Although a project must reside in a solution, you can create a solution that has no projects.

To create an empty solution

1. On the File menu, click New and then click New Project.
2. In the left pane, select Installed, select Other Project Types, and then select Visual Studio Solutions from the expanded list.
3. In the middle pane, select Blank Solution.
4. Set the Name and Location values for your solution, then click OK.

After you create an empty solution, you can add new or existing projects or items to it by clicking Add New Item or Add Existing Item on the Project menu.
