[Publication] New ".Net Framework 4.5 Parallel Extensions Cookbook" Book is now available in English

I am happy to announce, that the English book “.Net Framework 4.5 Parallel Extensions Cookbook”, which I have technically reviewed, is now available in the Packt Publishing online store. You may buy it as eBook and paper book.

If you are interested in .NET 4.5 and Parallel Programming, this book is for you since it contains everything necessary for you to master this technology quickly. Examples and explications provide thorough information on all new features. I personally have reviewed all of the examples and I hope they will give you all insights you expect.

Here is the table of contents (look under the “Table of Contents” tab):

[Event] TechED 2009 – Experience Summary

Last Sunday I arrived at the TechEd 2009 in Berlin and registered in the evening. There were many people from all over Europe and even Speakers from the US. About 736 Sessions for over 7000 people were announced. What an event, the week promised to be awesome!

I did 4-5 session per day and also tried to do as much Hands-On-Labs and Interactive Discussions as possible. When I got a possibility to talk to Microsoft collaborators on upcoming technologies I did it!

I attended at sessions on Architecture, WCF 4.0, WIF, Dublin, Parallel Programming, SQL Azure and Visual Studio 2010 and many others. An enormous amount of news was given to the audience and I was very excited of what was presented.

WCF 4.0 will not have major updates but will get default bindings, default behaviors and standard endpoints that will make configuration in most cases much easier. There will be new protocol mappings, a whole new routing mechanism (!!!) and new ad-hoc service discovery features that make it possible to detect services on the network automatically. It will be possible to configure the content-type of the service return format (xml, text, json, atom, etc...).

The Geneva project, that will rewrite history for security handling in application, was renamed to WIF (Windows Identity Foundation). This new claims based approach decouples security handling and management from application development. It works via Tickets that are delivered via an STS (Security Token Service). Cardspace 2.0 will be used to provide users with the possibility to select an identity.

WIF is the framework that is used inside applications for being able to use Tickets and recover claims that are important for them. Finally an abstraction layer for security, something that will make application development much easier and security handling much more flexible!

Dublin, which was renamed to "AppFabric", will provide a new hosting environment for WCF. Some extensions to IIS were shown, that add for example, a new management Dashboard that greatly aids in managing WF 4.0 Workflows and WCF services. WCF 4.0 in conjunction with Dublin will really provide a whole new experience and will be a good alternative for BizTalk in many use cases. Definitely worth looking into it when it will be shipped!

The new Parallel Programming features in .NET 4.0 will make it much easier to get the most out of multi-core machines. In most cases you just have to identify the parts of the application that may be parallelized and use Tasks, PLINQ and the TPL (Task Parallel Library) to optimize for parallel processing. Thread optimization and complicated algorithms will rarely be necessary. There are many new features in Visual Studio 2010 that further aid the developer to master parallel development (Thread/Tasks can be separately debugged and profiled, Performance analysis can be done, etc...).

SQL Azure will be a relational database in the Cloud that can be used together with Windows Azure or client applications on client servers. The experience is seamless and you really see no difference inside your applications. You even can use SQL Server Management Studio (in a new version that can be found here) to manage your online databases. Your databases can have a size be up to 10 GB and the same on-a-use based payment model is applied as with Windows Azure ($9.99 and $19.99 payment plans).

And I could go on and on. This was really an amazing event and I am very happy that Winwise sent me to it. I would love to get into more detail on all the new features, so just contact me if you want additional information.

[Parallel Programming] TechED 2009 – Parallel Programming in .NET 4.0

There are many new features in .NET 4.0 concerning Parallel Programming such as Tasks, PLINQ, Coordination Structures and many more. Most of these were also presented during the session at the TechED.

• Tasks make it much easier to cope with parallel processing optimizations since they add an abstraction layer. Complicated thread programming is not necessary anymore.

• Parallel LINQ (PLINQ) is a very easy way to add parallelism to your applications since you just have to add knobs to the LINQ expression and the processing is automatically parallelized.

• Task Parallel Library (TPL) provides APIs, structures and objects for parallel programming

• Coordination Structures can then be use inside and outside the code that is parallelized to assure that the processing is correctly done.

• Visual Studio 2010 will include parallel debugging and tracing and many other feature for parallel programming. Here an example of a parallel stack diagram.
