Question

I’m just wondering how to invoke WCF service through browser (Firefox)?

My WCF service look like this:

http://localhost:4249/TestService.svc

I’ve tried this:

[ServiceContract]
public interface ITestService
{
    [OperationContract]
    [WebGet(UriTemplate = "/GetAllPersons", ResponseFormat = WebMessageFormat.Xml)]
    List<Person> GetAllPersons();


public class TestService : ITestService
{
    public List<Person> GetAllPersons()
    {
        return Employees.CreateEmployees();
    }

And I’ve tried this in browser’s address line:

http://localhost:4249/TestService/GetAllPersons

But, I’ve got the following error:

Server Error in ‘/’ Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is
temporarily unavailable. Please review the following URL and make
sure that it is spelled correctly.

Requested URL: /TestService/GetAllPersons

What I did wrong?

Here’s my web.config file and you can take a look at:

Answer 1

In addition to the factory changes mentioned in the comment above, you need to enable webHttpBinding in your web.config. Use this as a template, copying the contract and name details from your existing web.config:

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"  multipleSiteBindingsEnabled="true" />
<bindings>
  <webHttpBinding>
    <binding name="WHB" crossDomainScriptAccessEnabled="true">
      <security mode="None" />
    </binding>
  </webHttpBinding>
</bindings>
<behaviors>
  <serviceBehaviors>
    <behavior name="AllowGet">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<services>
  <service behaviorConfiguration="AllowGet" name="">
    <endpoint address="" binding="webHttpBinding"
      bindingConfiguration="WHB" contract="" />
  </service>
</services>
