문제
I need to work with Google Drive from my UI .NET application. I found that Google uses OAuth 2.0 for authentication. The problem is as far as I understood OAuth sends your token back using HTTP callback, but I don't have a web-server running, it's not a web application at all, does it mean I can't use Google Drive SDK from Windows Forms/Windows Console applications?
