File Duplication in Forms and Displays

When forms or displays that were created in the Forms Designer are duplicated, the files in the project folder (in Windows Explorer) are also duplicated.

The duplicated files include the standard project files, as well as any additional files that may have been created if the form or display was edited in Visual Studio. Examples of files that will be duplicated are .sln, .suo, and files created by third party tools.

If you do not want to keep these files with the duplicated form/display, manually delete them from disk. The next time the project is saved, the files will no longer be saved with the duplicate. The.sln file will still point to the original project name, and therefore should be deleted from disk. These files will be recreated the next time the .csproj or .vbproj file is opened in Visual Studio.
