    Unable to find the requested .Net Framework Data Provider.

    877720
      When I use entity framework in a windows form application, it throws an error:

      Unable to find the requested .Net Framework Data Provider. It may not be installed.




      but I've already installed ODTwithODAC112030 sucessfully and the Oracle.DataAccess.Dll is present in

      D:\app\admin\product\11.2.0\client_1\odp.net\bin\4


      in machine.config, I can see the provider like below:

      <system.data>
                <DbProviderFactories>
                     <add name="Oracle Data Provider for .NET" invariant="Oracle.DataAccess.Client" description="Oracle Data Provider for .NET" type="Oracle.DataAccess.Client.OracleClientFactory, Oracle.DataAccess, Version=4.112.3.0, Culture=neutral, PublicKeyToken=89b483f429c47342"/>
                     </DbProviderFactories>
           </system.data>



      So what else do I need to check?
