Microsoft .NET framework 3.5 Service Pack 1 and Visual Studio 2008 Service Pack 1 now have public BETAs. The service pack of Visual Studio 2008 has really interesting stuff. Highlights I'm interested in are performance improvements in HTML editor, collection of JavaScript intellisense hotfixes plus new ones enabling better JavaScript intellisense for libraries like jQuery, JavaScript Code Formatting, ASP.NET Routing engine (the one used in ASP.NET MVC, it is actually developed as separate component), ...
The most recent versions of the ADO.NET Entity Framework Beta and ADO.NET Data Services Beta are now available!

These will also be the final Beta prior to the RTM of these two projects. For more information on these releases and on changes that have been since the last public releases, check out the ADO.NET Team and ...
Microsoft has released a training kit for .NET Framework 3.5 Enhancements. It includes labs, demos, and Power Point files for the following technologies: ASP.NET MVC ASP.NET Dynamic Data ASP.NET AJAX History ASP.NET Silverlight controls ADO.NET Data Services ADO.NET Entity Framework ...
Last weekend I blogged about creating ADO.NET Data Service with the help of of Entity Framework Tools CTP. I do hope you had a good luck installing this tool but I just realized that I forgot to share with you my experience of the installation. The first time I tried to install it on my machine, I got the warning dialog saying the installation requires a patch for Visual Studio 2008. You need to stop the installation of Entity Framework tools and apply this patch first. It can be downloaded patch ...
This is the email I sent to SilverKey Tech. Egypt dev team yesterday, sharing here as usual. Article: Info Q: Don't Let Consumers and Service Providers Communicate Directly Just because someone is developing with Web Services does not mean they are following SOA principles Just because you're using HTTP and HTML doesn't mean you get into that camp and vice versa Weblog: "Making IT work" - Musings of a Holistict Architect Weblog: Udi Dahan Article: Autonomous Services and Enterprise Entity Aggregation ...
In my previous post, I gave you the introduction of ADO.NET Data Service. Now I will show you step by step how to create an ADO.NET data service using Visual Studio 2008 and the Entity Framework Tools (December 2007 CTP). I am going to use the Northwind sample database to implement the service in this example. The Northwind database can be downloaded from: http://go.microsoft.com/fwl... 1. Create an ASP.NET Web application (C#) in Visual Studio. Let's name the project NorthwindDataService ...
The ADO.NET Data Services framework lets you create and access flexible data services that are integrated with the Web. The services use URIs to locate and identify data, and use simple, well-known formats to represent the data, such as JSON and XML. Data is made available across the Web in the style of a representational state transfer (REST) resource collection that is addressable by using URIs. ADO.NET Data Services expose relational data by using the Entity Data Model as specified by the ADO.NET ...
I have always wanted to blog on the Entity Framework, not only because I am an early adopter of new technologies, but also because I actually created an entity framework myself on my previous job and I believe my whole mind-set was pretty close to Microsoft's design of the Entity Framework although I have to admit my stuff was nowhere near MS in terms of scalability and extensibility. I have been playing with Entity Framework since its debut (at that time its codename was "Astoria") in MIX 07 and ...
I am a huge fan of Pablo Castro(the presenter). Astoria has become ADO.NET Data Services Framework. Data in the web: Ajax applications Silverlight applications Online Services Mashups Restful Interface for Data: Just Http Data as resources, HTTP methods to act on it. Uniform URL syntax Every piece of info is addressable Multiple representation Use regular HTTP content-type negotiation Atom, JSON, Plain XML Book: Restful Web Services Drill down data using Astoria(http request or get) Model and Operation ...
How great was the LA Launch kickoff event on Wednesday? It seemed to be a good time for those that got in. The sold out event began with Steve Ballmer's keynote at the Nokia Theater and continued through the day at the Los Angeles Convention Center. Most exciting for myself and the ADO.NET team, my Getting Started with the Entity Framework chalk talk saw more than a full room as people crowded the entrance to listen in. For more information on the launch or a chance to check out the Virtual Launch, ...
As much as I have enjoyed playing with the Entity Framework (Beta 3), I will be uninstalling shortly after this post. The fact of the matter is, my company is not prepared to go to production in a couple of months with something that hasn't seen a lot of action. The EF certainly seems stable enough, but, I can respect this decision. The good news is that we are still using VS 2008 & .Net 3.5. Also, my plan is to maintain a design that we can migrate to the EF without too much effort. Hopefully ...
26 developers from 'West-Vlaanderen' interested in LINQ and the Entity Framework attended (and liked) my IT Club session yesterday. This session will be repeated for Ordina and some local .NET usergroups. I this session i give an introduction to LINQ and the needed C# languages enhancements, focus on OR-mapping and contains demos on Linq to SQL and the Entity Framework. Interested in attending, please mail me or reply to this post. Or you can download the slides here ...

New developers often ask me about C# delegate, as they got a bit confused about the basic concept and specially maximum of the reference contains and discussed from an advanced view. Well I think delegate is really simple, when you grab it's basic idea. So what is delegate? Basically it is similar like the old "C" age function pointer, where functions can be assigned like a variable and called in the run time based on dynamic conditions. C# delegate is the smarter version of function pointer which ...
I did some research in the OR mapping capabilities of the ADO.NET Entity Framework with Beta 3. Goal was to see how inheritance works. Here a quick walktrough. Database Started with 2 tables (wich have a 1-1 relationship). Table Employees which holds Name and JobTitle.Table SecurityInfo which holds Username (let's assume that this field is a network login) Entity ModelCreated the EntityTypes in the Entity Data Model as followed. NetworkUsers is inherited from Employee. Here Employees is mapped to ...

Two months ago, after listening to .NET Rocks! show with Daniel Simmons, I was really curious to learn more about ADO.NET Entity Framework (EF). As part of my learning I was ready to write a tutorial on how to get started with this framework. However there were no tools available at the time and with instructions on how to manually edit XML files the article turned very long, and quite frankly looked very boring. Hence I decided to postpone publishing it and wait for the tools to came out. This week ...
Yesterday we started accepting FREE registration for the 2nd Demo Day. If you remember from the 1st one, Demo Day is an event we love to hold being our way to expose knowledge and most importantly excitement regarding the latest pre-release technologies to the developer community in Egypt, mainly focusing on technologies bound to Microsoft, as our chosen method of getting things done, plus other technical inspirations that we'd think most developers would benefit from, at least as a new way of thinking. ...
I blogged previously about the ADO.NET Entity Framework Overview whitepaper. Now you can download a CTP to play with. Note that these features will NOT be in ADO.NET 3.0. This is in some future version. This is a very early CTP and is extremely limited. The “ADO.NET vNext Entity Data Model Designer Prototype CTP” enables developers to design their data access stack using a designer in Visual Studio.This is an unsupported tool that showcases upcoming ideas for ADO.NET vNext tooling and Visual Studio ...
I’ve mostly stayed away from blogging about DLinq and other .NET 3.0 goodies, because I think they’re too far out in the future to be worth that much attention. However, I do think that Linq is worth keeping an eye on because I think it’s going to be one of the best parts of (insert .NET language here) 3.0. And to go along with DLinq, there are some massive changes coming to ADO.NET. I’ll follow up on these more when I feel the time is right, but for now, it’s worth ...
Microsoft has released today the first CTP of the ADO.NET vNext with a preview build of the ADO.NET Entity Framework including samples and white papers.
