APPLIES TO


 * Microsoft .NET Framework 2.0

SYMPTOMS
Consider the following scenario:
 * In the Microsoft .NET Framework 2.0, a class is derived from the ServicedComponent class.
 * This class implements a method that is inherited from a custom interface.
 * This method is used to throw a custom exception type that is derived from the ApplicationException exception type.
 * This method does not use non-primitive type parameters.

In this scenario, if a managed client application calls this method by using a reference to the custom interface, this method does not throw a custom exception type that is derived from the ApplicationException exception type. Instead, this method incorrectly throws the ApplicationException exception type.
