Hi,

I Have a problem with a wcf service.

I have a console aplication and I need to consume the service without using app.config, so I had to set the endoint, etc by code.

I do have a service reference to the svc, but I cant use the app.config.

Here's my code:

BasicHttpBinding binding = new BasicHttpBinding();
binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Ntlm;
EndpointAddress endpoint =
new EndpointAddress("http://localhost:XXXX/_vti_bin/Testingapp.svc/mex");
string internetList = "Interaktor - Henvendelser";
string internetSite = "http://localhost:20311  ";
string ggt = ww.DoWork();

At the last line when I do ww.DoWork(), I get the error:
Content Type text/xml; charset=utf-8 was not supported by service http://localhost:8731/WcfServicio/MiServicio. The client and service bindings may be mismatched.

Any suggestions??
