Happens in a console app too. Note I'm in the codespaces environment.

This feels funny to me - that .NET SDK install path seems very non-standard. I'm wondering if you have some of the new ubuntu packages mixed up with the MS-official packages here.

[TanayParikh]

This was within a relatively clean GitHub codespaces environment. Repro can be achieved using a new codespaces env in the https://github.com/dotnet/aspnetcore repo.

[TanayParikh]

Oh and I installed .NET 7 using the dotnetinstall shell script.

[marcpopMSFT]

Definitely think it's something with your install. From the code, this is where it's failing:
https://github.com/dotnet/sdk/blob/release/7.0.1xx/src/Cli/dotnet/CommonOptions.cs#L245

So the call to GetDotnetExeDirectory() is finding the 6.0 path for dotnet root path. From that method, it's gets the directory of the current process (dotnet in this case) and then has a bunch fallbacks for finding the rootpath
dotnetRootPath = Path.GetFileName(dotnetRootPath).Contains("dotnet") || Path.GetFileName(dotnetRootPath).Contains("x64") || Path.GetFileName(dotnetRootPath).Equals("d") ? dotnetRootPath : Path.Combine(dotnetRootPath, "dotnet");

Any idea which of these is being picked on your box as you know your directory structure? Also, is this still happening?
