Assemblies: Microsoft.Office.Tools.Excel (in Microsoft.Office.Tools.Excel.dll)
Microsoft.Office.Tools.Excel.v4.0.Utilities (in Microsoft.Office.Tools.Excel.v4.0.Utilities.dll)
In a document-level customization, the application domain for the assembly unloads when the workbook host item shuts down.
In an application-level add-in, the application domain does not unload when the workbook host item shuts down. Also, the underlying workbook object is no more available. To access the workbook before it shuts down use BeforeClose instead.
