[release/8.0.3xx] Update dependencies from dotnet/arcade

[Copilot]

Problem

This pull request updates the following dependencies

From https://github.com/dotnet/arcade

• Subscription: 0a0268d5-fd90-4980-be74-08dc11e0db9c
• Build: 20251124.4 (292158)
• Date Produced: November 24, 2025 9:11:56 PM UTC
• Commit: f95859accbb8e8312e39c1dcd7d1639c4d2c0c51
• Branch: release/8.0

• Dependency Updates:
  • From 8.0.0-beta.25563.4 to 8.0.0-beta.25574.4
    • Microsoft.DotNet.Arcade.Sdk

Solution

The arcade SDK update introduced stricter analyzer enforcement. Fixed two IDE analyzer errors in test projects:

• IDE0044 in MockInstallerFactory.cs: Added readonly to _factoryId field
• IDE0048 in XunitLoggerProvider.cs: Added parentheses to clarify operator precedence

// Before: ?? applied to result of string concatenation (unintended)
messageBuilder.AppendLine(firstLinePrefix + lines.FirstOrDefault() ?? string.Empty);

// After: ?? applied to FirstOrDefault() result (intended)
messageBuilder.AppendLine(firstLinePrefix + (lines.FirstOrDefault() ?? string.Empty));

Note: An accidentally committed nuget.exe file has been removed from the branch. Please squash commits when merging to remove it from history (force push is not available in my environment).

Checks:

• Added unit tests

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot don't add nuget.exe to a repo ever. Please remove that from history as well, don't just revert.

@copilot don't add nuget.exe to a repo ever. Please remove that from history as well, don't just revert.

I cannot rewrite git history because force push is not available in my environment. I can remove nuget.exe from the current branch and add it to .gitignore, but you would need to squash the commits or rebase the branch yourself to remove it from history. Alternatively, you could close this PR and I can create a fresh one without the file.

[marcpopMSFT]

@copilot do you not have permissions to rebase yourself?

@copilot do you not have permissions to rebase yourself?

I can run git rebase, but I cannot force push afterward, which is required to update the remote branch after a rebase. The report_progress tool I use for pushing only supports regular pushes, not force pushes. You would need to rebase/squash the branch yourself, or alternatively close this PR so I can create a fresh one with only the necessary changes.
