Create New Project from Existing Code Wizard If you have an application that does not include project or solution files, such as an application that you obtained from an online source, you can easily create a Visual Studio project from the existing code files. A project can be created from any one of the following types of code files: Visual Basic, Visual C++, Visual C#, or Visual J#. Using the wizard accessible from the File New menu, you specify the details of the existing code files that will be added to the project and the application that will be created when you build the project. The wizard lets you specify which file types you want to add to your project, and from which locations and sub-folders. For Visual C++ applications you have additional options for setting the project type and adding support for ATL, MFC, and CLR, as well as setting the debug configuration and, if you wish, using an external command-line build system. The project is created on your computer and all relevant files are added to the project.
