Description

I'm having trouble upgrading a web application running under medium trust from 2.9.4 to 3.0.3. Code that previously worked now throws a SecurityException.

[SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.]
