Add Existing Project Command

Adds an existing project to the current solution.

File.AddExistingProject filename


Optional. The full path and project name, with extension, of the project to add to the solution.

If the filename argument includes spaces, it must be enclosed in quotation marks.

If no filename is specified, the command will open the file dialog so that user can pick a project.

Auto completion tries to locate the correct path and file name as you type.

This example adds the Visual Basic project, TestProject1, to the current solution.

>File.AddExistingProject "c:\visual studio projects\TestProject1.vbproj"
