The SaveFileDialog in Silverlight lacks a DefaultFileName property, resulting in the user having to enter the file name manually with every file download from a Silverlight application.
This is very annoying and there's a lot of criticism about this, see the Silverlight forum.
My question is: what is the most elegant way to get around this?

Prepare the download and let aspx handle the download for you:

I'll add one suggestion as an anwser myself, which I picked up from the mentioned forum:
Copy the file name to the clipboard so users only have to press Ctrl-V in the dialog.
