We aren't compatible with .NET Framework.

Actually the fact that this option showed up is a tooling issue.

[mitchdenny]

OK so this works in VS, because in VS we build the project and then we rely on DCP to call VS to start the project (which it does happily). In the case of dotnet run, DCP launches the project which triggers a build via dotnet run which fails on the .NET Framework-based project.

Right, this isn't supported. It's not possible to run .NET Framework projects with .NET run, this only works in visual studio.
