Could not get dependencies for project reference

After trying many things, I realized something. The error was never going away, no matter what I did to clear the builds and such. I closed and reopened the solution and it went away.

When you get the error message "Could not get dependencies for project reference", one of the possible causes could be that you are referencing another project in your solution which has a Target framework not compatible with the target framework of the referencing project.

You can see the target framework specified for a project by going to the project properties and selecting the Application tab on the left.

I'm writing this because it happened to me, I was referencing a project with Target framework 4.0 from a project with target framework 3.5.
