Permissions in the common language runtime are objects that describe sets of operations that can be secured for specified resources. A permission object describes operations or access that is subject to security control; it does not represent access or a right to perform operations. Permissions are used by both application code and the .NET Framework security system in the following ways.
Code requests the permissions it needs in order to run.
The security system policy grants permissions to code in order for it to run.
Code demands that calling code has a permission.
Code overrides the security stack using assert/deny/permit-only.
If you write a new permission, you must implement this interface in your class.
