cant run this project in VS2015 update 2 with ASP core addition

This runs in the cloud foundry using the core build pack 

   https://github.com/cloudfoundry-community/dotnet-core-buildpack

But i load the project using VS2015 udpate 2 with ASP core addition and it builds.

But i cannot run it using IISExpress and the IDE.

Must i do something special to VS2015 to make it run the same as CF version?

Thanks,
