Guidelines for using method permission requests in C#

• Use SecurityAction.PermitOnly declarations to limit the permissions available to each method.
• Use Security.Deny declarations to further refine the permissions available to each method.
• Use CodeAccessPermissoin.Assert when you want to allow partially trusted code to call a method that requires permissions the caller might lack.
• Use CodeAccessPermission.PermitOnly to imperatively reduce permissions when a section of a method requires fewer permissions than the rest of the method.
• Use CodeAccessPermission.Demand only when your assembly implements customized functionality that does not rely on functionality built into the .Net Framework, such as calls to unmanaged code.
