Solution explorer is unable to load a netstandard2.0 project

[kblok]

Type: Bug

The solution explorer says that "A compatible .NET SDK was not found" but if I click "Build solution" it is able to build a solution. I also get a "Projects: x 8" error at the bottom with no clear explanation from there.

@kblok this is working for me. Can you add output of your dotnet --info?

[kblok]

@timheuer sure! For the record. My main IDE is VS For Mac, and it's working as expected.

Ok, will have to see if someone on the team can repro in this environment (can't imagine it would be arm-specific). Just tried on my mac as well and I can see it fine. Another you can try to confirm it is not just yours is https://github.com/timheuer/alexa-skills-dotnet

[kblok]

I'm getting the same on that repo :/

[timheuer]

Thanks for confirming -- will get it assigned.

Hi @kblok, I have some follow-up questions for you:

1. Are you still experiencing this issue?
2. If so, would you be willing to try removing the Homebrew installation of the SDK and installing the latest .NET 7.0 SDK (currently 7.0.400) from https://dotnet.microsoft.com/en-us/download/dotnet/7.0? We've had other reports of issues with the Homebrew install (discussed in #120 among others).

[kblok]

Removing dotnet from brew worked! Thank you!

[tmeschter]

To fully close the loop on this, there are a couple of things that may be going on:

1. The version of the .NET SDK installed by Homebrew is too old. In this case 7.0.100 was installed, but C# Dev Kit really wants 7.0.203 or newer. However, I wouldn't expect the project to be completely broken by this, and I haven't seen the "A compatible .NET SDK was not found" message resulting from this.
2. C# Dev Kit (or some part of it) is not able to locate the SDK at the path used by Homebrew. This seems a more likely explanation to me, and improving the detection of SDKs (however they are installed) is something we are working on.

@kblok I'm glad this is working for you now. If this behavior happens again please open a new issue. Thank you!
