title: In a C# project, how can I refer to a project written in C++ and compiled with /clr?
body: <p>I have a fairly large project written in unmanaged C++ and generating a DLL.  I would like to be able to use the DLL in a .Net project (in this case, just a bare-bones WinForm application).  I rebuilt the DLL with /clr set.  It built successfully.  In my WinForm project, I selected Add Reference, selected the Project tab, and selected the DLL project.  It was successfully added as a reference in my WinForm project.  However, I am having trouble using the DLL.  I want to add a using directive for it, but I do not know what name the DLL has.  I tried using the same name as the file, but it didn't work.  How do I find out what its name is for use in a using directive?</p>
  
  <p>Thanks very much!</p>
