CONDG Entity Framework Presentation Follow-ups

Thanks to everyone who came out last night (73...a great showing considering the start of Memorial Day weekend and the Indiana Jones IV opening) to CONDG for my Entity Framework presentation . We had some great questions I didn't know the answers to which I'll investigate and respond to soon. Is there a caching mechanism for ObjectContext? Thinking of this in a web (ASP.NET), disconnected between request/response environment. Is the conceptual, mapping, and schema XML loaded up all at once or is the XML representing entities loaded up individually upon instantiation / use? The EF wizard interrogates the physical data store and produces the 1:1, Type per Table initial EDM. Is it possible to model the EDM first leveraging it to generate the physical schema? Referring to this performance comparison between the traditional Sql Client, Entity SQL, and LINQ to Entities, what's the break-down of time consumed? The ADO.NET team posted a follow-up with the break-down here . Grant

Installing VS2008 / .NET Framework 3.5 SP1 BETA1

I've been awaiting an improved Entity Framework EDM designer tool since the CTP released in December. Well, with an Entity Framework presentation looming (May 22nd), the Redmond gods responded: VS2008 and .NET Framework SP1 BETA1 . I uninstalled all sorts of CTPs and now am the proud owner of a laptop with VS2008 and .NET 3.5 SP1 BETA1. Below find the steps I followed. Please heed the warnings and directions within the readme ( .NET 3.5 Framework SP1 BETA1 , VS2008 SP1 BETA1 ) explicitly. Also, this is BETA software...expect minor issues and don't install on production equipment.

VS 2008 / .NET 3.5 SP1 BETA Released

Update (5/12/2008) : And...we're back! Visual Studio 2008 and .NET Framework 3.5 Service Pack 1 Beta Scott Gu Somasegar Remarkably, they delivered M:M conceptual modeling in the Entity Framework designer. Thank you! (Stayed up 'til 3AM a while back trying to get it working...yeah, it wasn't supported then. Super.) ---------------------------------------------------------------------------------- Update (5/10/2008) : Looks like the Elegant Code post was pulled. Sigh. We'll have to wait for the official announcement. ---------------------------------------------------------------------------------- It doesn't appear to be all that pronounced just yet but Service Pack 1 for both Visual Studio 2008 and .NET 3.5 is out! This should give much relief to the eight steps and MSIs now required. (Hey, it's beta/CTP, right?) Credit to Elegant Code for providing the links.
