I finally decided not to wait till I finish the whole recording which it seems is going to take some good time. And so I started to split this recording session/screencast into multiple parts and post them.

About Part 1

First part is about 10 min in length. And is an introduction to Entity Framework 4.0 with brief about its short history. This part also include a demo about new vs2010 designer enhancements for EF4. Also the screencast shows how to do a refactor to complex type using EDM designer.

Last week I introduced a new screencast on another OData Developer tool. It was about how to use LinqPad to query OData service with C#, LINQ & WCF Data Services Client APIs.

The screencast shows how to use LinqPad to connect to and query OData Services using LINQ and WCF Data Services Client APIs. Showing how LinqPad can be useful as a developer tool to test queries against any OData Service.

I case you missed it, you can watch it on ODataPrimer website. You can also download an HD video (~48Mbs). The package contains 2 videos. One of them is the one hosted and it’s a 10 min video. And the other is ~14 min. I had to trim it to fit into youtube. The 14 min video contains additional stuff in case you are interested.

You can also subscribe to ODataPrimer channel on yourtube for future updates and videos.

Hope you’ll enjoy it.

Last week I introduced a screencast talking about OData Visualizer Extension for VS2010 on http://odataprimer.com community.

It’s a How-To video on how to download, install and start working with OData Visualizer Extension for Visual Studio.Net 2010. OData Visualizer is an extension for VS2010 made by Microsoft Data Modeling team

I case you missed it, you can watch it on ODataPrimer website. You can also download an HD video (~35Mbs).

Last month, Friday 23rd April, I had a chance to present at Code Camp Reloaded event hold at Faculty of Engineering Ain Shams University in Cairo.

My presentation was about Exploring Design Patterns. I gave a general introduction about what’s design patterns and why they exist.

In this session I talked about different Design Patterns categories and explored 2 interesting design patterns:

• Decorator as example of structural patterns
• Strategy as example of behavioral patterns.

I also demonstrated the 2 patterns and showed examples from within .Net framework itself where these 2 patters are applied and used.

I uploaded code samples and presentation to my skydrive

Few months ago, on September 2009 my friend Rashid started to blog about this open source project “Shrinkr”. And I got a chance to assist him on this.

In the last few weeks we were working on preparing this first stable release. And now we got it and it’s live on http://rdir.in.

Yesterday Rashid announced the first release which you can download from here.

In this post I’m going to show few screenshots of the live Shrinkr. And highlights few technologies used on it.

Introduction

You might hear of KiGG, the open source project that is currently live as http://dotnetshoutout.com. I wanted to expose part of KiGG data as an OData Service for read only. But I figured out that exposing raw KiGG schema might not be useful. So I had to choose between 2 options that were up to my mind:

• Build some views on the physical store -database-. Create a new entity data model for those views and use the new data model context for DataServiceContext.
• Use Entity Framework 4.0 conceptual model function feature with complex types to simulate views. It’s like building views on the conceptual model itself and not the store model.

I picked the 2nd option. The sample downloadable sample is available at the end of this post.

You might noticed that I just passed the “UPGRADE: Transition your MCPD Enterprise Application Developer Skills to MCPD Part 1” exam last week. And I thought to take the 2nd part of the upgrade exam one on the same week.

Exam 70-569 “UPGRADE: Transition your MCPD Enterprise Application Developer Skills to MCPD Part 2”

Again thank God I passed the second part which is exam 70-569 last Wednesday 31st March 2010. You are eligible to take this exam if you are “MCPD Enterprise Application Development” for .Net 2.0. Achieving this exam gives the following Credential:

• MCTS .NET Framework 3.5, Windows Communication Foundation Applications.
• MCPD: Enterprise Application Developer 3.5

To gain the MCPD Enterprise Application Developer 3.5 certification you’ll need to complete part 1 too.

It worth to mention that this exam covers for the following exams:

• Exam 70-503 TS: Microsoft .NET Framework 3.5 - Windows Communication Foundation.
• Exam 70-565 PRO: Designing and Developing Enterprise Applications Using the Microsoft .NET Framework 3.5.

The exam was more than 45 question. I got score 925 for WCF and 1000 for Designing and Developing Enterprise Applications.

In general, both exams were easy ones, maybe because I’ve been working for couple of years now using .Net 3.5 beside 8+ on .Net framework on general. I started this certificate things since the release of .Net, and it was a good experience that I’m gaining benefit of now. Good luck to everyone.

IMPORTANT
IF YOU ARE HERE LOOKING FOR BRAIN DUMBS OR TEST KING COPY OF THIS EXAM THEN THIS IS THE WRONG PLACE.

I’ve been preparing for upgrading my MCPD certification from .Net 2.0 to .Net 3.5! And the upgrade exams released March 2009. And so I took my action these days and started to schedule and take the 2 upgrade exams.

It worth to mention that if you are an MCPD Enterprise Application Development, then it’s better for your to do the upgrade exams. This is much cheaper. The 2 upgrade exams equals to 6 one by one exams. You’re not only going to save your money, but also will save your time. Unless of course you already gained the credentials if you passed the beta exams.

At the end of last month (27-28 Feb 2010) I got the opportunity to participate in Cairo CodeCamp event by giving a session about “Getting Started with Entity Framework 4.0”.

Here is summary of my session –taken from Cairo CodeCamp web site-:

An introduction to Entity Framework 4.0 that will be shipped as part of .Net 4.0 and VS.Net 2010. Exploring new and enhanced features of Entity Framework 4.0. Walking through building entity data model using VS.Net 2010 and Entity Framework 4.0. Examining new design features in Entity Framework introducing Persistence Ignorance.

I uploaded my session and demos. You can download them now. I hope you’ll enjoy the demos and presentation. Click here to download.

All sessions should be posted soon to Cairo CodeCamp web site. Keep tracked for updates.

I have a plan to record my session as screen cast in English and post it here as well. But can’t promise when this will be as I have many other things I committed to recently.

Keep tuned anyway you might find interesting stuff posted soon.

Before I blog about my presentation and the great experience I had during Cairo CodeCamp days, I want to point to one cool Podcast show about “Women in Technology in the Muslim World” made by Scott Hanselman with Abeer and Lamees 2 Egyptian ladies who work for DashSoft

Abeer is senior system analyst who has over 6 years of experience on this field. Lamees is a software engineer and programmer who is transferring to system analyst role, and she is doing good job about that.

here is the description of this podecast taken from hanselminutes.com:

“Scott's in Egypt today and he had the opportunity to sit down with Lamees and Abeer, two successful women in IT. Lamees is a programmer transitioning to Systems Analysis, and Abeer is a veteran Senior Systems Analyst and Agile Project Manager at Dashsoft. Nearly 50% of the people at Cairo Code Camp are women. What is Egypt doing right to encourage so many women to choose technology as their career?”
