Assembly: Microsoft.Office.Tools.Common (in Microsoft.Office.Tools.Common.dll)
If your add-in no longer requires a custom task pane, you can use the method to clean up resources used by the task pane while the add-in is still running. When you use this method, the Dispose method of the specified CustomTaskPane object is automatically called.
The Visual Studio Tools for Office runtime automatically cleans up resources used by the custom task pane when the add-in is unloaded. Do not call the method in the ThisAddIn_Shutdown event handler in your project. This method will throw an ObjectDisposedException, because the Visual Studio Tools for Office runtime cleans up resources used by the CustomTaskPane object before ThisAddIn_Shutdown is called.
