tfs2012 - Team foundation server:error when I click on the solution file in source control explorer -

There is an error message that I'm getting "resolved in the solution project. This will not affect the project done. It is strongly recommended that you reload all the projects before contuning. "

What does this mean? How can I handle it?

Right-click on the project loaded after the solution load and click to load the project If there is an error in loading the project, the probability of that error will be more descriptive as the project is not loading. This may be because you have not received a local copy of the files of that project.
