Copying winforms between projects in Visual Studio

What is the best way to copy or cut/paste a form from one project to another project within a Solution in Visual Studio?

Whenever I try it, using the solution explorer (drag and drop or right clicking cut and paste), it only copies the underlying C# code and not the necessary ‘bits and pieces’ that help you visualise the form via the form designer.


  1. Copy the three files, .cs, .designer, resx to the target solution folder.
  2. In the target project, select Add existing item and add the designer file first.
  3. Modify the Namespace attribute. The .cs file should come in as well.
  4. Modify the namespace in the .cs file.
  5. Add the resx file using Add existing item.
