I am using Entity Framework 4.0 in an ASP.NET 4.0 Web Form.
All is fine on the development server. But when I get to the production server, I my Elmah logs this erro
I dont see any workaround till date. So if you are using SQL Server 2008 Express, please right click on your edmx, open it with XML (Text) Editor and set ProviderManifestToken="2005".
ProviderManifestToken="2005"
Doesn't sound that good. But its all I have got as of now.
