  • Making WCF Web Async Apis

    One of the hidden gems that you can get today from the WCF Web Api source code in codeplex ( is the support for the task-based asynchronous model introduced in .NET 4.0. The new model simplifies a lot the way you do asynchronous stuff in .NET, and it’s going to get even better with the async support in C# 5.

  • Interop Bindings for WCF released in codeplex

    I am happy to announce that one of the projects in which Microsoft and Tellago have been collaborating together during the last few months was released as part of The primary aim of this “WCF Interop Bindings” project is to simplify the work needed for making WCF services interoperable with other service stacks like Oracle WebLogic, IBM Websphere, Metro or Apache Axis. 

  • Extending the SO-Aware repository with custom metadata

    One of the main features that SO-Aware provides is the central repository for storing service artifacts (WSLD, schemas, bindings) and configuration that any organization generates. This central repository is completely exposed as an OData service that third party applications and tools can easily consume using Http.

  • Second round of Web Http Caching

    As I discussed in my previous post, web caching relies on specific headers that you need to use correctly on your services. That’s an http application protocol thing, and something that you can easily use in any application framework that treats Http as first citizen. This means that you don’t need to implement anything fancy or exclusively rely on an specific caching technology or components for doing ouput caching (e.g ASP.NET Cache).

  • Implementing caching in your WCF Web Apis

    One of the beauties of using Http as application protocol when building Web Apis is that you can reuse all the available infrastructure in the web to make your services scalable to the extreme. Caching is one of the fundamental aspects that makes scalability possible in the web today because it provides the following benefits when it is implemented correctly,

  • Configuring your WCF Web Apis

    Another major improvement in this new WCF Web Api release is the introduction of a fluent API for configuring your WCF Web Apis. All the available extensibility points in the current bits are now exposed through this API making possible to easily discover them.

  • Http Message Channels in WCF Web Apis Preview 4

    The new WCF Web Apis Preview 4 released yesterday in the introduced a new extensibility point for intercepting messages at channel level. The name for this new feature is “Http Message Channels” and the good thing is that you don’t need to rely anymore on the REST Starter Kit request interceptors for doing the same thing. Actually, a Http Message Channel is more useful as you can intercept either request or response messages, and also you get an Http message with all the context information you might need and not a WCF generic message, which usually requires some additional processing.

  • Troubleshooting your WCF Web Apis with AppFabric

    In this last post, I showed how the new WCF Web Apis could be integrated with AppFabric for pushing custom events to the AppFabric tracking database. A great thing about the monitoring infrastructure in AppFabric is that is uses ETW as mechanism for publishing the events, so your services are not hitting the database directly with all the performance penalties that database calls imply.
