Wrapping up SDP Nov. 2012

Thursday, November 29, 2012

Wow, a conference that lasts 8 days, that a first. So here’s the gist of what I taught in 5 of these days: What’s new in WCF 4.5 In this 1-hour session I covered some of the important new features of WCF 4.5, such as Intellisense for configuration, UDP and WebSockets bindings, and improved support for streaming and compression. Debugging the Web with Fiddler In this 1-day tutorial we saw how to use Fiddler to debug, test, and...

BUILD 2012 – Day 1 Overview

Thursday, November 1, 2012

Ok, first, just in case you aren’t familiar with my work – I’m a server/web/cloud guy, not a client guy, so all the hype about Windows 8 and Phone 8 sounds to me like “bla bla bla”. I’m into servers and Windows Azure, so day 2 and on is more to my like than Day 1. So day 1 began with the keynote where Steve Ballmer did his “shopping channel” appearance, showing the various hardware running Windows 8. BTW, in the first photo, on the left, you can notice an 82” surface ....

Entity Framework 4.1– beware of the DbSet.Find method

Monday, August 1, 2011

One of the new features of Entity Framework 4.1 is the DbContext API which is basically a simplification of the ObjectContext API, and is intended to make your life a bit easier. In this new API you can find the DbSet.Find method which according to MSDN does the following: “Uses the primary key value to attempt to find an entity tracked by the context. If the entity is not in the context then a query will be executed and evaluated against the data in the data source, and null is returned if the entity is not found...

SDP lectures slides

Thursday, March 24, 2011

  Last week we had our annual SDP conference in Sela’s offices and in Crowne Plaza in Tel-Aviv. I had the pleasure of talking about several of the technologies I’m dealing on a daily basis (well, almost every day) which were: Entity Framework. The first day of the convention was all about Entity Framework. Erez, Gil, and myself gave several lectures dedicated to Entity Framework. The day ended with an “EF expert panel” which I enjoyed very much. I think will make a habit or doing this panel every year. ...

Combining Entity Framework Self-Tracking, Extensible Metadata, and Data Annotations

Sunday, October 3, 2010

A few months ago, I read this great post about the Portable Extensible Metadata (PEM) of Entity Framework 4. The PEM relies on the extensibility of the entity framework EDM, which enables you to add your own XML content into the EDM. Once placed in the EDM, you can write code that investigates the MetadataWorkspace and do operations according to what you’ve written in the EDM. One usage for example which is demonstrated in the PEM extension is adding validations to entities and properties, and placing this validation information inside the EDM for later use. To let the...

Your vote is important

Sunday, September 12, 2010

The Entity Framework team has opened a wish list website to get input about what bugs people in Entity Framework 4. If you’ve ever used EF and complained about it (which happens to me on a daily basis), this is the time to speak out. Read more on the original blog post

Debugging Distributed Transactions: MSDTC network problems

Monday, July 19, 2010

It has been a while since I’ve published a post in my blog. In the past couple of months I’ve been working hard on writing the new official WCF 4 course for Microsoft and writing a book about ASP.NET 4 together with Shay Fridman, but things are calming down and I’m getting back to business. A few days ago Sasha started writing several posts about debugging distributed transactions. One issue that developers need to be aware of is the need to configure the transaction coordinators in all the machines that are involved in the transaction....

PDC 09 – Entity Framework 4

Wednesday, November 18, 2009

First time that I can say – there are MANY people that use EF4. How do I know? because the session had the room filled with people, with people waiting outside ! EF 4 is great. It solved many of the problems of EF3.5 and made the technology more mature and useful. What annoyed me in the lecture is that it showed all the features of EF4 that people already know of (well, I know of). The title was misleading because I thought they will talk about new features that don't exist currently. Here is the list of features, and links...
