I have a problem with references in my Visual Studio 2012 project. Does anyone have an idea how to solve this? I already downloaded some updates of the framework and tried to update some packages but still I have this error. The problem I think is in the versions with which the project was created.
If you have validated that the references are not correct you could validate nuget by means of Tools -> Options
You could also update nuget by% Tools -> Extension Manager
You may update it to update your libraries
It also validates if you have the package folder at the .sln level, and if there is content inside it, if you delete what you have inside when compiling nuget you should download the libraries again
You may have to check the options that allow you to automatically download the packages
