The compressed stack is a compact representation of all the code access security information on the call stack, such as Deny and Assert actions. For example, if a Deny action is two stack frames up from the current frame and there are no other code access security annotations between there and the current frame, the compressed stack records only that information, without having to serialize the entire call stack.

The CompressedStack class is used internally by the SecurityContext class. For example, the SecurityContext.Capture method captures the compressed stack for the current call stack, along with impersonation and culture information. The SecurityContext class is used in turn by the ExecutionContext class to flow context across threads, for example when scheduling thread pool tasks.

This class is not used in ordinary application programming.
