I have a problem with visual studio and nuget package manger
I was running very good when suddenly the project stopped to compile telling me that the ApplicationDbContext should derive from DbContext or something like that, i couldn't see the problem so i cleaned my solution rebuilt the project it compiled but had stupid runtime erros so I searched stackoverflow and the web And I found out it was a reference error in the first place so I removed the bin folder as described here in this question
higher version than the referenced assembly
then it went all bad i tried to remove all the references and re-install them manually but nuget PMC kept telling me that my project already had a reference to that assembly,, I closed Visual Studio re-cleaned the project and done that once again with no results!
so the question here would be how to re-install the latest version of everything to be compatible with asp.net MVC 5.1 without getting a message telling me that my project has a reference to those assemblies nonsense !
