Shutting down ArcGIS .NET applications
To help unload COM references in .NET applications, the AOUninitialize class
provides the static (shared in VB.NET) function Shutdown. This class is part of
the ESRI.ArcGIS.Utility.COMSupport namespace in the ESRI.ArcGIS.Utility.dll
assembly.
For more information on shutting down ArcGIS .NET applications, see ‘Releasing
COM References’ in this chapter.
[C#]
ESRI.ArcGIS.Utility.COMSupport.AOUninitialize.Shutdown();
[Visual Basic .NET]
