Could not load file or assembly 'Microsoft.Extensions.Configuration.Abstractions' after upgrading ASP.NET to 1.1 from 1.0.1

[DOMZE]

Hello,

I've read through the following 2 (issue 1, issue 2) issues and tried the fixes:
Clearing my nuget global-packages cache
Deleting my bin folder along with the obj folder
Deleting the .lock files

I copied all my dependencies (except my framework dependencies) from my project.json to a brand new ASP.NET Core project and setting the project to a net461 project.
The project compiled and ran properly.

Here is my project.json:

  },,
  "runtimeOptions": {
    "configProperties": {
      "System.GC.Server": true
    }
  }
}

Any idea on how to resolve this?
I reverted to 1.0.1 and everything works as expected

Friday blues... was referencing another project whose versions were not the same.
For info, look into the file project.fragment.lock.json to see all your references

Thanks!
