Presentation

I recently created a simple test / demo application using Windows Phone 7 to consume WCF services that host the console. It looks like there are tutorials / documentation on this topic on the internet.

All tutorials explain very well what and how to use a WCF service for the Windows Phone 7 platform. The standard method is that when using these WCF services, we need to create a “service reference” that refers to the WCF service. real. It could also be when hosting IIS or browsing wsdl i.e. the service can be found in the browser.

What about a console for a WCF service? Oh, it won’t work because we cannot add the type “service reference” directly, since we are not supposed to be able to access these services since they are simply not available. Then we can imagine that there is a way, similar to a Silverlight project, to consume an active service via ChannelFactory and create a proxy somehow, so I tried it or this result ‘ NotSupportException ‘throw awayIt is being worn. Ahh … again, persistent like any developer in the world, I think there must be a way, but I just don’t know how, so the search continues …

I scanned the internet from top to bottom, with no success. There is usually a document that says you can use the Clientbase and IChannel interface. should use. etc. But now that I no longer want to do all this dirty work, I focused on thinking and, of course, drank normal coffee.

So that I can with all the caffeine, if I can’t add a “service reference” to those services, then why not publish the “service reference” in a newly created WCF service. I’m sure I can start as well as well . “is simple, and when it comes to this newly created service that shows how an existing WCF service hosted in a console application works, break it!

To save the time of my fellow developers, I think I should share it and that’s it.

Context

System requirements: .NET Framework 4.0 from 2010 VS and Windows Phone 7 SDK.

Projects

1. ActualService
2. ActualServiceForPhone
3. IPerson
4. IPersonSL

< li> SLClient.Web

8. SLPhoneClient

Before explaining what each plan does, keep in mind that this important article is not about coding, but a trick or technique for connecting existing WCF services to the new Circulate service.

Ongoing Maintenance

It is often the service that contains the correct interface implementation for our person objects:

 public class Service1: IService1, IServicePolicy    ...

ActualServiceForPhone

This is a true Windows Phone 7 hyperlink service that calls the underlying WCF software “ ActualService “.

IPerson

The interface class is used in both the service and the client; H. This program is used for implementation at all service levels or as a typical customer standard.

[service contract]public interface IService1 …[Service contract (Name = “IDienst1”)]public interface iservice1async … [Data contract]public class man[Data Member] …

IPersonSL And IPersonSLPhone

The following two class libraries are similar to IPerson , according to the requirements, each design type requires its own library class, so a Silverlight project requires a Silverlight library class, Windows Phone 7, then you need a Library class type, and, hence the role of these two types. Please note that the zip file is an actual link to my Person.cs and not an exact copy as it saves a little on every update / maintenance. SL-silverlight, SLPhone-silverlight windows 7 phone

ServiceHost

 use (ServiceHost batch = new ServiceHost (typeof (Service1), new Uri [] new Uri ("http: // localhost: 60011", UriKind.Absolute)))    ...    host.Open ();    Console.ReadLine ();    host.Close ();    ...

SLClient And SLClient.Web

These two responsibilities are by default a template project for Silverlight 4.0 with SLClient , which contains only a specific button and grid to reflect our own WCF service data ActualService .

SLPhone Client

This is now a Windows Phone 7 Silverlight project. Choose a standard for creating Silverlight templating programs. This project also contains a separate button and combo box to display.Learn the facts about ActualServiceForPhone .

• Download the attached magic formula zip file.
• Start VS 2010 and open the solution file and all build projects.
• Run servicehost connected to the console with cmd administrator rights (run in administrator mode).
• Set ActualServiceForPhone to Start Project Forward and press F5 (remember to check the port number to make sure the service is running).
• To the floatable SLClient (silver Start Project button for this project and press F5).
• Similarly, to explore Windows Phone 7, select each SLPhoneClient as Start Project and press F5.
