I need help regarding file uploading in sandboxed solution. In a thread in this portal somebody gave the following link as a solution to this problem:
but this is also not working for me. The webart is throwing exception:
Unhandled exception was thrown by the sandboxed code wrapper's Execute method in the partial trust app domain: An unexpected error has occurred.
Can you please guide me how can I beat this? I have been pulling my hair out for days, your help will be much appreciated.
