I am using ArcGIS 10 and MS Visual Basic 2008 Express Edition to migrate our existing VBA customization to ArcMap Add-Ins.

The existing VBA used IExportOperation that is in ESRI.ArcGIS.DatabaseUI and need to be defined in the VB.NET. But  I can't find reference of ESRI.ArcGIS.DatabaseUI in the VB.NET? Anyone know how to solve it?
