I've written an upload web service for transfering files to a web server (mostly as something to play with), and tested the WCF service against a standard WinForms app - This worked as expected transferring large files w/o issues. I then added a simple SL client (openfile dialog + one label!) and tried the same test; This gave me a 'System.ExecutionEngineException' exception, and when I looked at the transferred file size I managed to get 6mb regardless of type of file or file size. Files under 6mb transferred with no issue.

I kinda think I'm missing something obvious, but can't spot it. Anyone had something similar, or can offer any suggestions?

You can change it to a larger number 4) If you allow file size more than 30 MB to be uploaded, then you might hit another limit again. Then you need to break your file into smaller chunks then pass them back one chunk at a time. If you need this. See this thread. Save the Client Config file Now you should be upload a file up to 4MB.
