When opening a project with:

usingvarworkspace=MSBuildWorkspace.Create();returnawaitworkspace.OpenProjectAsync(projectFilePath,cancellationToken:cancellationToken);

if the app is trying to open a project targeting a SDK > at the app running, the following exception is thrown:

Microsoft.CodeAnalysis.MSBuild.RemoteInvocationException: An exception of type System.InvalidOperationException was
thrown: Failed to find all versions of .NET Core MSBuild. Call to hostfxr_resolve_sdk2. There may be more details in

It would be nice to improve the message with something along the lines of Ensure the target framework version of your app is equal or superior to the SDK version of the project to load
