VS Project Metadata missing?

Screenshot attached.  When I try to create a Unit Test project that references an integration project I'm working on that was generated by Integration Studio, I get this error: "A reference to <Project Name> could not be added.  No metadata was found.".

I want to be able to make a Unit Testing project in C# that references the project.  Am I doing something wrong?
Hi Joshua,

That happens because you never compiled the RunnerCore project.
Just right click on RunnerCore -> Build.
And you will be able to add the reference on your Unit Test project after that.

It worked.  Thank you!
