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 improve Web application. We saw how to work with the session list, use...
If you’ve been checking my blog in the last couple of weeks, you might have noticed I haven’t been posting much. In the past two months I have been traveling around the world, speaking in conferences and local user groups. So to sum up this intensive, fun times, here’s a list of all conferences I visited and links to all the material I showed. What’s new in WCF 4.5 Building scalable, low-latency web apps with Windows Azure Embracing HTTP with the ASP.NET Web API You can download the slides and code...
A couple of weeks ago (around Feb. 16) the WCF WebAPIs - a framework for building RESTful/Hypermedia/HTTP services, which was in development over the past 1.5 years as a side-project on CodePlex , has been formally integrated into ASP.NET and its name changed to the ASP.NET Web API. These past two weeks, there has been a lot of questions among WCF developers: What does it mean that the Web APIs are no longer a part of WCF – is WCF dead? Has SOAP gone bankrupted? is HTTP the new way to go for interoperability...
This is the 11th post in the WCF 4.5 series. The previous post was about the new UDP transport support, and this new post is also about new transports – the WebSocket transport. This post is part 1 of 2. This post will be about the WebSocket support between .NET apps using WCF (SOAP-based), and the next post will be about using WebSockets between browsers and WCF (non-SOAP). Previous posts: 1. What’s new in WCF 4.5? let’s start with WCF configuration 2. What’s new in WCF 4.5? a single WSDL file 3...
This is the tenth post in the WCF 4.5 series. I’ve started this series of posts 4 months ago when .NET 4.5 developer preview was announced; The Beta/RC/RTM version is still to come, but hopefully it will be available soon, and you will be able to use the new WCF 4.5 features in your projects. Until now, I’ve shown new features in configuration easiness and hosting improvements. In this post and the next one I will cover new transport features, starting with the support for the UDP transport. Previous...
I was asked yesterday in the Hebrew C#/.NET Framework MSDN forums a tough question – is it possible to dynamically call a WCF service using only the contract name, operation name, and metadata address? At first I agreed with the answer given in the forum – move from SOAP bindings to WebHttpBinding (“REST”). This of course makes things a lot easier, only requiring you to create a WebHttpRequest and parse the response. However the question remains - is it possible to do this in the case of a SOAP-based...
Today I answered a question in the Hebrew MSDN forums about consuming WCF from a .NET 2 client, using the “Add Web Reference” option of Visual Studio. Just in case you don’t know Hebrew I’ll sum it up for you – when adding a web reference to a WCF service that exposes a method of the following sort: int UseScalarTypes( int value1, int value2) The generated method signature in the client app will look like so: public void UseScalarTypes( int value1, bool value1Specified, int value2, bool value2Specified...
As promised in my previous post , I’m continuing my mission to inform you of new changes in WCF 4.5. This is the ninth post in the WCF 4.5 series. This post continues the previous posts on web-hosting features, and this time it is about the improved streaming capabilities of WCF when it is hosted in IIS. Previous posts: 1. What’s new in WCF 4.5? let’s start with WCF configuration 2. What’s new in WCF 4.5? a single WSDL file 3. What’s new in WCF 4.5? Configuration tooltips and intellisense in config...
If you’ve been wondering where I disappeared to in the last couple of weeks, and if you are still waiting anxiously for my next post about WCF 4.5, fear not, I’m here, I’m alive, and I’m still kicking. It’s been quite a rough month, as I have been occupied knee deep in home renovations. If you’ve ever dealt with contractors, technicians, and handyman, you know the type of frustration I’m talking about. Between re-tiling my floors, replacing my kitchen cabinets, and re-painting my entire home, I also...
Yesterday I had two session in VS Live, one about the new features of WCF 4, and the other about the new way to develop web applications using ASP.NET MVC, the Razor view engine, jQuery, and IIS 7.5 Express. The slide decks and demo code for both sessions can be downloaded from here: http://bit.ly/vslive-2011-orlando I really enjoyed delivering both sessions, and congratulations to all the people that won Angry Bird balls for answering my questions, and for asking tough questions. Hopefully we will...
Lately I’ve been writing and speaking a lot about WCF 4.5, but while delivering my “What’s new in WCF 4” session in Visual Studio Live yesterday I realized that there is one feature of WCF 4 that most people are not aware of, and do not really understand how useful it is – Standard Endpoints. In WCF we always have to specify a set of address+binding+contract (ABC) for our endpoints. If our endpoints also need to be configured, for example – change the binding configuration, or the endpoint behavior...
Today I delivered a half-day talk about WCF on the following subjects: The new features of WCF 4.5 We talked about configuration simplicity, WebSocket and UDP support, streaming fixes for IIS, binary compression, and more. Monitoring and troubleshooting WCF services (WCF 3.5/4/4.5) We talked about performance counters, ETW, WMI, AppFabric, sniffing tools, tracing and message logging, instancing, concurrency, load tests and more. According to the events website at http://events.microsoft.com , it...
Yesterday I had my WCF 4 session in VS Live, where I showed some of the new features of WCF 4, including: Configuration simplification IIS hosting features WebHttp improvements Routing services Discovery services I also talked a bit about some other new WCF 4 features such as the DataContractResolver type, the new ReceiveContext API for MSMQ bindings, Monitoring WCF with ETW and PerfMon, the new binary stream encoder, and the new throttling defaults. Those of you who stayed till the end also heard...
This is the second post in the WCF 4.5 series, and this time we’ll talk about WSDL files. Previous posts: 1. What’s new in WCF 4.5? let’s start with WCF configuration A few weeks ago, I posted about the difference between exposing the service metadata through WSDL and through a MEX endpoint. One of the things I noted in the post was that the metadata exposed through a WSDL file is actually one part of the overall metadata – in addition to the WSDL file, there is usually an additional set of files...
This week the new version of .NET was revealed at BUILD – .NET 4.5, and with it also the new version of WCF – WCF 4.5 There are many new features of WCF 4.5, most of them intended to make your life easier when configuring and hosting services, and some other to support features that we all waited for, such as UDP transport support and compressed binary encoding. So what will be the first new feature to explore? why configuration of course, the thing that troubles all WCF developers. Ever had the...
