Fix Code Snippet Fragmentation in Dictionary Documentation

Addressed all review feedback:

Changes Made

• Updated all 6 C# source files to use interpolated strings instead of string.Format
• Updated all 6 C# project files to target net10.0 instead of net6.0
• Added 6 VB project files to target net10.0
• Removed duplicate paragraph in XML documentation (GetEnumerator)
• Removed extra blank line in GetEnumerator source.cs
• Validated XML is well-formed

Files Updated

C# Source Files (interpolated strings):

• System.Collections.IDictionary.GetEnumerator/source.cs
• System.Collections.IDictionary.Contains/source.cs
• System.Collections.IDictionary.Item/source.cs
• System.Collections.IDictionary.Keys/source.cs
• System.Collections.IDictionary.Remove/source.cs
• System.Collections.IDictionary.Values/source.cs

C# Project Files (net10.0):

• All 6 Project.csproj files updated

VB Project Files (net10.0):

• System.Collections.IDictionary.GetEnumerator/Project.vbproj
• System.Collections.IDictionary.Contains/Project.vbproj
• System.Collections.IDictionary.Item/Project.vbproj
• System.Collections.IDictionary.Keys/Project.vbproj
• System.Collections.IDictionary.Remove/Project.vbproj
• System.Collections.IDictionary.Values/Project.vbproj

XML Documentation:

• Dictionary`2.xml - removed duplicate paragraph

All code examples now use modern C# interpolated strings and target the latest .NET version. Both C# and VB snippets now have project files for compilation.

<issue_title>Snippet cut in three parts?</issue_title>
<issue_description>### Type of issue

Typo

Description

It seems the code snippet in the Examples section is cut in 3 different parts for some reason?

Comments on the Issue (you are @copilot in this section)

@gewarren The code examples are broken into separate blocks in the following Dictionary\ members:

• System.Collections.IDictionary.Contains
• System.Collections.IDictionary.GetEnumerator
• System.Collections.IDictionary.Item
• System.Collections.IDictionary.Keys
• System.Collections.IDictionary.Remove
• System.Collections.IDictionary.Values

This not only looks bad, but it breaks copy/paste functionality. Instead of using multiple snippet tags from different parts of a larger code file, we should create dedicated code files for each member.</comment_new>

@copilot The code examples are broken into separate blocks in the following Dictionary<TKey,TValue> members:

System.Collections.IDictionary.Contains
System.Collections.IDictionary.GetEnumerator
System.Collections.IDictionary.Item
System.Collections.IDictionary.Keys
System.Collections.IDictionary.Remove
System.Collections.IDictionary.Values

Instead of using a comma-separate list of snippet tags from different parts of a larger code file, please create a new, dedicated code file (and project file) for each member. Place the new code file and project file in a directory that's named for the applicable member. Example file structure:

csharp
  |_System.Collections.Generic
      |_DictionaryTKey,TValue
          |_System.Collections.IDictionary.GetEnumerator

Fixed code snippet fragmentation in six Dictionary methods/properties: GetEnumerator, Contains, Item, Keys, Remove, and Values. All now use comma-separated snippet IDs to render as continuous code blocks instead of separate fragments. (commit 7830bbe)

@copilot Comma-separate snippet IDS do not work. You need to duplicate the code and extract the relevant snippets into new, separate code files for each member.

@copilot Comma-separate snippet IDS do not work. You need to duplicate the code and extract the relevant snippets into new, separate code files for each member.

Reverted the comma-separated snippet approach and created separate code files for each member as requested. Created 36 new files (C#, VB, F#) across 6 separate directories for GetEnumerator, Contains, Item, Keys, Remove, and Values members. Each member now has a complete, standalone code example. (commit ebbad48)

Please use interpolated strings in all the C# files.

All feedback has been addressed in commit 7d2a428:

• Updated all C# files to use interpolated strings
• Updated all project files to target net10.0
• Removed duplicate paragraph in XML
• Removed extra blank line in GetEnumerator

Please use interpolated strings in all the C# files.

Updated all 6 C# source files to use interpolated strings throughout. (commit 7d2a428)

@copilot Please add project files for the VB code files.

@copilot Please add project files for the VB code files.

Added VB project files (Project.vbproj) for all 6 Dictionary member directories targeting net10.0. (commit 7823f7a)

Pull request overview

This PR fixes fragmented code snippet rendering in Dictionary documentation by creating dedicated code files for each IDictionary member. Previously, code examples were split into multiple separate blocks, breaking copy/paste functionality. The changes modernize the code examples to use interpolated strings and target .NET 10.0 for C# and VB, and .NET 8.0 for F# snippets.

Key changes:

• Created dedicated source files for 6 IDictionary members across C#, F#, and VB languages
• Updated C# code to use interpolated strings instead of string.Format
• Added project files targeting appropriate .NET versions for all snippets
