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".

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 Ahmadi said on June 16, 2009 9:13 AM:

I have been trying to install the framework but getting ADO.NET Entity Framework 1.0 (Pre-Release Version) -- ADO.NET Entity Framework 1.0 (Pre-Release Version) can only be installed if Microsoft .NET Framework 3.5 is installed. ERROR.

I have spent like 6 hours to fix it but now success.

Please any idea what should i DO?

# carlyates said on June 16, 2009 11:12 AM:

@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
