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...
לפני מספר חודשים נפתחו באתר מיקרוסופט MSDN ישראל פורומים לפיתוח ו-IT. בחודש האחרון חל שינוי בפורומים, בקטלוג שלהם, וברשימת מנהלי הפורומים. כחלק מהשינוי אני שמח לבשר לכם על פתיחתו של פורום חדש לתחום הווב בניהולם של שלמה גולדברג (הרב דוטנט) ועבדכם הנאמן. בפורום ננסה לתת מענה לשאלות בנושאי פיתוח לעולמות הווב של מיקרוסופט – ASP.NET, ASP.NET MVC, Web Services, WCF, IIS, HTML/JS ועוד. להבדיל מהפורומים של MSDN, הפורומים במיקרוסופט ישראל מיועדים לקהל הישראלי, כתובים בעברית, ומעודדים כתיבה בעברית של שאלות...
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...
If you are not familiar with our user group, the Israeli WDC user group is a meeting place for web developers, designers, and architects, where we discuss new and existing web technologies, best practices in web development, and any other interesting stuff that relates to the web world. The user group is managed by Gal Kogman and yours truly, with the support of Microsoft Israel. This is just a short list of things we talked about in previous meetings: ASP.NET MVC Win8, HTML5, and JS libraries jQuery...

Today I had my WebDev session about the new technologies related to web development: ASP.NET MVC 3 Razor view engine jQuery NuGet IIS Express 7.5 I enjoyed the session very much, and by the amount of tweets it looks like I wasn’t the only one. I hope no one got hurt from my flying balls You can download the session’s slides and the two demos I showed from here: http://bit.ly/vslive-2011-redmond I’m off to San-Francisco tomorrow for the North-America MCT summit . Visual Studio Live – thanks for having...
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 seventh post in the WCF 4.5 series. In previous posts we’ve examined two new security features of WCF 4.5 and IIS – multiple client credentials support, and default HTTPS endpoint support, both new features are IIS-specific (or to be more exact, web hosting specific). In this post we will look into a new security configuration option in WCF 4.5 – the BasicHttpsBinding. 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...
This is the sixth post in the WCF 4.5 series. In the previous post we’ve discussed new authentication features for services hosted in IIS, and this post is continuing the new IIS hosting features list - automatic HTTPS endpoints in IIS.

This is the fourth post in the WCF 4.5 series, and a direct addition to the previous post, since I neglected to mention something important about editing configuration files in WCF 4.5 and Visual Studio 11 – validations during editing and compilation.
