I have .net web app with entity framework and wcf(call services and have add/update stored procedure calls). Recently, I just change the datatype from int to string for the requirements.<br />

Update wcf debug no codes issues.<br />
Update edmx so the datatype is matching from object to database table column datatype.<br />

I have .net web app with entity framework and wcf(call services and have add/update stored procedure calls). Recently, I just change the datatype from int to string for the requirements.

Update wcf debug no codes issues.
Update edmx so the datatype is matching from object to database table column datatype.

Now it still have an error about datatype. and it points to service folder/reference.cs. the reference.cs look right to me. the datatype is updated. and now I don't know how to fix. Any issues?

wcf and entity framework

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.

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

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).
