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

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.
