Conditional APTCA
You can allow an assembly to be called by partially trusted code by applying the System.Security.AllowPartiallyTrustedCallers attribute at the assembly level. This can be accomplished as follows:
Imports System.Security<Assembly: AllowPartiallyTrustedCallers()>
Without this attribute, only full-trusted code can call the assembly. Different from versions prior to 4.0, in the .NET Framework 4.x this attribute no longer requires an assembly to be signed with a strong name, and its presence involves all the security functions present in the code in the security checks.
