Remarks

Important noteImportant

Starting with the .NET Framework version 4, identity permissions are not used.

   In the .NET Framework versions 1.0 and 1.1, identity permissions cannot have an Unrestricted permission state value. Starting with the .NET Framework version 2.0, identity permissions can have any permission state value. This means that in 2.0 and later versions, identity permissions have the same behavior as permissions that implement the IUnrestrictedPermission interface. That is, a demand for an identity always succeeds, regardless of the identity of the assembly, if the assembly has been granted full trust.

In the .NET Framework versions 1.0 and 1.1, demands on the identity permissions are effective, even when the calling assembly is fully trusted. That is, although the calling assembly has full trust, a demand for an identity permission fails if the assembly does not meet the demanded criteria. Starting with the .NET Framework version 2.0, demands for identity permissions are ineffective if the calling assembly has full trust. This assures consistency for all permissions, eliminating the treatment of identity permissions as a special case.

NoteNote

By default, code access security does not check for Publisher evidence. Unless your computer has a custom code group based on the PublisherMembershipCondition class, you can improve performance by bypassing Authenticode signature verification. This is accomplished by configuring the runtime to not provide Publisher evidence for code access security. For more information about how to configure this option and which applications can use it, see the <generatePublisherEvidence> element.
