Hi, Merlin: The exception indicates that the permission required by the assembly for its minimum grant set is not granted by the CLR security policy. So the assembly couldn't be loaded and the exception is thrown. You could check its minimum request set by looking for .permissionset reqmin in ILDasmto see why your policy didn't grant the assembly those permissions. Here are some refs you may need: 1. Understanding Security Policies http://msdn.microsoft.com/en-us/library/ms154466.aspx 2. The Security Infrastructure of the CLR Provides Evidence, Policy, Permissions, and Enforcement Services http://msdn.microsoft.com/en-us/magazine/cc188939.aspx Please mark the right answer at right time. Thanks, Sam
