Calling a ArcGIS plugin from managed code via late binding

In the sandbox a demo project has been added that calls an ARCGIS plugin via late binding

please refer to delft-tools\sandbox\ArcGisProjects\DesktopExtensions 

The relevant code is

public class ArcViewOnlyExtension : IExtension, IExtensionConfig
{
   void ExecuteContextArcMfe_Delft3d(object sender, EventArgs e)
   {{
      // Note this code will only work with plugins that implement the PluginsExtPublicCmd
      // COM object.
      COMObjectLateBinding cnet = new COMObjectLateBinding("ArcMfe_Delft3d.PluginsExtPublicCmd");
      cnet.Execute("executeCmd", new object[] {{ "een opdrachtje", "en de aansturing" });
   }
   ...
}

a simple wrapper class COMObjectLateBinding is used.
