Visual Studio errors in .cshtml for new Blazor project that compiles fine? how to disable it?

Question

I just created new blazor project via

dotnet new blazorhosted

and opened FetchData.cshtml, but VS threw 9 errors at me.

Of course whole project is compiling & works fine, but it's very annoying

How can I disable showing errors for .cshtml files?

Sometimes Blazor blows up on me and throws errors on lines that have no errors, just like this.

I close the file(s), clean the entire solution, restart my computer, then rebuild just the project I am working on and it goes away.

Maybe that will work for you too.
