I have tried 3+ versions of the Dev Kit from Pre-release to 0.5.148. Error persists.

@Blad3sy I was not able to reproduce it with a new console project.

Could you share the exact steps that caused you to run into this issue?

@tmeschter FYI as Unable to find the project that contains {path} comes from erroring from querying the project system for the project file with the given file. Are there any issues with certain file path characters?

[Blad3sy]

@WardenGnaw There were no exact steps - this just begun happening one day (specifically Tuesday 5th December 2023). Whenever I create a new project, this error message pops up.

Below is a full video of this bug starting with me reinstalling the c# Dev Kit.

I am however, able to run projects with dotnet run, but I have no automatic error highlighting in files either.

Weird @Blad3sy , here's my repro with your same scenario either (tried with somewhat mirror of your directory). In your profile name are there any special characters at all? What OS locale do you have?

[Blad3sy]

@timheuer The full directory this folder and therefore file is in is: B:\VSCODE Programs\test ( B:\VSCODE Programs\test\Program.cs) B: is a seperate HDD to my main SSD with Windows 10 (Version 22H2 OS Build 19045.3693) installed on it.

Is there any other OS information you need? (I don't really know exactly what to give when you say OS locale, sorry!)

[timheuer]

OS locale

Any language specific settings? Or US-english OS?

[Blad3sy]

UK-English, nothing apart from that.

@Blad3sy From the video, you are adding a new console project via command line, but I don't think adds the project to the solution.

If you expand the Solution Explorer pane, do you see your new console application project listed?

I believe if the project is not in the solution, the project-system can not associate a file to the correct project so it fails. You will either have to add the project to your solution or launch via project, instead of launching via file.

[tmeschter]

I believe if the project is not in the solution, the project-system can not associate a file to the correct project so it fails. You will either have to add the project to your solution or launch via project, instead of launching via file.

That is correct. If the project isn't part of the solution we can't map from files back to projects.

[Blad3sy]

@WardenGnaw Sorry it took me so long to respond,

It is correct that the projects created with dotnet new console are not present in the Solution Explorer (as below)

Running the project with dotnet run does work... I assume this means the problem is that new projects aren't being added to the solution. Is this intentional? This was not happening before about two weeks ago. Is there any way to make the command automatically add the .csproj to the solution?

Thanks.

[kvenkatrajan]

Can you try adding the crpoj to the solution using the Add Existing Project in the context menu? Since the intial release, we do not support adding project reference to solution when creating project via command line automatically - Im not sure how it could have worked in the past.

[kvenkatrajan]

@webreidi - possibly a feature request for future?
