BigRock Hosting error: The application attempted to perform an operation not allowed by the security policy

Question

My application works perfectly on my local machine. But when I tried to publish it on BigRock Shared Hosting I get following error message-

Security 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

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.ReflectionPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Stack Trace:

How can I resolve this?

Answer 1

An error indicates that either your website is not running under its own application pool Or your website requires the trust level that your web host don't allow. For instance, your application requires Full trust level to run and your web host don't allow to run applications under Full trust level.
