Assembly conflict when trying to type something in Razor file #7469

Closed pontakornth closed 2 months ago

pontakornth commented 2 months ago

Type: Bug

Issue Description

When I try to type something in .cshtml file, there will be a random error. After I look into the log, I see assembly conflict.

The issue appears on both release and pre-release version of C# Dev Kit.

Steps to Reproduce

  1. Open VSCode
  2. Open an ASP.NET Core project with Razor Page
  3. Open a .cshtml file
  4. Type @Html. should make the error appear.

Expected Behavior

Auto complete appears if available. No effect on other files

Actual Behavior

Auto complete appears and then disappears. After that, autocomplete and some syntax highlighting in C# files do not work.
