Hi,
Thanks for letting me know about this. I had made a small change that I did not realize was an issue under medium trust. I tested on my local machine this morning with medium trust and was able to produce the error and fix the problem with a very small change.
I've patched the 2.3.4.2 mssql and sqlazure files with the fix. If you download the package again, the only file that changed is /bin/mojoPortal.Web.dll
Hope it helps,
Joe
