In order to keep things in perspective, Uri has prepared a series of interesting demos that illustrate the techniques used to improve the development and management experience...( read more ) Read More...

As the WCF team already announced, the first chapter of the WCF Extensibility Guidance is now available on MSDN . This paper is the result of an effort I started a few months ago with my colleague and friend Pablo Cibraro . Our goal was to provide a detailed guidance of the major extensibility points of the WCF runtime. In that sense, we decided to cover major areas of the WCF extensibility programming model such as channels, client-dispatcher, security, hosting, metadata, RESTful service and even...( read more ) Read More...

In a previous post we explained the programming model of Microsoft's StreamInsight adapter framework. The fundamental capability of this framework is to streamline the flow of events in and out of the StreamInsight hosting application. One of the main advantages of this model is that enables developers to create their own adapters that can be leveraged on StreamInsight-based solutions. On this post we will explore the details of implementing an RSS/Atom adapter using StreamInsight's adapter framework...( read more ) Read More...

Approximately hardly there is more than year back we have seen a new services platform - ADO.NET Data Services. Its occurrence has marked the beginning of wide use of the REST-approach by many developers. At that time this platform was represented as the convenient tool for access to data through HTTP. Lately it is possible to understand, that this tool is really successful - huge number of developers have started to use immediately it in the projects. The reason for it is quite logical - use of...( read more ) Read More...

Astoria team has released next CTP of ADO.NET Data Services 1.5. In comparison with previous release, CTP2 is really big work and we can observe now already that ADO.NET Data Services becomes even more powerful platform. As a whole it is visible, that development of Astoria is directed on more closer integration with Silverlight and .NET Framework 3.5 SP1. What’s new in CTP2: Projection. It is new feature for Astoria which has appeared only in this CTP. This feature allows to build more difficult...( read more ) Read More...

I will be speaking tomorrow at the South Florida Architecture User Group (ArcSig) . The session is titled From SOA to WOA: Introducing Web Oriented Architectures and touches upon the fundamental principles and architecture techniques that can help developers to implement distributed systems that leverage the principles of REST. If you are in the South FL area and you are interested on SOA, REST, WCF, etc…please attend to my session. I promise to keep things interesting ;)...( read more ) Read More...

Transactions has typically been one of the aspects that the WS-* followers continuously point out as one of the weaknesses of the REST model. Even though we all agree that atomic transactions in distributed systems are JUST A BAD IDEA and everybody that follows Werner Vogels's lectures knows that the eventually consistent model is the way to go, we can't deny that transactions (conceptually) are an important part of everyday's business processes. However, let's just all be on an agreement that conceptual...( read more ) Read More...

Declarative Services is one of the new features included in the .NET framework 4.0. In a nutshell, declarative services are WCF services modeled and implemented entirely in XAML. This feature is fundamentally enabled by extending Windows Workflow Foundation (WF) 4.0 with the capability of modeling WCF contracts using XAML. You can read more details about declarative services on the MSDN documentation . Even if you are not entirely familiar with WF as a technology, I am sure you can see the advantages...( read more ) Read More...
