Error with project files not finding objects or razor tags

[craiggodfrey]

Type: Bug

When opening files, whether .cs or .razor, the file gets a lot of red error lines and says it cannot find the object even though they are part of the project. If I go through and open every file, then the red error lines go away.

Can you provide some more information?

1. C# extension version and if you're using devkit
2. the logs from the 'C#' output window
3. some of the exact error messages you're seeing (screenshots are always useful)

When I click on each file in the project, these error and warning squiggly lines go away, and the red project file names change to white. As I click through the project files, I get more and more of these squiggly lines, until I click through all of the files then they go away.

C# extension version: v2.15.30 C# devkit version: v1.3.10 IntelliCode for C# devkit version: v0.1.26

I don’t know where the logs are. There isn’t anything in the output tab.

Also, this only happens when I reopen the project, or if I open the project in visual studios then go back to vscode.

@davidwengier - any known problems with re-using incorrect build assets (or mismatch in build assets) between VS and vscode for Razor files?

[davidwengier]

Been a few reports recently it seems, like https://github.com/dotnet/vscode-csharp/issues/6921 and https://github.com/dotnet/vscode-csharp/issues/4580#issuecomment-1912001583, where maybe our closed file stuff has changed. We could easily be broken by a change to Roslyn here too, so might not be something we're aware of. Will put this in triage.

I also opened my project with Visual Studio one time and since then the issue persists. Tried clean, rebuild, etc. But even deleting and cloning again doesn't fix it.

When opening it in the WSL it works perfectly fine.

Update: When cloning on another Windows system the issue appears again. Also I encountered the issue one time in WSL, but here it resolved after reloading vs code, while in Windows I haven't found a way to resolve it by now.

Hi!

I had downgraded C# extension from v2.22.3 to v2.18.16, seems to be working now. I had similar issues but only for .razor files and in Program.cs. Current extension list: C#: v2.18.16 C# Dev Kit: v1.4.29

I will post update it starts reproducing again. Program.cs showed one errror for App.razor, it did not recognized the generated class I've fixed this issue by adding code behind and partial class for App.razor

public partial class App : ComponentBase
{
        
}

[ThisIsPedroMoreira]

I have this error too. Any update on this? @davidwengier
