Asp.Net Core 1.0 Error "Failed to make the following project runnable"

Steps to reproduce

Have library in .NET 4.5 that uses a third party library that has an assembly name as XXX.v15.4.dll. The project builds properly, but when trying to run the project it looks for “XXX.v15.4, version=15.4.0.0, culture=neutral, publickeytoken=b881323kd82k.dll”

Note that it works in RC2 without a problem.

Expected behavior

It should look for “XXX.v15.4.dll”

Actual behavior

An error message comes up with the following: Failed to make the following project runnable: PROJECT(.NETFramework,Version=v4.6.1) reason: Could not find file ‘C:\Projects\MainBranch\BlahBlah\bin\Debug\XX.v15.4, version=15.4.0.0, culture=neutral, publickeytoken=b881323kd82k.dll’.

I solved this issue by doing to things;

1. delete the app.config from the root of the project.
2. delete obj and bin folder

Maybe this can provide a hint to the deeper issue?

Any further progress on this? It looks like this may be the same thing that is blocking our project because we are referencing a regular C# library in order to utilize web references…
