[gonzalorf]

Any news about this? I'm having the same problem.

[georg138]

I had the same issue. After installing the current version of .NET 6 (6.0.31) to get GitExtensions working, it works. Before, I already had 6.0.30 installed (alongside with .NET 8.0.6 and others)

[mumiman]

I try bwulms 's solution [https://github.com//issues/1157] and it's work.
"Solved by removing dotnet completely by deleting /usr/local/share/dotnet and then installing only the arm version of the dotnet 8 sdk."

[NogginBops]

I'm also having the same issue. I tried reinstalling dotnet (I only have 8.0 installed now). This is an intel mac.
Here is the log I'm getting:

There are two users on the system and the logged-in user is not the "main" user of the system.

The .sln file used can be found here: https://github.com/NogginBops/opentk/blob/4d8ecc296f07b3ce47199a852369e92a1f036adf/OpenTK.sln
This solution works fine in Visual Studio on windows and using the C# dev kit on linux.

I only got this issue recently and the C# dev kit has historically been working decently until today.

[NogginBops]

Restarting the computer fixed my issue, at least for now.

[Michael-Eng]

Since most of the original issues are stale (about .NET6 and we've moved to .NET8) and the most recent comments from @NogginBops has been resolved, I'm going to close this out.

If you're still having issues getting started please log a new issue so we can ask/review your logs.
