This happens when the dotnet sdk isn't available in PATH.

There was a problem hiding this comment.
we could just return a null I think
however, a better question is if we should allow to start without dotnet on the path at all.
There would be other things that will fail without it e.g. auto restore or test adapter

I've been getting errors like:
{"Event":"log","Body":{"LogLevel":"ERROR","Name":"OmniSharp.MSBuild.ProjectLoadListener","Message":"Unexpected exception got thrown from project load listener: System.NullReferenceException: Object reference not set to an instance of an object\n at OmniSharp.MSBuild.ProjectLoadListener.GetSdkVersion (OmniSharp.MSBuild.Notification.ProjectLoadedEventArgs args) [0x0000b] in <7e6cb753aca94549b693616e0e7d1016>:0 \n at OmniSharp.MSBuild.ProjectLoadListener.ProjectLoaded (OmniSharp.MSBuild.Notification.ProjectLoadedEventArgs args) [0x0001a] in <7e6cb753aca94549b693616e0e7d1016>:0 "},"Seq":137,"Type":"event"}This happens when
dotnetisn't available in PATH. Omnisharp runsdotnet --infoand if it fails,SdkVersionends up null.My change is a bit hacky. Perhaps it would be better to propagate the null through to
ProjectConfigurationMessage.SdkVersion? That seems to be the only place it's used, but it might be a breaking protocol change.
