Thanks for the help Miguel. &nbsp;Deleting the entire servicemodel section allowed the new reference to be created and the error to be found.

Hello.<br />

When trying to add a service reference I receive the following error:<br />

C# MVC project, adding a service reference E_INVALIDARG

Microsoft’s ASP.NET MVC is a web application framework that implements the model–view–controller (MVC) pattern. As an open-source software, it’s set apart from the ASP.NET Web Forms component, which is proprietary.

.NET MVC

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

Windows Communication Foundation (WCF) is a tool used to implement and deploy a service-oriented architecture (SOA) to support distributed computing where services have remote consumers. It features a runtime and a set of APIs in the .NET Framework for building connected, service-oriented applications. Services typically have a WSDL interface (Web Services Description Language) that any WCF client can use to consume the service, regardless of which platform the service is hosted on. WCF implements many advanced Web services (WS) standards such as WS-Addressing, WS-ReliableMessaging, WS-Security, RSS Syndication Services, WS-Discovery, routing and better support for REST services.

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
