just updated to 10.1 and I'm having issues moving from 10.1. I get the errors with my ADF reference when trying to create custom tool bars


'BaseToolbar' is ambiguous in the namespace 'ESRI.ArcGIS.ADF.BaseClasses'.  

Any suggestions on how to convert? I have the following references imported:

Imports Microsoft.VisualBasic
Imports System
Imports Microsoft.Office.Interop
Imports ESRI.ArcGIS.Geodatabase
Imports ESRI.ArcGIS.esriSystem
Imports System.Windows.Forms
Imports ESRI.ArcGIS.Carto
Imports ESRI.ArcGIS.ADF.Connection.Local
  • What Visual Studio version/type are you using? What .NET Framework are you targeting?
