I've spent 16 straight hours trying to figure this out, so any help would be greatly appreciated... I'm doing everything the same for each type of app., and in any console version I can access my ModelEntities (System.Data.Objects.ObjectContext) object's members, but can't in any ASP.NET app, for example: OrderEntities o = new OrderEntities(); at which point 'o' isn't recognized by ...

I am doing the preliminary foray into Entity Framework in preparation for creating a custom license tracking tool with a thirdparty database. The database uses composite keys (is that the right term? Two keys used in conjunction to produce a unique record ID). I am having some difficulty in getting the Model to play nice with me. I have use EF a bit before with simpler homemade databases, ...

This post is done using Visual Studio 2010 Beta 2 Not sure if I did this correct but this is how I did it; Maybe it can be of some use to some one else.

One Problem; Required Fields (not null) from ...

Hi, we'd like to develop .Net applications using Entity Framework Data Access Layer for Informix, that is (supposed) supported on IBM Data Server Provider for .Net. We have tried 9.5 and 9.7 versions, with no success. It's impossible to find a clear statement from IBM about EF support on Informix, supported configurations, etc. Any experiences of EF on informix? Regards,...

Hi all, I'm dealing with a major issue that I cannot figure a work around without major issues. Here's the basic scenario: You've got an order that the person is working on, it has it's base information and then it can have one or more detail line items where the product is selected etc. Dealing with a single item is easy, you can either store it in the Viewstate (serialize it) or the ...

Greetings, I didn't see anything related to this in the forums (if I missed it, I apologize), so I figured I'd ask. I'm playing with the Entity Framework CTP 2 bits; more specifically I'm playing with the new POCO support which this release supports. Cool stuff. So far I've been able to successfully create a database / add objects, etc. using the bits: using ( var conn...

I'd like to use the EF from within a managed stored procedure. From what I remember, System.Linq.dll can't be loaded into SQL Server 2005--has anything changed for 2008? (Which I'm using.) If so, which version of the EF is supported? -- 1 or 4?

I think most of you may work with the latest version of SQL Server and deploy it to the target machine which have a relative old version on it. Like using SQL Server 2008 on production machine and SQL Server 2005 on target server. While working in such situation with Entity Framework, It made me a little bit frustrated. I designed the database schema using SQL Server 2008, have table field ...

Hello, Entity Framework est ouvert à travers des providers, donc c'est plutôt lui qui pourra discuter avec Oracle. Il existe par exemple un provider mySQL pour Entity Framework : http://www.devart.com/dotconnect/mysql/ Pour WCF RIA Services, tu peux le découvrir à travers une série de tutoriaux sur mon blog: http://blogs.msdn.com/davrous/archiv...vices-1-4.a spx J'en parle ...

I am having a similar issue, however, mine is disconnected and via a wcf call. Just wondering if you have made any progress? Part of my problem is that most examples I have seen seem to be without complex relationships.

It is possible in SQL Server 2008 with EFv1 (the .NET 4 CLR is completely new and SQL Server 2008 will not host it). You will need to add System.Data.Entity.dll and its dependencies with the UNSAFE permission set in order for it to work.
