How to: Create a Project from Existing Code Files
You can create a Visual Studio project from an existing app—for example, an app that you obtained from an online source. Project and solution files are created on your computer and the other relevant files are added. A project can be created from Visual C++, Visual Basic, or Visual C# code files.
We recommend that you determine the trustworthiness of existing code files before you import them into Visual Studio, because Visual Studio will execute some of the code in a fully trusted process when you open the newly created project.
To create a project from existing code files
On the menu bar, choose File, New, Project From Existing Code.
The Create New Project from Existing Code Files wizard opens.
In the wizard, specify details about the existing code files that will be added to the project, and about the app that you will build.
