# Building Lambda functions with PowerShell

The following sections explain how common programming patterns and core concepts apply when you author Lambda function code in PowerShell.
Lambda provides the following sample applications for PowerShell:
+ [blank-powershell](https://github.com/awsdocs/aws-lambda-developer-guide/tree/main/sample-apps/blank-powershell) – A PowerShell function that shows the use of logging, environment variables, and the AWS SDK.
Before you get started, you must first set up a PowerShell development environment. For instructions on how to do this, see [Setting Up a PowerShell Development Environment](powershell-devenv.md).
To learn about how to use the AWSLambdaPSCore module to download sample PowerShell projects from templates, create PowerShell deployment packages, and deploy PowerShell functions to the AWS Cloud, see [Deploy PowerShell Lambda functions with .zip file archives](powershell-package.md).
Lambda provides the following runtimes for .NET languages:
| Name | Identifier | Operating system | Deprecation date | Block function create | Block function update | 
| --- | --- | --- | --- | --- | --- | 
| .NET 10 | `dotnet10` | Amazon Linux 2023 | Nov 14, 2028 | Dec 14, 2028 | Jan 15, 2029 | 
| .NET 9 (container only) | `dotnet9` | Amazon Linux 2023 | Nov 10, 2026 | Not scheduled | Not scheduled | 
| .NET 8 | `dotnet8` | Amazon Linux 2023 | Nov 10, 2026 | Feb 1, 2027 | Mar 3, 2027 |
