First of all, you don't explain what do you mean by application name. As the application processing your hooked message can be anything (no only .NET assembly), there is no such concept. Too different application can carry the same executable file name, identical text of the windows header, and still be the different, so whatever you do, there in no 100% certain identification.

What you can get is the information on the application's main window handle and hence its text. First of all, you need to obtain some native Windows API methods using P/Invoke.
You can call Windows API GetWindow with parameter GW_OWNER and GetParent to find out the main application windows. (You always use GetWindowText to find out the text of the windows header, but as I say, it is not a reliably unique identifier.)

Then you can list all processes using the class System.Diagnostics.Process and identify the process showing the windows in question by its HWND. This way you can obtain all available process information on the process processing your hook.
