Remarks
When programming with .NET, this class is hidden. All exceptions that are visible to .NET programming are instead reported as an instance of the System.Exception class, or a specific derivative exception (a standard exception) where the exception type encapsulates a more detailed meaning or scenario for the exception. This is true for first-chance exceptions you encounter while developing, run-time exceptions, and any exceptions that you can handle at the app level using the UnhandledException technique.
For more info on how to handle exceptions using C# or Visual Basic, see Exception handling for in C# or Visual Basic.
For more info on how to handle exceptions using Visual C++ component extensions (C++/CX), see Exceptions (C++/CX).

The Windows Runtime HResult is based on the Windows Error codes model. The Value field combines all the parts of a conventional HRESULT as a single integer (preceding bits, facility, error code). The Windows Runtime does have its own facility, but also uses (and can throw) error codes defined by other facilities.
