Remarks

The MassUpdateDataType<T> method is useful when you rename a particular business class and wish to update references to this class in your existing reports. As this method is static, you can call it from any appropriate context where the IObjectSpace instance is available. For example, you can call this method from the overridden ModuleUpdater.UpdateDatabaseAfterUpdateSchema method in the Updater.cs (Updater.vb) file. The generic T parameter specifies the report data type (business class type implementing IReportDataV2), used in your application.
