"This is a very common question, raised by people who have no idea what they are doing..." this is a pretty good idea by OriginalGriff.

First thing which comes to mind would be creating an .eml file in temporary directory (you will find .NET classes for that), and call System.Diagnostics.ProcessStart("filename.eml"); if your default mail application understands those files, it will do it.

This is the usual idea, mimic what a system user, non-developer usually does, a person who does not understand how things work. This is "I know just this, don't want to know anything else" approach, can you see it? It will lead nowhere...

But this is really, really sloppy idea, total non-programmer's approach. Better approach would be using mail server immediately. If this is SMPT, then SMPT...

Quite frankly, I've no idea.
The problem is: you are trying to "hack" or master some Interop library. The source code is closed, is that right?
I would seriously consider using some 3rd-party PDF code, open-source. I would not feel comfortable using some Interop with closed code. And by the way, look at Adobe PDFViewer? Awful application, in my view; heavy, slow, inconvenient, highly invasive (always asked the users for update)... How can I trust Adobe after all that?
Just the idea...

Wait a second. On the client? You don't create the temp file, a browser does. You don't have control over it anyway. A user of the browser can call some cleanup...
