WCF REST 400 Bad Request

Today while I was writing my WCF Rest Client, I was getting error as "400 Bad Request". Finally I realized the culprit of error was service name in web.config file. In order to resolve this error, make sure service name is matching with your service markup's service name.

If you have servicename1.svc, right click on that file and select "View MarkUp". Copy Service value from that and paste it into webconfig's services service name.

Service1.svc MarkUp:

<%@ ServiceHost Language="C#" Debug="true" Service="MyServiceNameSpace.Service1" CodeBehind="Service1.svc.cs" %>

Web.config Services Section:
<services>

   <service name="MyServiceNameSpace.Service1">

     <endpoint address="" behaviorConfiguration="restService"

           contract="MyServiceNameSpace.IService1" binding="webHttpBinding"/>

     <endpoint address="mex" contract="MyServiceNameSpace.IService1"  binding="mexHttpBinding" />

   </service>

</services>

Working Rest Configuration:
