Why Resharper not detect unused references in empty MSVS 2015 console app?

Question

If you try to create empty console app in MSVS 2013 and remove unused references, then only two of them remain: System and System.Core.

But if you preform same task in new MSVS 2015 Community (14.0.23107.0) then nothing except Microsoft.CSharp would be removed:

I think that it is quite strange behavior. All that (actually unused) references used in some temp code file called .NETFramework,Version=v4.6.AssemblyAttributes.cs:

And it is fine if you remove unused references manually - project builds without problems.

The question is: what purpose of that temporary auto-generated file and why it has so many dependencies? It hasn't actually, that is why I suppose that it is bug or something...

Answer 1

ReSharper Team will investigate it https://youtrack.jetbrains.com/issue/RSRP-446156

Answer 2

I was having this problem too. I deleted that temp file and generally cleaned up my temp folder. Then things worked as you'd expect.
