Answer 1

I had this once, caused by a broken .targets import. Check if you accidentally enabled nuget package restore (which includes a .targets file) and then deleted the .nuget directory.

Answer 2

I had similar issue. The solution, which worked for me was to pop the nuget package manager for the solution and refresh the packages.

Another case involved missing packages and nuget package manager for the solution showed updates and dependencies, which needed to be installed and this was the fix.

Another case was exactly as pointed above - delete packages folder fixed it.

Editing manually the project is an option, but there is a chance if you poke where you are not supposed to, your project may not open. If you can, avoid doing that is my opinion.

Answer 3

In the root directory of the solution, delete everything inside of /packages/ folder, then do a re-build.

Answer 4

Unload project, then edit project

look for the following and delete.

This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them. For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.

I also experienced exactly this in VS2015 on a solution with around 10 projects. Only one project - the main MVC project - was affected and it lost all references including to the standard .NET assemblies.

The problem was in my web.config. I had commented some lines, resulting in an invalid xml-file.

I've just experienced exactly this in VS2015 on a solution with around 20 projects. Only one project was affected and it lost all references including to the standard .NET assemblies.

The only way I could resolve was to switch to a different GIT branch and then back, this cleaned up the issue and it is all now working.
