The Problem Solver - Sunday, May 12, 2013 Why Does WCF Reject Large Messages By Default? 'If you have been working with WCF for a while you may have noticed that, by default, messages over a certain size fail to get processed. The reason for this is that WCF tries to protect the message receiver from getting swamped with messages that will consume huge amounts of memory to process. Once the binding allows messages larger than 64Kb that may not be the whole story as there are other default limits in WCF: quotas and serializer limits.

DevelopMentor Courses - Friday, February 4, 2011 Ninject WCF Extensions for RESTful Services while ago I blogged about using Ninject for dependency injection with WCF Services. The problem with WCF services is that by default they are required to have a parameterless constructor, which does not play nice with DI containers, such as Ninject , which support injection of dependencies via constructor parameters. had the need recently to set up a REST-style WCF Services project and wanted to use Ninject for DI with it. Luckily, the Ninject WCF Extension project had been updated to support REST, so I updated the Nuget package and discovered the project would not compile. DevelopMentor Courses - Sunday, April 8, 2012 Roll Your Own REST-ful WCF Router Recently I’ve been tasked with building a WCF routing service and faced the choice of whether to go with the built-in router that ships with WCF 4.0 , or to build one from scratch. However, as the MSDN documentation for the WCF Router states, “ The Routing Service does not currently support routing of WCF REST services. In fact, using the BasicHttpBinding with AspNetCompatibility enabled on the built-in WCF router results in a somewhat cryptic error : “Shouldn’t allocate SessionChannels if session-less and impersonating.”. Technical WCFEnjoy. DevelopMentor Courses - Tuesday, April 24, 2012 | - Building Scalable and Secure WCF Services
The key to building scalable WCF services is to eliminate binding configurations that could result in server affinity. Nevertheless, there is one wrinkle: by default the WCF HTTP bindings enable Keep-Alive , which can result in server affinity and thereby impede scalability in a load-balanced environment. The problem here is that WCF will not allow you to pass credentials, such as username and password, over a non-secure channel. The trick is to fool WCF into thinking we are using a secure channel when in fact we are not. Technical REST SOAP WCFEnjoy. DevelopMentor Courses - Monday, June 18, 2012 - Secure WCF REST Services with a Custom UserNamePasswordValidator
When securing WCF services you’re faced with a choice: Message versus Transport security. WCF has terrific support for this scenario and allows you to supply a custom UserNamePasswordValidator , which you can use to validate client credentials. The nice thing about WCF is its unified programming model, which allows you to use the same username / password validator for both Soap and Rest clients. Technical REST Security WCFDownload the code for this blog post here. You’ll need to set the security mode of the basic HTTP binding to “TransportWithMessageCredential.” DevelopMentor Courses - Monday, May 28, 2012 - The Architecture of WCF
'Before WCF it was, of course, possible for software running on different machines to communicate. The goal of WCF was to provide a unified API for communication and to be able to provide a common level of service irrespective of the underlying transport. To understand the structure of WCF and why it looks the way it does useful starting point are the four tenets of service orientation. There are three core concepts at play whenever you use WCF: messages, channels and encoders. Message is a first class construct in WCF and are modeled on SOAP messages. DevelopMentor Courses - Sunday, April 7, 2013 - Certificate Validation and Setting up Service Bus 1.0 Beta for Windows Server
With these in place the Getting Started / Brokered Messaging / QueuesOnPrem sample should work fine.NET;Azure;ServiceBus;WCFMicrosoft recently announced the beta of Service Bus 1.0 for Windows Server. This is the on-premise version of the Azure Service Bus that so many have been asking for. There is a good walkthrough of the new beta in the MSDN documentation here including how to install it. So why this blog post? First a little background into why there is an issue. In fact the issuer of the issuer must also be trusted. In fact the issuer of the issuer of the issuer must be trusted.

Download the Common Instance Factory with WCF Extensions here and is also available on NuGet. This led me to develop the Common Instance Factory , as an alternative to the Common Service Locator, and to extend it with support for WCF services that are decoupled from any particular DI container. The power of the abstraction comes to the fore when using dependency injection with frameworks such as ASP.NET MVC or WCF. Technical DI WCFIn this example, an IGreetingRepository is passed to the GreetingService’s constructor. Ah, but there’s a problem. Stay tuned for more!) DevelopMentor Courses - Wednesday, May 23, 2012 - Decouple WCF Services from their DI Container with Common Instance Factory
This layer of abstraction can be especially advantageous, for example, when building ASP.NET apps or WCF services where performance is a critical factor. The NuGet package, CommonInstanceFactory.Extensions.Wcf , provides the building blocks for hosting WCF services which are decoupled from a particular DI container. The first component is the InjectedInstanceProvider , which implements the WCF interface, IInstanceProvider , using ICommonInstanceFactory to retrieve and release instances from the DI container (see my prior blog post for more information on ICommonInstanceFactory).

| The Best from DevelopMentor | MORE | - WCF Duplex Messaging
I am one of the moderators of the MSDN WCF Forum. However, the first three of these are supported natively in WCF and are known as One-way, request/response and duplex. Duplex Contracts in WCF. In WCF this idea is modelled by the contract. WSHttpBinding is the default for the built in WCF projects but it does not support duplex messaging. It will also need to supply this implementation to the WCF infrastructure and it does this by wrapping an instance in an InstanceContext object and passing it to the proxy constructor.

DevelopMentor Courses - Friday, February 4, 2011 - Using Silverlight to Access WIF secured WCF Services
Another technology that comes up very often is Silverlight – and especially the “story” of Silverlight and WCF/WIF. Those of you with WCF background will say: “that’s what the federation bindings in WCF are for”. In WCF you can work around that problem by adding the ValidateMustUnderstand behavior to the client stack. Tags: IdentityModel WCF This topic comes up quite often recently – so I hope the title is search engine friendly. Disclaimer: At the time of this writing, the current version of Silverlight is v3 and WIF is in beta 2. Passive. Active. WSTrust13. www.leastprivilege.com - Wednesday, October 28, 2009 - Inversion of control and WCF
One of these case is with an WCF service where WCF takes care of the service lifetime and creates new objects as needed. Fortunately WCF is designed in a very modular fashion itself and allows you to replace almost everything in the box. Basically WCF uses an implementation of the IInstanceProvider to create new service objects.

The Problem Solver - Tuesday, April 19, 2011 - Digging into WCF REST
Last Thursday evening I presented a talk to the Dallas.NET User Group on support in WCF 4 for building REST-ful services. Building REST-ful Services with the WCF Web Programming Model REST is defined as an architectural style for building services that embrace the principles of the web. He’ll also get down and dirty using the WCF Web Programming Model and show how WCF makes it easy to serve up POX or JSON, increasing the reach of your services to clients that don’t understand or care about SOAP.
