Immediate crash on startup (System.Threading.Tasks.Dataflow, Version=6.0.0.0)

[mvonballmo]

I simply ran the project against my solution and it crashed nearly immediately with the following stack trace.

Microsoft.Build.Framework.InternalErrorException: MSB0001: Internal MSBuild Error: Throwing from logger shutdown

Does anyone have any idea what might be wrong? It looks like an assembly-binding issue. I think the DataFlow package should have been delivered with the tool, right?

I have the following runtimes and SDKs installed.

We get the same error. Our project does not use Dataflow.
