    [This is the fifth in a series of posts on getting started with the new features in Entity Framework 4 based on the demos I did in my session at TechEd Europe in Berlin last week (Nov 2009).] Entity Framework v1 did not support a commonly implemented ORM feature called Lazy Loading . Entity Framework...
  • Blog Post: QandA: Is the ADO.NET Entity Data Model designer fixed in .NET 4?

    [I haven’t done QandAs for a long while – very remiss of me.] Anyway, I have been asked this one so many times lately that I felt a more public answer was needed. The short answer is: Mostly. Certainly it is good enough to get work done. The longer answer is below… History In the first version of Entity...
  • Blog Post: Getting Started with Entity Framework 4 – Complex Types and Entities

    [This is the fourth in a series of posts on getting started with the new features in Entity Framework 4 based on the demos I did in my session at TechEd Europe in Berlin last week (Nov 2009).] Complex Types make it easier to work with objects, allowing the grouping of related properties in Entities and...
  • Blog Post: SQL Azure and Entity Framework sessions from PDC 2009

    Two areas I am looking at right now are SQL Azure and Entity Framework 4. PDC had plenty of content on both these areas. Just need to find the time to watch some of it! I have added direct links to the standard definition WMV and the PPTs to download (which is what I am doing right now). SQL Azure SQL...
  • Blog Post: T4 Templates and the answer to life, the universe and everything

    [This is the third in a series of posts on getting started with the new features in Entity Framework 4 based on the demos I did in my session at TechEd Europe in Berlin last week (Nov 2009).] Entity Framework 4 relies significantly on the Text Template Transformation Toolkit (T4) to generate code from...

    [This is the second in a series of posts on getting started with the new features in Entity Framework 4 based on the demos I did in my session at TechEd Europe in Berlin last week (Nov 2009).] Code generation from the Entity Data Model (EDM) has changed significantly in version 4 of the Entity Framework...
  • Blog Post: Getting Started with Entity Framework 4 – Simple Model First Example

    This is the first in a series of posts on getting started with the new features in Entity Framework 4 based on the demos I did in my session at TechEd Europe in Berlin last week (Nov 2009). When adding an Entity Data Model to a project you are given the option to: Generate the Model from an existing...
  • Blog Post: Summary of the Entity Framework 4 changes introduced with Beta 2 and CTP 2

    I thought it would be useful (at least to me!) to summarise the new stuff in Entity Framework 4 given it actually comes in 2 parts . The list is a simplified and categorised version of this and this . General Foreign Keys now added: EF 4 now includes a new type of associations (Foreign Key Associations...
  • Blog Post: The relationship between Entity Framework 4 betas and ctps explained

    There seems to be enough confusion about the betas and ctps of Entity Framework 4 to warrant a brief post. Hopefully this should clear things up nicely. Put simply: Most of Entity Framework 4 (EF4) will ship with .NET Framework 4 and Visual Studio 2010 (.NET4/VS2010), however not all of it will . Most...
  • Blog Post: The Plan B is all my DEV305 Entity Framework 4 demos as slideware

    Next week I will be presenting Entity Framework 4 at TechEd Europe . At least that is what I hope to do. However my Lenovo T61P seems to have some other plans. A year back the screen packed in. The nice IBM man replaced it. All was well. Last week the screen packed in again. The nice IBM man replaced...
  • Blog Post: Entity Framework 4 Session DEV305 at TechEd Europe 2009 – what to expect

This presentation offers...
  • Blog Post: Midnight and the Azure and Entity Framework decks are now final and available for download

    You might have been following this series of posts on my preparation for Software Architect 2009. Well, this evening while sitting in a small hotel room in London (with no window and a dodgy tv) I completed both presentations and made them available for download on Slideshare. You can find them both...

    This is one of a series of posts on my preparations for sessions on Azure and ORMs at Software Architect 2009.

  • Blog Post: Countdown to Software Architect 2009 – Day three was Entity Framework 4 day. I love it!

    This is one of a series of posts on my preparations for sessions on Azure and ORMs at Software Architect 2009. The plan for day three: Nearly got it all done. However I ended up spending more time on EF4 than I had planned as … there is a lot of it! Gather up good posts and samples for EF 4 (will likely...
  • Blog Post: Entity Framework 4.0 Resources – documentation links, best blog posts and more

    This is one of a series of posts on my preparations for sessions on Azure and ORMs at Software Architect 2009. [Last updated 23rd Sept 2009] This is my attempt to pull together all (ok – most) of the improvements in Entity Framework 4.0 and aggregate useful resources against each. It is very much work...
  • Blog Post: Countdown to Software Architect 2009 – Day two and my love for Boot from VHD

    This is one of a series of posts on my preparations for sessions on Azure and ORMs at Software Architect 2009. The plan for day two: The Tuesday plan vs actual was … 100% spot on. Install Entity Framework CTP on Windows XP Mode. SUCCESS Install VS2010 into a Boot from HD Windows 7 VHD...
  • Blog Post: Countdown to Software Architect 2009 – Day one summary and the eureka moment

    This is the second in a series of posts on my preparations for sessions on Azure and ORMs at Software Architect 2009. In case you don’t want to skim through the whole post, the main things I learnt in day one are: 1. Never forget that install errors can be caused by something as simple as a corrupt file...
  • Blog Post: Entity Framework Interview – yep, this is what I look like!

    In March 2009 I presented on Entity Framework V1 and a little V2 at DevWeek 2009 . MikeT caught me on camera while I was there. I have (rather embarrassingly) only just got round to publishing the video. Ultimately I run out of excuses and was only left with … I’m shy :-) I presented an updated version...
  • Blog Post: Slides and links from NxtGenUG session on Entity Framework V1 and V2

    Had a great time on Tuesday (5th May 2009) at NxtGenUG in Oxford. A very friendly crowd, a fun user group and great to watch the banter between Alex and Barry first hand, rather than over twitter  :-) I also won a rubber duck – which justifies working in the evening in my book :-) Useful links:...

    I’m very pleased to see that DataDirect have a beta of their Connect for ADO.NET Entity Framework provider for Oracle which now adds support for he ADO.NET Entity Framework.

  • Blog Post: Entity Framework Books (with Amazon UK links)

    Having been asked 5 times today for recommendations, I figure this post is long overdue: There are several books out there but IMHO these are the two you should purchase. Julia is focused entirely on Entity Framework (all 800+ pages!) and Roger takes a broader look at ADO.NET3.5 but does a great job...
  • Blog Post: My “technology themes” for 2009

    I thought it would be useful to start 2009 by briefly summarising what you should expect to find on this blog over the coming months. Data : I will continue to spend time looking at what Microsoft and others are up to around working with data. You should expect to see plenty of posts on the ADO.NET Entity...
  • Blog Post: First published book on ADO.NET Entity Framework

    If you are following my blog or watched me present, you know I believe that Entity Framework will be a significant technology for .NET developers (even if EF v1 at times is incredibly annoying!). However we have been hampered by the lack of books available. I am waiting patiently for Julie to have her...
  • Blog Post: And the winner is… LINQ to Entities and the ADO.NET Entity Framework

    In 2001 we first demonstrated Object Relational Mapping (ORM) technology for .NET – ObjectSpaces . However it has taken 6+ years to get to the point where we have released an ORM. Actually we released two. The release of Visual Studio 2008 in November 2007 gave us our first shipping ORM – LINQ to SQL...
