Create a WCF service to communicate with JQuery through JSON

Question

Hi,

I have a bog standard html page. All I want to do is :

• use JQuery on that page to send JSON requests to a WCF service
• retrieve JSON back.

That's it.

I have the html page and JQuery written, no problem.

---

However, I can't find one tutorial that works. All the ones I've found have many conflicting parts to do with behaviors, editing the svc file with a Factory attribute, etc.

Can someone please point me to a bog standard tutorial / example that ACTUALLY works?

Thanks.

Answer 1

Rick Strahl has a pretty good resource for this:

• Query AJAX call to a WCF REST Service

More importantly, he has a full sample project he uses in his DevConnection talks here:

• Updated jQuery and WCF 3.5 JSON Samples posted

I always find using a full blown project I can fire up in Visual Studio is a much better resource than any walk through... hopefully the same is true for you.

I have finally been able to get this to work using WCF 4.0

USING windows comunication foundataion WCF 4.0 (.net 4.0)

I have wasted a lot of my time....so I wanted to share my knowledge on how to do this.

Another quick creation of WCF service is using *.svc like
<%@ServiceHost language=c# Service="Microsoft.Samples.MyWCFService" Factory="System.ServiceModel.Activation.MyWebServiceHostFactory" %>

This does not require you to have any configuration in your web.config file and this Factory automatically instantiates your service and as this service runs under the same web-app process thread, it shares the Session with your asp web-application.
