51 of 3325 | Please authenticate - For the past 3 days, I’ve been engrossed in finishing an IE8 accelerator for my pet project codenamed as Arc Reactor. The IE8 Accelerator is simply known as Arc Accelerator. None of these names are final yet, as my team mates and I are still deliberating what will be the actual name of this project. Anyway the Arc Accelerator is meant to allow users to select a chunk of text in IE8, and save it as a tag. The saved tag can be populated into a “tag cloud” (again no actual name decided yet) maintained by the Arc Reactor client, which is developed as a WPF application. In order to save the tag, a “session” of some sort needs to be created. It needs to be persistently stored (at least until a......

53 of 3325 | Testing WCF Service Apps (Part 1 of 4) - Previous posts: Part 0 of 4: Introduction Testing the Service Of the four posts, testing the service is by far the easiest. One of the most beautiful things about the WCF framework is the way it was designed to be more testable than ASPX services.  When you design your WCF interface, you are mostly just designing an interface with the WCF ServiceContract attributes.  The WCF framework uses your interface to determine the actual contract and transport mechanism so you don't have to.  This is the key to testing WCF services:  YOU DON'T HAVE TO WORRY ABOUT THE WCF FRAMEWORK.  This means that you can simply instantiate your service directly and start calling public methods on it.  You ne......

54 of 3325 | Troubleshooting a DCOM issue: Case Study - Hi all,this is my first post after a LONG LONG time since I created the (so far empty) blog. I guess it is not by coincidence that last night it snowed in Milan . Let's get started with the case study at hand. In the Distributed Services team in Microsoft Developer Support we support technologies for developing distributed systems, including DCOM/COM+, Distributed Transactions, Windows Communication Foundation (WCF), Workflow Foundation (WF), CLR COM Interoperability, and more. This case study refers to a DCOM problem which I have been handled recently. The purpose is not only to go into some details on how some pieces of DCOM work, but also to show a troubleshooting strategy for these type......

55 of 3325 | Correlation under the Hood - You'll probably want to have read the previous articles about correlation for this to make sense. Future of Correlation Future of Correlation Examples Message Filters and Queries Now that you've seen some of the details about message queries, you can combine queries with Ed's demonstration of programming a correlation in workflow to infer how the system actually works. In a workflow program, correlations are described by placing send and receive messaging activities that are associated by a shared correlation handle. Each of the messaging activities has attached correlation queries that help define the application protocol. The correlation queries are just examples of que......

56 of 3325 | WWSAPI to WCF interop 5: WSFederationHttpBinding with mixed mode security - WCF endpoints with WSFederationHttpBinding accept SAML tokens issued by trusted Security Token Services (STS, the Issuing Party, or IP). The first thing that should be noted with WSFederationHttpBinding is that secure conversation (specifically, the February 2005 version) is turned on and no knob is provided to turn it off (in fact, this is the case for WS2007FederationHttpBinding in .NET 3.5 as well). WSFederationHttpBinding has three security modes: None, Message, TransportWithMessageCredential. In Win7, WWSAPI will only provide support compatible to the TransportWithMessageCredential mode.   First of all, in order to send a SAML token, the client has to obtain such a token. For a ......

57 of 3325 | Dublin Webcasts - I’ve posted a couple of webcasts on Dublin on BloggersGuides.net. They are based on the PDC08-CSD image, so things may well change going forward, but they provide a good intro as to how to get started exploring hosting services in Dublin, and the configuration options. Hosting Workflow Services in Dublin This webcast will look at hosting declarative services in the Dublin application server. The webcast will start with a basic WCF declarative service and demonstrate the procedure to host the service in Dublin. The configuration features in Dublin will be explored, including tracking, persistence, and throttling. The tracking data will be queried using SQL Server Management Console, and t......

61 of 3325 | Using MapPoint-Services with Dynamics Ax 2009 (workaround for the missing generated CSharp files) - Consuming MapPoint Web-Services with Dynamics Ax 2009 is unfortunately not very easy since Dynamics Ax 2009 suffers of the same limitation as Visual Studio 2005: It creates only one Service-client per WSDL file. Normally, since it’s a standard Web-Service and Microsoft added in Dynamics Ax 2009 the WCF, it should be enough to add the service reference to your AOS and you can start developing (a little bit simplified, but Cesar showed , that it does not need more than that). You can find the WSDL...(read more)...

62 of 3325 | Anatomy of a Subtle JSON Vulnerability - I recently learned about a very subtle potential security flaw when using JSON. While subtle, it was successfully demonstrated against GMail a while back. The post, JSON is not as safe as people think it is, covers it well, but I thought I’d provide step-by-step coverage to help make it clear how the exploit works. The exploit combines Cross Site Request Forgery (CSRF) with a JSON Array hack allowing an evil site to grab sensitive user data from an unsuspecting user. The hack involves redefining the Array constructor, which is totally legal in Javascript. Let’s walk through the attack step by step. Imagine that you’re logged in to a trusted site. The site makes use of JavaScript which makes......

63 of 3325 | How to configure database mirroring between 2 instances on a standalone server - There are lots of troubleshooting articles about how to diagnose connectivity problems when setting up database mirroring, especially errors such as these: Msg 1418, Level 16, State 1, Line 2 The server network address "tcp://mirrortest.com:5023" can not be reached or does not exist. Check the network address name and that the ports for the local and remote endpoints are operational. or Msg 1456, Level 16, State 3, Line 1 The ALTER DATABASE command could not be sent to the remote server instance but here's something a little different.

64 of 3325 | Introduction to Geneva - Setting up the server - Last week at TechEd I followed a couple of presentations on Geneva, the project that used to be called Zermatt. Geneva is a series of components that will make it a lot easier for developers to work with identities within their applications. It's build up from three components: Geneva Server: a security token service (STS) that will be responsible for supplying the identities. Geneva Framework: a new part of the .NET framework that will handle all of the plumbing in dealing with these identities. Geneva Cardspace: the client technology that will make it easier for users to reduce and handle the identities that they have to use. The are a couple of things about Geneva that make it ver......

66 of 3325 | Message Filters and Queries - Since a message filter and message query share a similar heritage, let's start by looking at the conceptually simpler message filter APIs. You probably haven't seen message filters before unless you've gone out of your way to explore everything that comes with WCF. They don't appear in the ordinary use of web services. A message filter is basically a matching delegate that works on WCF messages. There is not a lot of interesting message filter methods. public abstract class MessageFilter{ protected internal virtual IMessageFilterTable<FilterData> CreateFilterTable<FilterData>(); public abstract bool Match(Message message); public abstract bool Match(MessageBuffer ......

71 of 3325 | Expression tree serialization code posted on Code Gallery - Luke and I worked on this last year for one week doing pair programming. It is a good sample of how you can serialize LINQ expression trees to xml. The sample includes these components: An Expression Tree serialization API: A general purpose XML serialization of Expression Trees. This should work over any expression tree – though there are inevitably bugs. The serialization format is fairly crude, but has been expressive enough to support the variety of expression trees I’ve tried throwing at it. A wrapper for serializing/deserializing LINQ to SQL queries: A wrapper around the expression serializer allows serializing LINQ to SQL queries and de-serializing into a query ......

72 of 3325 | Future of Correlation Examples - Last time I talked about how WCF 4.0 standardizes many different types of correlations using a query mechanism and promised to go into more detail today. You might already be familiar with the message filter engine in WCF 3.0. If you haven't seen message filters before, then the message filter engine is just a way to check for matches in a message. For example, you might have an implementation of a message filter that uses XPath expressions and then create the filter /s:Envelope/s:Body/x:FooRequestMessage/y:OrderId to match SOAP messages with a particular structure. Instead of using an XPath to match the message content, you might instead have used an intrinsic function to match a m......

74 of 3325 | N-Tier Improvements for Entity Framework - The first version of Entity Framework provides convenient ways to load, manipulate and persist objects and relationships. As with many other O/RMs, Entity Framework has a state manager that tracks every change made. Existing objects are typically loaded first from the database, later modified, and finally the changes are saved back to the store. Another feature, full graph serialization, makes it very easy for developers to ship around object graphs representing snapshots of the current state of the world, across execution boundaries. The next version of Entity will also support Persistence Ignorance. Therefore object graphs can now be made of POCO instances, which WCF now also suppor......

78 of 3325 | Step by Step: Working with Content Based Correlation in Workflow 4.0 - Don't miss the screen cast video on this same subject available at Content Based Correlation in Workflow 4.0 Content based correlation is used when you send a message out of a long running workflow and need to get a response back later into that same workflow using information contained inside the original message.  In this case, the correlation needs to be stored and made available to match the response message. Content based correlation is easy to set up and use inside Windows Workflow 4.0.  At a high level you need to do the following: Create a Correlation Handle variable to use for the correction Set up this variable and xpath on the Send Activity Set up this variable ......

79 of 3325 | Design: SOA Taxonomy, an object oriented approach - This interesting post by Salvador explores the topic of SOA Taxonomy.  An essential part of the SOA Governance is to properly identify the requirements in order to introduce or upgrade a service within your SOA model, this is commonly known and service and integration planning within the SOA lifecycle. This is all good in theory but the nightmares start when architects are trying to put it in practice. As an application development consultant here at Microsoft we constantly find chaos in the SOA first attempts, the main reason behind this is the lack of services organization. This not only brings problems to the model that are expensive to change but does not shows business val......

80 of 3325 | Future of Correlation - One of the topics that you'll hear a lot about for asynchronous and decoupled programming in WCF 4.0 is correlation. Correlation is a relationship between one message and another message or one message and a piece of state. With synchronous programming, you may not always think about the correlations that are present. Correlations may be implicit through a call stack or through local variables. Or, they may be dramatically simplified by virtue of the fact that you know what's going to happen next and can craft your code to match the situation. In asynchronous programming, correlation is the glue that joins together different operations. There are many different types of correlatio......

81 of 3325 | MARK YOUR CALENDARS: Part 10 of Windows Mobile Application Development Series is coming up on November 19: Windows Networking - Please join us for part 10 of our 24-part Webcast series on Windows Mobile Application Development. This week, Andy Wigley, co-author of the Windows Mobile Development Handbook, will talk about networking. In this webcast, you learn how to create a network connection in code and how to discover if you have network connectivity. We look at the design of applications that need to be network aware and strategies for creating applications that can operate when disconnected from the network and then sync up data when network connectivity is restored. We also compare the options for transferring data over a network connection, which include ActiveSync, Microsoft SQL Server merge replication, remo......

84 of 3325 | Publishing WCF web services for Silverlight. - As a self-confessed crayon wielder I tend not to get involved in the washing machine technology of web services.  I am normally a consumer only and when I do have to write a web service it has only been part of prototypes or proof's of concept. The current project I am on required something a little more.  We were required to develop and publish a web service that could be consumed by a Silverlight application from our live site. The development process was fairly easy. Deployment not so. You'll probably have noticed that when developing a WCF service, when you view the service in a browser you get something like this. You'll notice that 'localhost' is returned for the hos......

85 of 3325 | Testing WCF Service Apps (Part 0 of 4) - When you are writing automated tests for your application, it is important that the tests do not rely on the file system or external services.  The only problem is that when you write applications using WCF, you are writing code that relies on external services.  It is very tempting to create service references in your test DLL and test against them, but please refrain.  There is a better way, I promise! This series will focus on testing every part of your application -- including round-trip functional tests -- without employing the WCF framework directly.  We need to remember that the WCF framework is code that we do not control.  We need to trust that it does what it claims to and focus ......

86 of 3325 | What books should I buy for CSLA .NET? - As the Expert C# 2008 Business Objects book becomes available (now in alpha ebook form, and in paper by the end of this year), I'm getting more questions about what book to buy for different versions of CSLA .NET, and for different .NET technologies. (Expert VB 2008 Business Objects should be out in February 2009. The one unknown with this effort is how quickly the team of volunteers can get the VB port of CSLA .NET 3.6 complete, as I don't think we can release the book until the code is also available for download.) I do have a summary of book editions that is often helpful in understanding what book(s) cover which version of CSLA .NET. But I thought I'd slice and dice ......

88 of 3325 | MSI Import - Phantom Binding - Had an error today when attempting to import a BizTalk MSI through the Admin Console. It was complaining that a particular adapter had not been configured to work with a particular host. Indeed this was true, however what puzzled me was that there was no refernce to this host in the binding file which had been added to the MSI.   After a fair amount of head scratching I tracked back to the orchestration that contained the logical port which matched to the physical port (SOAP) that was mentioned in the error message. It seems that the problem was caused by the fact that the binding on the logical port had been inadvertently set to 'Specify Now'. It seems that this cause a physical port t......

90 of 3325 | WWSAPI to WCF interop 4: WSHttpBinding with username over transport security - WWSAPI doesn’t support full message mode security (where security negotiation happens at SOAP message level and parts of the envelope are signed and encrypted using XML signature and XML encryption) in Win7 time frame. This means the default WSHttpBinding is not interoperable with the WWSAPI’s security offering as the WSHttpBinding defaults to use full message mode security with secure conversation. WWSAPI supports mixed mode security that provides message integrity and confidentiality at transport level (e.g. through https). In mixed mode security, the client is authenticated through a token carried in the SOAP message’s security header. Client credential types supported by WWSAPI in Win7 ......
