Exceptions

The C# clients detects a number of errors. This is especially important when the framework is used for untyped applications as there are more possibilities for runtime errors. The framework has three exception classes.

WSManException

For C# implementations, this class inherits from WebException. This exception represents a WS-Management error, and contains the WS-Management fault information.

These exceptions, along with others that are defined in the C# standard library, are thrown whenever an error occurs.
