    I am using Entity Frameworks Beta 3.  In the AdventureWorks database the generated ssdl may have an error in the EntitySet tag.  It is missing a Schema tag for Production tables.  Interesting that the Container name is "Production".   Is this something that will change in the released version?   Likewise in the Northwind database no schema tags exist in the EntitySet tags and the Container name is "dbo". email: RichHarrigan@hotmail.com.

    It seems that Entity framework is designed with object stateful in mind, how does it works with web application,which objects are a stateless mode.

    @Saman, The Entity Framework is part of the .NET Framework 3.5 SP1 install.  The Pre-Release version is an old version that was available before 3.5 SP1 was released.  Look at http://www.microsoft.com/downloads/details.aspx?FamilyId=AB99342F-5D1A-413D-8319-81DA479AB0D7&displaylang=en for the download of 3.5 SP1. Thanks, Carl
