C# DLL Message Box

Question

Is it possible to have a C# DLL open a message box? Like in a WinForm:

MessageBox.Show("Message");

I relise that DLL's can't be executed directly but what if it were to be injected into a process to be run, then it could show the message box (if it's possible).

Do you specifically want to use System.Windows.Forms, or do you want it to be a interface IMessageBox and you inject an implementation when you use the Dll? — Meirion Hughes, Mar 11 '13 at 16:56
