Before you call the Demand method, you must set the current application domain's principal policy to the enumeration value WindowsPrincipal. By default, the principal policy is set to UnauthenticatedPrincipal. If you do not set the principal policy to WindowsPrincipal, a demand for principal permission will fail. You should execute the following code before you demand the principal permission: AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal). |
