I\'m working in TFS with my team for project and the problem occurs when I\'m trying to make new modeling project for my classes, it doesn\'t show up in pending changes.
It looks like your solution binding is broken. Either click yes on the question to bind your solution to source control, this is information that must be stored in the solution file and while Visual Studio does see that the folder is mapped to source control, it also sees that your solution isn't (did you check the add solution to source control checkbox when you created it?)
Optionally try opening file -> Source Control -> (optionally) Advanced -> Manage Source Control. You can select project in your solution individually and then click the bind button on the toolbar to bind them to sourcecontrol manually.
