Update documentation to reference Blazor helpers from Microsoft.Identity.Web package

[Copilot]

Blazor authentication helpers (BlazorAuthenticationChallengeHandler and LoginLogoutEndpointRouteBuilderExtensions) now ship in Microsoft.Identity.Web v3.3.0+. Documentation currently instructs users to copy files from the skill folder.

Changes

Helper files (.github/skills/entra-id-aspire-authentication/)

• Added header comments indicating inclusion in v3.3.0+
• Files retained for AI skill reference and documentation

SKILL.md

• Removed Copy-Item PowerShell commands
• Updated implementation checklist: replaced "Copy files" steps with "Verify package version includes helpers"
• Updated file modification table to remove copy references

aspire.md

• Replaced section 2.4 "Copy helper files from skill folder" → "Blazor authentication helpers"
• Marked <details> code blocks as "(Reference)" with note about package inclusion
• Updated implementation checklist and files table
• Updated AI Skills section to clarify reference-only status

Before:

$skillPath = ".github/skills/entra-id-aspire-authentication"
Copy-Item "$skillPath/LoginLogoutEndpointRouteBuilderExtensions.cs" "MyService.Web/"
Copy-Item "$skillPath/BlazorAuthenticationChallengeHandler.cs" "MyService.Web/"

After:

These helpers ship in the Microsoft.Identity.Web NuGet package (version 3.3.0+). Simply add using Microsoft.Identity.Web; — no file copying required.

Note

⚠️ Do not merge until Microsoft.Identity.Web v3.3.0+ is released with integrated helpers.

Original prompt

Goal

Update all documentation and skills to reference the Blazor helpers (BlazorAuthenticationChallengeHandler and LoginLogoutEndpointRouteBuilderExtensions) from the official Microsoft.Identity.Web NuGet package, instead of instructing users to copy files from the skill folder.

Context

Once Microsoft.Identity.Web ships with the integrated Blazor helpers (from Issue #1), users will no longer need to manually copy helper files. This PR prepares the documentation updates — it should NOT be merged until Microsoft.Identity.Web is released with the Blazor helpers.

Tasks

1. Update .github/skills/entra-id-aspire-authentication/SKILL.md

Find and update sections that reference copying files from the skill folder. Change instructions like:

Before:

Copy these helper files from the skill folder:
- `BlazorAuthenticationChallengeHandler.cs`
- `LoginLogoutEndpointRouteBuilderExtensions.cs`

After:

These helpers ship in the `Microsoft.Identity.Web` NuGet package (version X.X.X+). Simply add `using Microsoft.Identity.Web;` — no file copying required.

Also update any PowerShell copy commands like:

$skillPath = ".github/skills/entra-id-aspire-authentication"
Copy-Item "$skillPath/LoginLogoutEndpointRouteBuilderExtensions.cs" "MyService.Web/"
Copy-Item "$skillPath/BlazorAuthenticationChallengeHandler.cs" "MyService.Web/"

To indicate these are no longer needed.

2. Update docs/frameworks/aspire.md

Find section 2.4: Copy helper files from skill folder and similar references. Update to indicate:

• The helpers now ship in the package
• No manual file copying required
• Just reference Microsoft.Identity.Web and use the classes directly

Update the Implementation checklist to remove:

• [ ] Copied LoginLogoutEndpointRouteBuilderExtensions.cs from skill folder
• [ ] Copied BlazorAuthenticationChallengeHandler.cs from skill folder

Replace with:

• [ ] Verified Microsoft.Identity.Web version includes Blazor helpers (vX.X.X+)

3. Update any <details> blocks showing file contents

The <details> blocks in aspire.md that show the full source of:

• LoginLogoutEndpointRouteBuilderExtensions.cs
• BlazorAuthenticationChallengeHandler.cs

Should be updated to note these are reference only — the actual implementation ships in the NuGet package.

4. Keep the source files in .github/skills/entra-id-aspire-authentication/

Do NOT delete BlazorAuthenticationChallengeHandler.cs and LoginLogoutEndpointRouteBuilderExtensions.cs from the skills folder. They serve as:

• Reference for the AI skill
• Historical documentation
• Fallback for older package versions

Add a comment at the top of each file:

// NOTE: This file is included in Microsoft.Identity.Web package (vX.X.X+).
// This copy is maintained for AI skill reference and documentation purposes.
// For production use, reference the NuGet package directly.

Important Notes

⚠️ DO NOT MERGE this PR until Microsoft.Identity.Web is released with the Blazor helpers integrated.

The PR should be created and ready for review, but kept in draft or with a "do not merge" label until the package is published.
