以编程方式创建WCF客户端

我有一个启用了Silverlight的WCF服务的网站。该服务工作正常,我可以在浏览器中浏览到WSDL页面,没有问题。

现在,我正试图在一个DLL中创建一个客户机。不过,我需要以编程方式创建整个客户机,因为它是在一个DLL中被调用的,不管出于什么原因(通过设计?)不会从自己的配置文件中读取ServiceModel节。

我的代码是:

Dim endp As EndpointAddress = New EndpointAddress("http://www.mydomain.com/licensing/lic.svc")
Dim bind As WSHttpBinding = New WSHttpBinding()
Dim svc = New lnt.licClient(bind, endp)
Dim rsp = svc.CheckIt(key)

但当我调用svc.checkit方法时,我得到以下错误:

Content Type application/soap+xml; charset=utf-8 was not supported by service http://www.mydomain.com/licensing/lic.svc. 
The client and service bindings may be mismatched.
{"The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'application/soap+msbin1'.."}

我如何正确地创建我的客户机,使它们正确地“匹配”??
事先谢谢!!!!
