Dear Vcampus - colleagues


I'm trying to develop a small web application which write event frames (attribute data)


Windows 2008 R2 Server, VS 2010, .net 4.0


In Visual Studio the application works fine, as soon as I copy it to the IIS I get the following exception:


Description: The application attempted to perform an operation not allowed by the security policy.  To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Cannot write data for Attribute 'Reason' in Event Frame 'Downtime Line3' because the current user does not have WriteData permission.

I googled the error messages, their where a few suggestion about the .net Trust Levels.


But this Trust Level is already set to "Full (internal)" in the iis configuration. (or in the web.config => <trust level="Full" />)
