Return Raw JSON in WCF: Simplified Guide

If you're working with WCF services, you may find yourself needing to return raw JSON data. This can be easily achieved by modifying the configuration of your service.

  1. Step 1: Configure your service to use webHttpBinding
  2. Step 2: Add a method to your service that returns JSON

Step 1: Configure your service to use webHttpBinding

In order to return raw JSON, you'll need to configure your service to use the webHttpBinding. You can do this by adding the following code to your app.config file:

<system.serviceModel>
  <services>
    <service name="YourServiceName">
      <endpoint address="" binding="webHttpBinding" contract="YourContractName" behaviorConfiguration="web">
      </endpoint>
    </service>
  </services>
  <behaviors>
    <endpointBehaviors>
      <behavior name="web">
        <webHttp/>
      </behavior>
    </endpointBehaviors>
  </behaviors>
</system.serviceModel>

Note that you'll need to replace "YourServiceName" and "YourContractName" with the appropriate values for your service.

Step 2: Add a method to your service that returns JSON

Now that your service is configured to use webHttpBinding, you can add a method that returns raw JSON data. Here's an example:

[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json)]
public string GetRawJson()
{
return "{"name"":""John Smith""
