Remarks
Types or members that are marked with the SecuritySafeCriticalAttribute attribute can be accessed by types and members that are marked with the SecurityTransparentAttribute attribute or that are security-transparent by default. Code that is marked with the SecuritySafeCriticalAttribute must ensure that all inputs and outputs to and from security-critical code comply with security requirements. This code is subjected to a rigorous security audit to ensure that it can be used safely in a secure execution environment. The SecuritySafeCriticalAttribute is ignored when it is applied in user assemblies, that is, in assemblies that are not installed with the Silverlight library assemblies and that are not signed with a specific strong-name key.
