Omnisharp-vscode: Why can't omnisharp/vscode load this sln file?

[ahmelsayed]

Issue Description

Trying to use vscode (with WSL remote development extention) with this project https://github.com/Azure/azure-functions-host doesn't work

Steps to Reproduce

git clone https://github.com/Azure/azure-functions-host
cd azure-functions-host
code .

Expected Behavior

To be able to select between WebJobs.Script.Tests.E2E.sln and WebJobs.Script.sln

Actual Behavior

Only WebJobs.Script.Tests.E2E.sln works. Changing to WebJobs.Script.sln throws this error

your 131072x1 screen size is bogus. expect trouble

and nothing happens.

Deleting WebJobs.Script.Tests.E2E.sln and restarting vscode, causes it to not even recognize the project as C#. Copying all the content from WebJobs.Script.sln to WebJobs.Script.Tests.E2E.sln makes it work fine.

Logs

I don't see any logs that seem to relate to the issue other than the screen size error mentioned above

I see this in Log (Window) output

@ahmelsayed Sorry you are having troubles. I followed your instructions, also added a dotnet restore WebJobs.Scripts.sln before opening VS Code, and didn't have any trouble. Have you tried disabling other extensions to ensure we are the ones throwing an error?

[ahmelsayed]

I did dotnet restore, and disabled all extensions but the WSL extension and C#.

I still see the your 131072x1 screen size is bogus. expect trouble error when trying to switch from WebJobs.Script.Tests.E2E.sln to WebJobs.Script.sln and this error in Log (Window) which I don't know if it's related.

[JoeRobich]

@ahmelsayed I found this related issue in the VSCode repo - https://github.com/Microsoft/vscode/issues/35798

The error is not ours and from the brief look at the OmniSharp log in your gif, it seems that things are loading properly.

[JoeRobich]

The WSL situation makes it look like this open VS Code issue - https://github.com/microsoft/vscode/issues/75932

[ahmelsayed]

Sorry for not getting back to you earlier. The project loads fine when using vscode on Windows, only when accessing it from WSL like in the gif. I'll keep an eye on the issue, though I still don't really understand why it accepts the sln file if it's renamed, but not with its original name.

[victoralvesp]

I think I'm getting the same error in version 1.22.0.

When trying to select a project or solution in a Remote WSL accessing a WSL 2 distro I get:

Command 'OmniSharp: Select Project' resulted in an error (your 131072x1 screen size is bogus. expect trouble ) 

[JoeRobich]

@victoralvesp Sorry you are running into this, but thank you for reporting. I'll reopen and take a look at what we might have missed.

[victoralvesp]

I found a workaround: if you rename the project/solution so it is the first in OmniSharp: Select Project command list and restart omnisharp, it'll start with the correct selected project/solution

[jplane]

Hi... getting the same issue on 1.22.0 with Remote-WSL as @victoralvesp
