Visual Studio Form in unity3d

Hi, I want create a form with Visual Studio 2010, and i would to use it in unity…How I do it? how I can import the dll that use VS in unity? thank you…

Not going to happen, Unity uses mono which is a re-implementation of the .net framework(most of it), the required classes and such don’t exist and that doesn’t extend to other OS’s that mono works on as "WIN"form/WPF is a windows only framework, though the mono project has other similar frameworks…

I want to create an interactive menu with a music loading bar … how can I do? otherwise I import a file created with adobe flash?
