CS0234: The type or namespace name 'Soap' does not exist in the namespace 'System.Runtime.Serialization.Formatters'

Question

I am using .NET 4.5 Visual Studio 2012 web application . It gives me runtime error as

CS0234: The type or namespace name 'Soap' does not exist in the namespace 'System.Runtime.Serialization.Formatters'

But I added the reference already to System.Runtime.Serialization.Formatters.Soap;

And also in the Class file as;

using System.Runtime.Serialization.Formatters.Soap;

Answer 1

A reference needs to be added from the framework. Just check and add this:

System.Runtime.Serialization.Formatters.Soap

Answer 2

go to Solution Explorer, Right click on Reference, Then select 1st option ie Add Reference. select assemblies and search SOAP in search bar. select library and press ok. error will get solved
