Projects available within a workspace are reusable. It means, you can use the same project in any number of solutions that you create in a workspace. You can use an existing project irrespective of whether you or some other developer in the team created it. Reusing projects minimizes the development effort.

To reuse a project, you have to add it to the solution you are creating.

1. On the toolbar of Workspace Documents (Explorer), click and select the solution to which you want to add a project. The selected solution and its contents appear in the workspace.
   
2. Choose one of the following ways to add a project:
   
   • 1. Right-click the <solution> and select Add > Existing Projects. The Solution window appears displaying the list of projects that you can add to the solution.

        
        Note: The list does not display the projects that are already a part of the current solution.

     2. Select the check box next to the project(s) that you want to add and click Finish.
        
   • 1. On the toolbar of Workspace Documents (Explorer), click > Project List. The Project window appears displaying the list of projects available in the workspace.
     2. Select the check box next to the project(s) that you want to add. The icon on the toolbar of the Project window is enabled.
     3. Click (Add to current solution). The window displaying the list of projects closes.
        The selected projects are added to the solution you are developing. You may modify the existing contents of that project or add new documents to it.
