Consuming an ASMX Web Service from a WCF client

As a unified distributed communication platform, WCF can help developers build standard SOAP XML-based Web Services so that traditional XML Web Service clients can consume it. Likewise, it is also quite convenient to use WCF-based client applications for consuming traditional XML Web Services.

In this recipe, we will show you how to consume a traditional ASMX Web Service from a WCF-based client application.

How to do it...

We will use a simple ASMX Web Service as an example here. The complete steps for consuming the sample service are as follows:

1. Create the sample ASMX Web Service.

   The sample ASMX Web Service contains a single operation that returns some string data. The complete definition of the Web Service is shown in the following code snippet.

   [WebService(Namespace = "http://tempuri.org/")]
   [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
   public class TestWebService : System.Web.Services.WebService
   {
   
      [WebMethod]
      public...
