c# – How to disable the pink Razor feature warnings in Visual Studio?


I’m working on an ASP.NET Core MVC project in Visual Studio 2022.

Lately, I keep seeing these warning messages at the top of the editor:

  • Feature ‘Razor Diagnostics Feature’ is currently unavailable due to an internal error.
  • Feature ‘Razor InlayHint Feature’ is currently unavailable due to an internal error.
  • Feature ‘Razor LinkedEditingRange Feature’ is currently unavailable due to an internal error.

They appear every time I open a .cshtml file, and it’s very annoying.
I just want to turn them off completely (I don’t need those Razor IntelliSense features).

I’ve already tried:

  • Resetting Visual Studio settings
  • Clearing ComponentModelCache
  • Searching in Tools → Options → Text Editor → Razor, but couldn’t find any option related to “diagnostics” or “inlay hints”

How can I completely disable these Razor features or prevent these warnings from showing up?

Here’s what it looks like

What I tried:

  • Disabled IntelliSense for Razor files in Tools → Options → Text Editor → Razor
  • Cleared ComponentModelCache folder
  • Reset all Visual Studio settings

What I expected:

The warning messages (“Razor Diagnostics Feature is currently unavailable…”) would disappear completely when editing .cshtml files.

What actually happened:

The pink bar and warning messages still appear every time I open a Razor file.
