feed configued in nuget.config (#261)

Coming Soon 🏁

We're currently working on fulfilling requests from the issue tracker as well as a few new features:

• A new CLI tool that you can use to run C# scripts from the command line.
• Faster database queries.

What's New 🚀

Syntax Tree Visualizer

A new "Code" pane was added with a Syntax Tree visualizer that updates in real-time as you type.

• Hovering over a node in the syntax tree will highlight that text range in the editor.
• Single-click a node to bring that code into view (if it isn't already).
• Double-click a node to select that text range in the editor. Focus switches to the editor when you do this so you can start typing right away.
• The right side shows the code each node in the tree represents, making it easier to quickly locate the code want you want to inspect.
• You can show the line/char span numbers each node represents by clicking the corresponding button in the Code pane toolbar.

image

Others

• Icon buttons styling improved and unified
• You can hide any pane with Shift + ESC keybinding
• Output pane
  • Empty collections are rendered a bit differently and other minor formatting changes to output
  • Moved next/previous output nav controls to the toolbar in Results
  • Added next/previous nav controls and clear button to the SQL toolbar
  • You can switch to the Results and SQL tabs by using ALT + 1 and ALT + 2 respectively

Maintenance

The majority of the effort spent since the last release has been on restructuring the solution, simplifying and making it easier to maintain, review and contribute to. Another round is coming up soon, mainly on the client side, but the majority of it is completed. If you're interested in more info see #211.

I plan to add documentation soon that explains the high level concepts and structure of the solution to help facilitate review and contribution.

If anyone has any thoughts or discussion points I'd love to hear them. Feel free to open a discussion/issue on the topic or hit me up on Discord.

Fixes 🐛

• Fixed a bug causing intellisense and other OmniSharp features to stop working if .NET 7 is not installed (#208, #214, #220)
• Fixed incorrect max-length input validation when changing max collection length to serialize in settings (#209)
• Fixed an error during HTML serialization (#217)
• Fixed bugs in Console.ReadLine() functionality including #218

Full Changelog: v0.7.1...v0.7.2

Preview 7.1

If you like NetPad, please star the repo 🌟!

What's New 🚀

.NET 9 Preview

Added support for .NET 9 Preview and Entity Framework Core 9 Preview 3.

Data Connections

Create Similar Connection

A new option now exists in the data connection context-menu to duplicate a connection.

Entity Framework Compiled Models

Entity Framework takes time to initialize on first use. The larger the data model, the more time it needs. For large models (100s or 1000s of entities and relationships) script startup can be sped up using a compiled model. An option to use a compiled model for a data connection now exists in Connection: Properties > Scaffolding.

Note that using compiled models is not effective for smaller models, and comes with some limitations. It is recommended to only use this option if you need it.

Editor Styling

The editor has some pre-defined themes you can now pick from in Settings > Editor. These themes come from the monaco-themes project.

Example, the GitHub Dark theme:

image

You can also tweak the current editor theme using the themeCustomizations property in the Monaco options editor.

Example:

"themeCustomizations": {
 // General editor colors
 "colors": {
 "editor.background": "#282a36"
 },
 // Semantic highlighting token styles
 "rules": [
 {
 "token": "interface",
 "foreground": "50fa7b",
 "fontStyle": "underline"
 }
 ]
}

See IColors and ITokenThemeRule for the definition of the colors and rules properties respectively.

See wiki for more info.

App Styling

The new Settings > Styles was added as a way to define custom styles that apply to the whole application.

For example to increase the font size of output:

.dump-container {
 font-size: 1.25rem;
}

This feature also works great with the ability to specify CSS classes you want a dumped value to have, introduced in v0.7.0:

myObj.Dump(css: "important");

.important {
 background-color: salmon;
}

You can also override CSS variables on the built-in theme-netpad-dark and theme-netpad-light themes. Here's an example customizing the dark theme with the Dracula theme color palette:

.theme-netpad-dark {
 --drac-light: #343746;
 --drac-dark: #22222c;
 --text-color: #F8F8F2;
 --background-color: var(--drac-dark);
 --list-background: var(--drac-light);
 --form-control-background-color: #343746;
 --active-color: #dbb5fa;
 --script-toolbar-background: #242632;
 --pane-ribbon-background: var(--drac-light);
 --pane-background: var(--drac-dark);
 --pane-toolbar-background: var(--drac-dark);
 --dialog-background: var(--drac-dark);
 --tab-background: #333541;
 --tab-active-background: #242632;
 --tab-active-text-color: #fffff;
 --scrollbar-thumb-color: #777777;
 --splitter-color: #2b2d39;
}

image

See wiki for more info.

NuGet

NetPad will recognize additional NuGet sources added to your Nuget.Config file (#119). Thank you @jsamse for that contribution.

There is no UI to manage NuGet sources in NetPad so far so you'll have to add them manually. More info

Media File Sizing

Media files will now be rendered in their original size, but you can also specify size using the DisplayWidth and DisplayHeight properties:

new Image("/path/to/img.png")
{
 DisplayWidth = "128px",
 DisplayHeight = "128px"
}.Dump();

Or using extension methods:

// Individually
Image.FromPath("/path/to/img.png")
 .WithDisplayWidth("100%");
 .WithDisplayHeight("400px");
// Together
Image.FromPath(imageFile).WithDisplaySize("100%", "400px");

See the wiki for more info.
