When I use ADO.NET DBContext Generator with Entity Framework 4.1 installed on an EDMX

  • 0

When I use ADO.NET DBContext Generator with Entity Framework 4.1 installed on an EDMX I got the following error:

Error: this template attempted to load component assembly
‘Microsoft.Data.Entity.Design, Version=10.0.0.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a’. For more information on this problem
and how to enable this template, please see documentation on
Customizing Project Templates.

I’m using VS2010 with SP1, Entity Framework 4.1 from NuGet, .net 4 Class Library

Am I missing something?

I have “Microsoft Entity Framework June 2011 CTP” installed and when I select it from the project target frameworks then the template “DBContext Generator” works. IS that mean I have to uninstall the CTP to get it working with normal .net framework 4.0?

    I has to re-install Entity framework to get it work using:

    ADONETEntityFrameworkTools_enu.msi USING_EXUIH=1 /log "dd_ADONETEntityFrameworkTools_enu_MSI.txt"
