How to easily duplicate a Windows Form in Visual Studio?

Question

How can I easily duplicate a C#/VB Form in Visual Studio? If I copy & paste in the Solution Explorer, it uses the same class internally and gets messed up. How do you do it?

Answer 1

1. Add a sub-folder to your project.
2. Right-click on the sub-folder, and click Add Existing Item.
3. Browse to the form you want to copy, and select its .cs file. This will duplicate the original form (partial and resx and all) in the sub-folder. The name will not conflict with the original, because the sub-folder will be included in its namespace.
4. Right-click on the .cs file, click Refactor | Rename and enter the new name. This will also rename the partial and the resx for you.

I'm generally averse to methods of doing this that involve opening up the files in notepad or whatever, since I always think a common task like this should have a built-in way of doing it in Visual Studio. In this case, there is.
