Branching in VS 2010 with TFS loses NuGet package references

Question

I am using Visual Studio 2010 with Team Foundation Server 2010. I have created a root for a project which uses AutoMapper and EntityFramework which I installed for the solution using NuGet package manager.

When I branch from the root the resulting branch has a yellow warning triangle in the references section for the AutoMapper and EntityFramework. I have tried uninistalling the packages and then reinstalling but nothing allows me to include these references and build the solution. The only message I get is that the package aready exists.

All suggestions gratefully received.

Answer 1

I have solved the problem. The root solution was a created from existing projects from another source and there were some NuGet package references in the packages.config files in the project folders. The steps were:

• Delete the packages folder (if it has been copied over) from the root of the solution
• delete any NuGet references to the packages from the solution file (.sln)
• delete any NuGet references from the packages.config files
• Using Manage NuGet Packages for the solution to uninstall any packages
• Reinstall from the solution level

And then all was fine.
