5 of 3754 | Setting up SSL between Silverlight and WCF under IIS7 - I was building a Silverlight 2.0 application for a Tricension client and determined that it was appropriate to utilize SSL to secure the site.  In particular, to secure communications back-and-forth between the WCF services which were handling a lot of sensitive financial data.   Although I had setup SSL on several sites before, I didn't realize how difficult it was to find a good reference on how to do this for WCF.  After a very long day, thought I'd share how I got this to work.  Of course, now that I know, it's not that tough. Step 1 - Install your SSL Certificate I'm not going into the details on how to setup SSL in IIS7 here other than to say GoDaddy.com is awesome.  They're cheap (......

7 of 3754 | Posting the source code for my #mix09 talk - I just posted the source code of the demo applications I used in my MIX09 talk "Working across the client continuum". The source code is structured as follows: DotNetContinuum: This solution contains the following projects: DotNetContinuum: a WCF service configured with 2 endpoints (SOAP and JSON), as well as 3 client applications: DotNetContinuum.Mvc: An ASP.NET MVC application showing a "pure" ASP.NET MVC application enhanced with AJAX content.

8 of 3754 | Resolving WCF Fatal Execution Engine Error... - I haven't seen many "Fatal Execution Engine Error (79FFEE24)" sorts of messages lately - not since .NET 1.0/1.1 days. But we were wrestling with an issue for multiple weeks in which a WCF service would crash with exactly this error.  Since this service uses the DataContractSerializer, this post seemed quite relevant.  The workarounds suggested there were not going to be a fit for us, unfortunately. The really insidious part of this problem was that the initial failure mode was causing a third party library (that our service invoked) to fail...complete with a stack trace that pointed deep into the third party code.  However, when we removed the call to this library......

11 of 3754 | BizTalk WCF Custom Adapter – Developing WCF Custom Behaviours - As you sink your teeth into the depths of BizTalk 2006 R2/2009 and realise the potential of integrating with the WCF Custom Adapter, a new world opens up. Then… Then at one point down the track you’ll want to tweak or customise what is being sent/received. For e.g. changing the shape of the XML transferred over a HTTP transports – maybe compression, maybe minus the explicit XML notation (i.e. takes 5KB to send over 30 chars) So you’ll then move onto something called a WCF Custom Behaviour.

13 of 3754 | I will be speaking in Stockholm on Oslo - [Even though it may have been more appropriate to speak on Oslo in Oslo? :)]   Next month I will be speaking at the Cornerstone Developer Summit in Stockholm, Sweden. I will be doing 2 sessions, one on M, the other on the new wave of Microsoft SOA offerings (Oslo, BizTalk, Dublin, Azure, .NET 4, et al) and how things fit together from an architectural perspective. I’m looking forward to this event, I hear it’s a top-notch event and always a lot of fun, and I’m looking forward to catching up with a couple of my old friends Julie Lerman and Scott Bellware. I’m also trying to get to the local BizTalk user group where MVP Alan Smith and I will present a BizTalk Best Practices session.   To......

14 of 3754 | My Book "SOA Patterns with BizTalk Server 2009" is Up for Pre-order - Well look at that.  I just happen to check my publisher’s website today and noticed that they put my book description online and made it available for pre-order. The book, entitled SOA Patterns with BizTalk Server 2009, is due out by May 2009 (hopefully sooner).  I’m still in the process of editing the book and responding to technical review comments, but we’re nearing completion of that phase.  I have three fantastic technical reviewers (Charles Young, Zach Bonham, Ewan Fairweather) who have added a ton of great comments that I’m almost done wading through and addressing. This publisher (Packt Publishing) specializes in short, targeted technical books that address specific topics.   I trie......

19 of 3754 | ASMX, WCF and enums woes - We’ve been slowly migrating our services from asmx to WCF, but as we’re still using BizTalk 2006 with no support for WCF we’ve been exposing endpoints configured for basicHttpBinding and consume them using the SOAP adapter. Generally speaking things have been going well, although we completely gave up on the idea of moving the services to WCF and NOT have to change the client, until yesterday we’ve stumbled into a serialisation issue – The SOAP adapter, as part of its work deserialises the request message arriving through the send port into t he web service proxy class it generated, before calling the web service (which would result in the class now being serialised back into xml, which is......

20 of 3754 | Easy Installation of Visual Studio 2008 extensions for SharePoint (VSeWSS) 1.3 - The new version of the Visual Studio 2008 extensions for SharePoint 1.3 include some changes to support install on x64 OS. Specifically it creates a WCF web service that is required to run in x64 and communication with x64 SharePoint. The x86 Visual Studio 2008 makes calls to this web service to do certain SharePoint operations. The web service is secured so it can only be called by Visual Studio 2008 running on the same machine. We also do not automatically give the web service the required permissions to make calls into SharePoint. The installer notes this, but it's easy to overlook, that you have to add these permissions. Steve Fox just wrote up a great screen shotted guide for how to ......

22 of 3754 | WCF -> JSON Serialization woes and a solution - I'm working on improving the performance of my current web application project at various points. As I had already planned for a WCF interface for third-party use, I thought I'd utilise that, exposing objects as JSON-serialized strings usable by jQuery/ASP.NET AJAX. Little did I realise that when I was coming up with my Data Framework (I chose Entity Framework) I should have thought about aspects at the other side of my project such as the User Interface as well as the more obvious aspects of scalability, performance in relation to a pragmatist view of what is needed in the "real world" (therefore, nHibernate is out). My WCF service had an exposed service that would retu......

24 of 3754 | HttpClient makes query strings & form input a breeze - The WCF REST Starter Kit Preview 2 provides several classes for managing traditional query string and form input to RESTful services:  HttpQueryString, HttpUrlEncodedForm, and HttpMimeMultipartForm.  These make passing data into RESTful services much easier. Here's an example using HttpQueryString:HttpClient http = new HttpClient("http://twitter.com/statuses/"); http.TransportSettings.Credentials = new NetworkCredential(username, password); HttpResponseMessage resp = null;// add query string variables HttpQueryString vars = new HttpQueryString(); vars.Add("id", screenname); vars.Add("count", count); resp = http.Get(new Uri("user_......

27 of 3754 | Thoughts about BizTalk VNext - Recently a few of us were speaking about what would be the future of BizTalk after the 2009 release. I already had a few thoughts on what I think would be great additions to the product and what strategic directions it may move in. I have checked to ensure that none of my thoughts breach the MVP NDA and after getting the thumbs up I've listed my thoughts below so there might be a bit of discussion on these ideas.

30 of 3754 | Silverlight 2 Book Reviews - I wanted to share a couple of suggested Silverlight 2 reads, especially for those visiting my blog after the recent Winnipeg Code Camp talk I did on Silverlight 2. Pro Silverlight 2 in C# 2008 by Matthew MacDonald. This book is an incredible reference, covering almost every topic that you’d need to know for building Silverlight 2 applications (There’s no dedicated “Architecture” chapter, but I think that’s a topic best served currently by the Microsoft P&P Team and Prism). The book has the benefit of being printed in color, which at first I thought was just a gimmick to sell more books…but y’know, seeing sample screens in color is actually an enhancement. I’ve read another Sil......

31 of 3754 | WCF Exception: "There can be at most one address per scheme in this collection" - I'm beginning to see why people dislike WCF.  I'm working on using WCF to feed an AJAX TreeView, and demos of it are FAST. However, in my debugging on my dev server I bumped into the exception: "There can be at most one address per scheme in this collection" The posters at http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/9e248455-1c4d-4c5c-851c-79d9c1631e21/#page:1 seem to be most vocal about the definiciencies of WCF in this respect - and they'd be right. What were Microsoft thinking? Most web applications need to respond to at least two domains to overcome the vagaries of user-inputted URLs, eg: www.myapp.mysite.com mapp.mysite.com my......

After taking a two-years-and-a-bit hiatus from the cutting edge of technology, I'm now about to return full time. But before we're back to the regular program, let me answer the question inevitable question: what was up with you?? What happend was that I've had the pleasure to find a few really amazing clients and decided to work with them on some of their medium/longer-term projects (longer term meaning substantially more than the usual three-day-visit to a client to help them with a particular issue or question they might have).

49 of 3754 | A Gotcha Writing Messages - I’ve been working a lot with low-level contracts in Windows Communication Foundation that send and receive raw System.ServiceModel.Channels.Message objects. These are fairly flexible, though the API can be a bit confusing. One of the things I was doing was making sure I was doing proper streaming of large messages, which in WCF relies on the XmlReader and XmlWriter classes. What is not be very obvious at first is that it is possible to receive a Message object and still do streaming: Basically when the received message is created, it takes an XmlReader that is only consumed when you ask WCF to write the message to an XmlWriter.
