WCF Large SOAP Request Exception 400 Bad Request

Question

I am looking for solution to my WCF Error 400 Bad Request with SOAP request longer than 64K. I know there are a lot of solutions out there when I google it. However, I am still not successful in fixing my site to work. Hence, I am seeking for professional advice here.

Client Side Code:

Private Sub Calculate()
    Dim svc As New XXXService.XXXServiceClient

Answer 1

I have found the issue myself:

1. Binding between server side and client side must be the same, hence I change both to basicHttpBinding
2. Service name is case sensitive, I changed "WcfClient.XXXService" to "wcfClient.XXXService" and it works now.

Hope this can help others with the same difficulties =)
