TeamFoundationSecurityNamespace.CheckPermission Method (TeamFoundationRequestContext, String, Int32, Boolean, PermissionEvaluationCallback)

First checks to see whether the request context making the call is a SystemRequestContext and if it is, it returns immediately. Next, it queries the underlying permission store to determine whether the requestContext.UserContext has the requested permissions for this token. If alwaysAllowAdministrators is true and the UserContext is an admin on this server, the user will have permissions regardless of what the permission evaluation says. If the UserContext does not have the requestedPermissions, a SecurityAccessException will be thrown.
