I\'m just getting to grips with TFS 2010 (never had any luck with TFS 2008) and I\'m trying to add my first solution into TFS. However I am getting the following warning mes
The following issue can sympomatically manifest the error you reported. Remember, referenced assemblies need not be in any specific location in either TFS or in the file system of your workstation.
An underlying problem is that some types of projects default to the "Client" version of the targeted .NET Framework. The Client versions strip out assemblies that are usually not used in deployable projects. Furthermore, any assembly your project references must also not reference assemblies omitted by the Client profile.
Simply change the Target framework setting of your project to the full framework version.

For me it was like this that I tried to add the solution from another location already. I then had to clean the workspace which was created for the other location.
For Visual Studio 2013 you can find the workspace settings under:
File -> Source Control -> Advanced -> Workspaces...
Manage Workspaces
dialog select your workspace you work withEdit...
.Edit Workspace <yourworkspacename>
dialogTry to add the solution again.
As described in this Visual Studio forum post (link below), the basic issue is that a project in the solution is outside of the sub-tree that the solution itself is in. This can possibly lead to problems if another user maps the different subtrees differently in his workspaces than the user that is checking in. The cross-tree references will no longer work. The dialog is only a warning, but can be continued if you know your team doesn't split up the code tree with complex workspace mappings.

Your solution folder structure should resemble:
Solution Root folder
├── .sln solution file
│
├── Project1 folder
│ └── Project1.csproj (or .vbproj)
│
├── Project2 folder
│ └── Project2.csproj (or .vbproj)
