WP7 – IsolatedStorageExceptions

So I had blogged a couple weeks ago how I was getting non-descript IsolatedStorageExceptions.  Not knowing the reason for the exception is super irritating.  As you can see from the exception details there is no indication of the root cause, only that the “operation” is not permitted.


I found you can use the immediate window to get more details about the exception:


As you can see I made the call manually in the immediate window and am told that the directory hasn’t been created yet.  Hope this helps someone else.
