FIX: A method does not throw a custom exception type in the .NET Framework 2.0

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.

To work around this problem, use one of the following methods:

• Add a non-primitive type parameter to the method.
• Call the method by using another method that meets the following requirements:
  • This method is implemented in the class that is derived from the ServicedComponent class.
  • This method is not defined in the custom interface.
• Do not use the method that is inherited from the custom interface. Instead, implement a method in the class that is derived from the ServicedComponent class.
