400 error when calling web service

1) First i created the web app with the service reference of the created web service suppose Barcode39 is. Quick way is Goto project properties of your WCF Service Project in Visual studio, open Web tab/ page and make sure IIS web server is selected and IIS Express not selected mention your web address like. There are two problems I can see in your code. First, the name attribute of the < service> element in web. config is only listing " serviceName" - if this is not the fully - qualified name of the service class, it won' t be used. Second, you shouldn' t use. Try to do the following: 1. Add a new Service Reference named wsZipeee pointing to the Web Service 2. From the Calling location ( another Web App, Winform, et al) : Dim ws as New wsZipeee. ZipeeeSoapClient( ) Dim. Just form your data ( using Json. Net) as: var obj = new { States = new[ ] { new{ State = " MX" } }, Zip = " ", Miles = " ", PaginationStart = 1, PaginationLimit = 3 } ; string data = JsonConvert.
