[RESOLVED] Compiletime file extention

Hi.
Can anyone please tell me how to give my assembly a custom file extention eg "*.plugin". Im using sharp develop 4 and i dont mind haveing to create a new output type if thats what it takes.
I know i can just rename the files from file.exe/file.dll to file.customext, but this can take some time. Thankyou
