+Exception handling is very important in the .NET Framework. In every place where an error can occur, you should provide exception handling. If you don't provide it, at runtime the application will crash without details about the error.
+There are also a few application wide handlers you can install (and your should use them):
+  * [[https://docs.microsoft.com/en-us/dotnet/api/system.appdomain.unhandledexception?|AppDomain.UnhandledException]]: handles otherwise unhandled exceptions
+  * [[https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.application.threadexception|Application.ThreadException]]: handles exceptions in Windows Forms applications
+  * [[https://docs.microsoft.com/en-us/dotnet/api/system.windows.application.dispatcherunhandledexception|Application.DispatcherUnhandledException]]: handles exceptions in the WPF GUI
+You can find a note about these also in the X# forum: [[https://www.xsharp.info/forum/public-vo-vn/310-suggestions-for-conversion-vo-programs-using-vo-gui-classes?start=10|Handling exceptions by Paul Piko]]
+There are several publicily available exception handlers like [[https://logging.apache.org/log4net/|Apache log4net]] or [[https://msdn.microsoft.com/en-us/library/ff649552.aspx|Exception Handling Application Block]] in the Enterprise Library.
