Failure adding NuGet ref to EF.Relational.FunctionalTests from release branch

[ErikEJ]

Using EntityFramework.Relational.FunctionalTests.7.0.0-beta6-13815 from the MyGet release feed at https://www.myget.org/gallery/aspnetrelease with Visual Studio 2015 RTM on brand new VM.
Getting error when adding to test project targeting .NET 4.6:

Failed to add reference to 'System.Collections.Concurrent'

(Can add EF.Relational reference to Projects targeting .NET 4.5)

This is blocking me from being able to build a beta 6 release of the SQLCE EF provider (well, I can build the product DLLs, but not run any tests 👎

[ErikEJ]

Possibly related to #2457 (but I am using a RTM Azure image)

[ErikEJ]

Removing the project reference to the product DLL, and removing all previuos NuGet references seems to have "fixed" it

[bricelam]

Yeah, I saw something similar. I need to dig into it; I think one of our dependencies is violating aspnet/dnx#2031.

@ErikEJ anything outstanding from your side here?

[ErikEJ]

Yes, as it makes upgrading based on daily builds very cumbersome, error prone and time consuming

[bricelam]

Found it. This is an issue with the Microsoft.Framework.Logging package.

😄 Fixed now, thanks a lot!
