Problem

The same extensive parameter binding content (~456 lines) was duplicated across multiple documentation pages:

  • Minimal APIs quick reference (minimal-apis.md)
  • Version-specific quick references (minimal-apis8.md, minimal-apis9.md)
  • Dedicated parameter binding article (parameter-binding.md)

This duplication caused several issues:

  • Reader confusion: Users encountered identical content in multiple places, questioning why it appeared twice and whether there were differences
  • Overwhelming content: The sheer volume of duplicated content made quick reference pages difficult to navigate
  • Broken navigation: Heading levels (h3) in the included content didn't generate entries in the "In this article" navigation panel, making it hard for readers to jump to specific sections

Quick reference with Parameter binding section circled

Parameter binding article showing empty "In this article" navigation

Solution

1. Created Brief Summary for Quick References

Created a new include file parameter-binding-summary8-10.md (31 lines) that provides:

  • Concise overview of parameter binding concepts
  • List of supported binding sources
  • Key features in bullet points
  • Link to the full parameter binding article for detailed information

This reduces the quick reference content to ~7% of the original size (well under the 1/10 target).

2. Updated Quick Reference Files

Updated three quick reference files to use the summary instead of full content:

  • minimal-apis.md (main quick reference for .NET 10+)
  • minimal-apis8.md (version-specific for .NET 8.0)
  • minimal-apis9.md (version-specific for .NET 9.0)

3. Fixed Heading Structure

Adjusted heading levels in parameter-binding8-10.md:

  • Main sections: h3 (###) → h2 (##)
  • Subsections: h4 (####) → h3 (###)

This ensures main sections now appear in the "In this article" navigation panel when viewing the dedicated parameter binding article.

4. Updated Metadata

  • Added proper frontmatter to the new summary file (author, ms.date, ai-usage)
  • Updated ms.date to 10/23/2025 in modified files

Result

✅ Full parameter binding documentation appears only in the dedicated article
✅ Quick references have brief, scannable summary with link to full content
✅ "In this article" navigation properly displays parameter binding sections
✅ Eliminated duplicate content and improved documentation structure

This section details on the original issue you should resolve

<issue_title>De-duplicate documentation on parameter binding</issue_title>
<issue_description>### Description

Problem

For ASP.NET Core releases 8-10, the same content on parameter binding appears in two different places. It appears in the "Parameter binding" article (this one) and also in the "Parameter binding" section of the Minimal APIs quick reference:

Image

The content in both places comes from the same source:

aspnetcore/fundamentals/minimal-apis/includes/parameter-binding8-10.md

There are several problems with this:

  • duplicate content can confuse readers (Why does this appear in two places? Are there differences?)
  • The shear bulk of this content can be daunting to readers
  • Because the same content is used in a top-level article and in a section within an article, the headings tags used (h3 and above) don't get picked up and displayed in the "In this article" nav normally shown in the right hand pane.
Image

Desired solution

  • The "Parameter binding" section of "Minimal APIs quick reference" should be changed to a brief summary of the full content (1/10 the size or less) with a link to the full article.
  • The headings in the "Parameter binding" article should be adjusted so that they generate a proper "In this article" nav in the right hand pane.

Issue Summary

There is duplicate content about parameter binding appearing in two different places in the ASP.NET Core documentation, which can cause confusion for readers.

Detailed Analysis

The parameter binding documentation appears in:

  • The "Parameter binding" article: /aspnet/core/fundamentals/minimal-apis/parameter-binding
  • The "Minimal APIs quick reference" article in the parameter binding section

Both places include the same content from a single source file:
aspnetcore/fundamentals/minimal-apis/includes/parameter-binding8-10.md

Problems Caused by Duplicate Content

  • Readers may be confused by seeing the same content in two different places
  • The bulk of repeated content is overwhelming
  • The heading structure doesn't work properly in both contexts, affecting the "In this article" navigation panel

Files to Modify

Parameter Binding Article

  • File: aspnetcore/fundamentals/minimal-apis/parameter-binding.md
  • Current Implementation: Includes the parameter-binding8-10.md include file directly

Minimal APIs Quick Reference Article

(Not shown in provided files, but referenced in the issue)

  • Needs modification to replace the full parameter binding content with a brief summary and link

Required Changes

For the Parameter Binding Article

  • Keep the full content but adjust heading levels to ensure proper navigation
  • Line 16 contains: [!INCLUDE parameter-binding]
  • No changes needed to this file structure, but headings in the include file might need adjustment

For the Minimal APIs Quick Reference Article

  • Replace the include statement that adds the full content with a brief summary
  • Add a prominent link to the dedicated Parameter binding article
  • This would reduce the duplicate content significantly

Technical Details

  • Both files target .NET versions 7.0 and later (monikerRange: '>= aspnetcore-7.0')
  • The Parameter binding article is actively maintained (last updated: 10/22/2025 according to the metadata)
  • The included file (parameter-binding8-10.md) is extensive, with over 450 lines of documentation

Recom...

Fixes #36251

@mikekistler, hopefully this feels like the right balance of summary/intro on Parameter binding before linking off to the extensive details.

This looks like a good plan; I like the way it's organized. But for future content developers who need to work on these files it would be good to have a note in a comment, possibly an include file, explaining what goes where and what the heading levels need to be -- that would go at the top of each of these files.

Added editorial comments in main file to clarify the organization and level of detail that goes into it and its relationship to the other includes and links to external files that contain more details.
