First of all; credits for this solution goes to a former colleague, and now a contractor working in my department; Erlend Rotvik of WebStep Fokus. The title might be a bit cryptic, so let me elaborate a bit on the subject; until last week or so, it was “common knowledge” that using the NetMsmqActivator...

A few folks have been asking if it is possible to serialize/deserialize using the DataContractSerializer. Rest assured, yes it is possible. Now whether or not it is the easiest/most intuitive model well that it is a different question. If you read to the end the post you will see a bunch of extensions...

tempuri.org is the default namespace applied to WCF Services and Workflow Services.  You can and should specify your service namespace. It is recommended that you explicitly specify a name and namespace for the service contract, and an action for each operation to avoid using " http://tempuri...

This post is part of a series about WCF extensibility points. For a list of all previous posts and planned future ones, go to the index page . We’re now entering the realm of the less used extensibility points for the WCF runtime. Operation selectors could well be left as an internal implementation detail...

A few customers have noticed an issue with WCF scaling up when handling a burst of requests. Fortunately, there is a very simple workaround for this problem that is covered in KB2538826 (thanks to David Lamb for the investigation and write up). The KB article provides a lot of good information about...

This post is part of a series about WCF extensibility points. For a list of all previous posts and planned future ones, go to the index page . Message formatters are the component which do the translation between CLR operations and the WCF Message object – their role is to convert all the operation parameters...

This post is part of a series about WCF extensibility points. For a list of all previous posts and planned future ones, go to the index page . The message inspectors, described in the previous post of this series, allows you complete control over the message going through the WCF stack. They’re very...

This post is part of a series about WCF extensibility points. For a list of all previous posts and planned future ones, go to the index page . The message inspectors are probably the most used extensibility points of the WCF runtime. Anytime you need to log, inspect, modify or completely replace a message...

This post is part of a series about WCF extensibility points. For a list of all previous posts and planned future ones, go to the index page . Before starting on the actual extensibility points for the WCF runtime (first post should be online tomorrow), I decided to write this quick introduction to the...

This post is part of a series about WCF extensibility points. For a list of all previous posts and planned future ones, go to the index page . The first behavior covered in this series is the IServiceBehavior . It can be used to inspect or change the entire service description and runtime. For example...

This post is part of a series about WCF extensibility points. For a list of all previous posts and planned future ones, go to the index page . The first part of this series will focus on the behaviors. There are four kinds of behaviors, depending on the scope to which they apply: service, endpoint, contract...

REST is primarily about 2 things, Resources and Representations. If you’ve seen any of my recent talks you’ve probably seen me open Fiddler and how our ContactManager sample supports multiple representations including Form Url Encoded, Xml, Json and yes an Image. I use the image example continually not...

Been a while since our last roundup and since my last blog post for that matter! Fortunately there’s been a bunch of cool stuff going on in the community with our Web APIs that I can point you to. Great to see the community momentum pick up as we cross the 5000 download mark on Codeplex ! Blogs WCF Web...

A little over a month ago we launched our new WCF Web Apis on Codeplex . Since then a bunch of folks in the community (and some internal folks) have been posting about their own explorations / thoughts of the new bits. it’s great to see the work that they are doing! I am going to start aggregating these...

Auto-start is a really cool feature of Windows Server AppFabric. Recently I was asked about how you can do some kind of process initialization in your code with Auto-start (which the documentation implies that you can do). This led to a discussion with a number of questions that we want to address What...

Recently I had a customer email me looking for information on how to send and receive large files with a WCF HTTP service. WCF supports streaming specifically for these types of scenarios.  Basically with streaming support you can create a service operation which receives a stream as it’s incoming...

Do you use WCF within your organization either for internal apis for exposing services and functionality to 3rd parties? We’re looking to connect with customers using our stuff in the real world so we can understand your use cases, the things you’ve liked about WCF and where you’d like to see us improve...

NoWhen I first heard about the new async functionality in C# at PDC 2010 last week, my immediate reaction was; how can this be used to ease the development of asynchronous WCF/WF services (and clients). Well, it turns out that someone on Microsoft has thought about the same thing; in the samples that...

At PDC in my session  “Building Web APIs for the Highly Connected Web” we announced WCF Web APIs, new work we are doing to make HTTP first class in WCF. In this post I am going to describe what we are doing and why. If you are saying, “just show me the bits”, then just head on over to wcf.codeplex...

If you are building for the web and the cloud, then you know that HTTP is important. WCF is no stranger to HTTP. Since .NET 3.5, we’ve been continually delivering capabilities in the platform to enable developers to expose services as resources over HTTP. Now we’re looking to raise the bar several notches...

…at least when it comes to handling of decimal numbers – and it probably goes for all other non-English locales that doesn’t use period as the decimal delimiter. If you look closely at the screenshots below, you’ll notice that I’ve entered 2500,00 – that is two thousand comma zero zero in Norwegian....

I’m taking this week off to catch up on everything I haven’t done the last two months and to celebrate the Thanksgiving holiday here in the US. PDC was a blast!  It was incredibly awesome to meet so many folks interested in WF and talking with others about how they are using (or plan to use) WF4...

Hi, and apologies for being so awfully quiet the last couple of months. Expect the traffic to pick up again (I’ll explain the silence in a blog post later). Now, when unit testing WCF Services, I’ve often ended up with cluttering my tests with a lot of plumbing code to wire up the SUT; that is [...]...
