Adding ApiController to MVC project

Question

When i try to add ApiController to existing MVC project, it gives me the following error:

Error CS0234 The type or namespace name 'Http' does not exist in the namespace 'System.Web'

I updated and make sure that System.Net.Http referance is exist.

What is the couse?

The only code for this issue is the following and the error syntax i gave above.

public class ValuesController : System.Web.Http.ApiController
{
[HttpGet]
public IEnumerable<string> Values()
{
    return new string[] { "value1", "value2" };
}

}

You are confusing System.Web.Http and System.Net.Http, at least in the question. It should be System.Web.Http. You need to add a reference to the System.Web.Http Assembly (in Visual Studio: Solution Explorer -> your project -> References -> Add Reference) — Peter B

System.Web.Http is different to System.Net.Http

Add the reference to System.Web.Http and then
And then using System.Web.Http;
