TRAINING: “Hardcore Entity Framework” in London with Julie Lerman, 22nd October
Entity Framework 4.0 (EF4) it the strategic .NET ORM from Microsoft. Hmm…. the “strategic” word. I will come back to that. However the important bit of news is we have Julie Lerman at Microsoft in London on the 22nd October devoting a full day to training on “Hard Core Entity Framework 4”. It’s a rare visit so if you’re interested in learning about the data stack from a recognised world-wide authority and author on the topic then register now (£300). Now back to that word “strategic”. As developers ......

Links from UK TechDays 2010 sessions on Entity Framework, Parallel Programming and Azure
[I will do some longer posts around my sessions when I get back from holiday next week] Big thanks to all those who attended my 3 sessions at TechDays this week (April 13th and 14th, 2010). I really enjoyed both days and watched some great session – my personal fave being the Silverlight/Expression session by my friend and colleague Mike Taulty. The following links should help get you up and running on each of the technologies. Entity Framework 4 Entity Framework 4 Resources http://bit.ly/ef4resources ......

Getting Started with Entity Framework 4 – Lazy Loading
[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 4 adds that feature. In Beta 1 it was known (confusingly IMHO) as Deferred Loading. In Beta 2 it is (thankfully IMHO) known as Lazy Loading. You run up against the absence of Lazy Loading in v1 when you ......

Recent resources on Entity Framework 4
[UPDATED 23/3/2010 with two new links from developmentor on STEs] I just posted on the bits you need to install to explore all the features of Entity Framework 4 with the Visual Studio 2010 RC. I’ve also had a quick look (March 12th 2010) to see what new resources are out there on EF4. They appear a little thin on the ground – but there are some gems. The following all caught my attention: Julie Lerman has published 2 How-to-videos on EF4 on pluralsight.com. You need to create a free guest pass to ......

Installing all the bits to demo Entity Framework 4 on the Visual Studio 2010 Release Candidate
Next week (17th March 2010) I am presenting on EF4 at www.devweek.com in London (and Azure on the 18th). Today I wanted to get all the latest bits on my demo machine and also check if there are any cool new resources I can point people at. Whilst most of the new improvements in Entity Framework come with the Visual Studio 2010 RC (and the RTM), there are a couple of separate items you need to install if you want to explore all the features. To demo EF4 you need: Visual Studio 2010 RC Download and ......

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 the reuse of these groupings across Entities. The first release of Entity Framework included Complex Type support but did not expose this capability through the Entity Data Model Designer. The good ......

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 the EDM. I thought it would be useful to show a really simple example of T4 in action which is nothing to do with Entity Framework. In a Visual Studio 2008/2010 solution, add a new item of type Text ......

Tangible T4 Editor – a life saver
I have been working with T4 (Text Template Transformation Toolkit) lately thanks to the Entity Framework team moving their code generation model over to T4 in Visual Studio 2010. However by default Visual Studio 2008 and 2010 do not include syntax highlighting or intellisense support for T4 files, which makes it rather difficult to work with them (very difficult at times!). Thankfully there are partners who address this. The one I am using with Beta 2 of Visual Studio 2010 is the Tangible T4 editor. ......
