Descrizione

info-needed

Type: Bug

Steps to Reproduce
  1. Open a project containing Blazor .razor files in VS Code.
  2. Open the GitHub Pull Requests extension.
  3. Check out or open a pull request.
  4. Navigate to a modified .razor file in the pull request.
  5. Open the file in the side-by-side diff editor.
Actual Behavior

The diff editor displays red squiggly lines across almost every line of code on both sides of the comparison.

The Problems panel also reports numerous C# syntax errors, primarily CS1025: Single-line comment or end-of-line expected, even on valid code and comments.

This makes reviewing changes extremely difficult because the error indicators obscure the actual differences.

Expected Behavior

The pull request diff viewer should display .razor files with proper syntax highlighting and without false C# diagnostics.

Additional Information

The issue appears to be related to how Razor/C# language diagnostics are handled when files are opened through the GitHub Pull Requests diff viewer.
