Calling a WCF service from a client without having the contract(blogs.microsoft.co.il)

submitted by idof(215) 2 days, 13 hours ago

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? The short answer is – YES! To see how, check out the code in the blog post. read more...

WCF/ASMX Interoperability – Removing the Annoying xxxSpecified when Ad(blogs.microsoft.co.il)

submitted by idof(215) 11 days, 14 hours ago

WCF/ASMX Interoperability – Removing the Annoying xxxSpecified when Adding a Web Reference to a WCF Service Today I answered a question in the MSDN forums about consuming WCF from a .NET 2 client, using the “Add Web Reference” option of Visual Studio. Apparently adding a web reference to a WCF service can cause the method signatures on the client side to look different. In this post I explain why that is and how to fix it. read more...

Improve WCF services testability with simple Dependency Injection(blogs.microsoft.co.il)

submitted by roadan(90) 12 days, 23 hours ago

Dependency injection is a great technique to reduce coupling between components and improve testability. Manually injected dependencies are dependencies which are passed manually to an object's constructor. When using WCF we depend on the WCF run time to create new instances of our service class. This solution provides a way to easily control service class instantiation for any type of WCF service read more...

WCF Client Proxy Creation Process(gal-segal.com)

submitted by corneto(135) 13 days, 1 hour ago

WCF enables us to consume a service in 2 ways: adding a service reference or by creating the proxy yourself. Both methods do the same thing – create a proxy class and and using it with the channel factory. Both cases are good, and its a matter of preference which one you use. I tend to use the second one – I prefer creating my proxy and add reference to the service dlls in the consuming app. read more...

Introducing Unity.WCF providing easy IoC integration for WCF services(www.devtrends.co.uk)

submitted by devtrends(184) 24 days, 19 hours ago

There are numerous blog posts available that explain how to hook up Unity with WCF. Unfortunately, many of these are incomplete, too basic or just plain wrong. Additionally, as far as I can tell, nobody has created a NuGet package to get you up and running as quickly as possible. This post introduces Unity.WCF, an open source NuGet package that (hopefully) just works in most situations, deals with cleaning up IDisposable instances and also provides a nice mechanism for automatically adding WCF behaviors to your services. read more...

What’s new in WCF 4.5? Improved streaming in IIS hosting(blogs.microsoft.co.il)

submitted by idof(215) 25 days, 15 hours ago

What’s new in WCF 4.5? Improved streaming in IIS hosting As promised in my previous post, I’m continuing my mission to inform you of new changes in WCF 4.5. If you’ve ever tried creating a WCF service that uses streamed requests (for example a file upload service) and host it in IIS, you may have noticed a strange behavior in your WCF service – it would seem that WCF is late in receiving the request, as if it was entirely loaded into the memory, and then passed to WCF. So is it streamed? or is it actually buffered? well, it’s both. 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 4.5 when it is hosted in IIS. read more...

submitted by vivekamar(5940) 1 month ago

In this post I will show you why this solution is not safe, why you should omit such structures and how to fix them. read more...

Validating WCF services with System.ComponentModel.DataAnnotions(www.devtrends.co.uk)

Two popular methods are manual checking and the Validation Application Block (VAB) from Enterprise Library.

WCF Web API - Making REST a First-Class WCF Citizen(tugberkugurlu.com)

submitted by dpeterson(3464) 2 months, 19 days ago

Applications are continually evolving to expose their functionality over the web for example social services like Flickr, Twitter and Facebook. Aside from social applications, organizations are also looking to surface their core enterprise business functionality to an ever expanding array of client platforms. WCF Web API allows developers to expose their applications, data and services to the web directly over HTTP. This allows developers to fully harness the richness of the HTTP as an application layer protocol. Applications can communicate with a very broad set of clients whether they be browsers, mobile devices, desktop applications or other backend services. They can also take advantage of the caching and proxy infrastructure of the web through providing proper control and entity headers. We are designing specifically to support applications built with a RESTful architecture style though it does not force developers to use REST. The benefits of REST for your applications include discoverability, evolvability and scalability. read more...
