Enables an application to "manually" report faults to Microsoft. Although you can use this function to report application crashes, Microsoft recommends that applications not handle fatal errors directly but instead rely on the crash reporting capability provided by the operating system.

The ref modifier or the [MarshalAs(LPStruct)] attribute are required on the guid parameter; otherwise it is marshaled incorrectly and the call will fail with an access violation.

The Windows API documentation states that this function automatically calls AddRef on the resulting instance before returning. The .Net framework seems aware of this at some level, as the object is freed correctly with a single call to Marshal.ReleaseComObject()
