Problems Window - Error States "Unable to open: File not found"

[DanJ210]

Posted this in VS Code first and they said that this was a C# extension issue and to post here.

This happens every now and then but often enough. I'll be shown errors and clicking on some will state that the file does not exist. There is a duplicate set of the same errors from the same file below. Both show a slightly different path. Have no idea what's happening here.

Is this workaround what you have to do with every project to ensure you don't get this issue?

In the .csproj add true inside

• VSCode Version: 1.33.1
• OS Version: 1803

Steps to Reproduce:

1. Very hard to reproduce. Seems random. Been running the same .Net Core app all day. All of a sudden this happened.
2. Doesn't seem like it has steps to reproduce.
3. Occurs with all extensions disabled.

Does this issue occur when all extensions are disabled?: Yes

Still getting this issue quite often.

@DanJ210 This sounds like a duplicate of https://github.com/OmniSharp/omnisharp-vscode/issues/1197 -- can you try the workaround discussed in that issue?

[DanJ210]

It sounds like the same issue. I suppose I can try the workaround.

[dombarnes]

Issue #1197 suggests this has now been fixed but I am still seeing the issues in v1.21.5 of the C# Extension
