Thanks - will investigate shortly! Can you post the output of dotnet --info?

The command could not be loaded, possibly because:
  * You intended to execute a .NET application:
      The application '--version' does not exist.
  * You intended to execute a .NET SDK command:
      A compatible .NET SDK was not found.

Requested SDK version: 8.0.100

Same here (Windows11/WSL2, Dev Containers)

[tintoy]

Just for now (so we don't affect anyone else while we investigate), I have rolled back to the previous version (v0.4.9) by publishing it as v0.5.1. The new package should appear in the gallery soon.

[tintoy]

@AdamCoulterOz and @glen-84 - it seems to indicate that there are no .NET SDKs installed on your system, is that correct? Or is this just a result of running it from that location?

If you remove the path prefix from the dotnet command, do you get different output?

[tintoy]

@DoctorKrolic - from the output above, it seems that the .NET runtime acquired via the vscode-dotnet-runtime extension is isolated and does not see any of the .NET SDKs installed the regular way...

Is this the behaviour that you've seen while working with it?

[tintoy]

@Martin521 - do you have the .NET SDK installed your dev container?

[glen-84]

@AdamCoulterOz and @glen-84 - it seems to indicate that there are no .NET SDKs installed on your system, is that correct? Or is this just a result of running it from that location?

The latter. (I have SDKs installed)

If you remove the path prefix from the dotnet command, do you get different output?

Yes.

[tintoy]

@glen-84 - ok, thanks, it sounds like we need to find a way to locate the global dotnet executable and associated SDKs after the extension has been loaded by the isolated runtime.

[glen-84]

Also, not sure why it installs .NET 6.

[tintoy]

Also, not sure why it installs .NET 6.

I think that's because it's the version that the language server was built against.

[tintoy]

@DoctorKrolic - this might do the trick:

[Martin521]

@Martin521 - do you have the .NET SDK installed your dev container?

Yes, 8.0.0-rc.1.23419.4
(Config here)

[AdamCoulterOz]

I've got 8.0.100 installed

[DoctorKrolic]

I made a PR which sould resolve this. I described what exactly happened and why we were not able to catch this during development there. In the meantime I apologize for the inconvenience. There are only 2 of us maintaining the extension, so we don't have enough resources to cover all cases when testing. Thanks for patience and the contribution, your logs and other info were pretty useful!

[tintoy]

Yeah, sorry I should have been more thorough when testing the new changes; I don’t have a Mac anymore but I normally try to smoke-test each release in WSL and dev containers before publishing.

(I’ve spent too much time this month fighting kops and terraform so I’ve been a little distracted 😂)

[Martin521]

Thanks to both of you for providing this great extension and for the quick reaction!
