WCF REST Webinvoke not found

Question

Following is the code i am using in my test app:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.ServiceModel.Description;
using System.IO;

namespace MyWCFServices
{
    [ServiceContract]
    interface IHelloWorldService
    {
        [OperationContract]
        String GetMessage(String name);

        //[OperationContract]
        //[WebInvoke(Method = "PUT",UriTemplate = "File/{fileName}")]
        //[WebContentType("application/octet-stream")]
        // bool UploadFile(string fileName, Stream fileContents); 
        [OperationContract]
        [WebInvoke(UriTemplate = "UploadFile/{fileName}")]
        void UploadFile(string fileName, Stream fileContent); 
    }
}

It gives and error on compilation for webinvoke. Any idea about the same ??

WebInvokeAttribute is in separate assembly System.ServiceModel.Web.dll. Did you reference that assembly? Also you must add using System.ServiceModel.Web;

Edit:

To use System.ServiceModel.Web.dll assembly you must use at least .NET 3.5 and you can't use .NET 4.0 Client Profile.

What version of .NET/WCF are you using? – Ladislav Mrnka Apr 25 '11 at 12:42
I am using .NET 4.0 (not 4.0 Client Profile) – Ankit Apr 25 '11 at 12:57
I have never heard about `WebContentType` attribute and as I know it is not part of WCF. – Ladislav Mrnka Apr 25 '11 at 13:06
What type of project are you using? – Ladislav Mrnka Apr 25 '11 at 13:06
@Ladislav : I'm facing the same issue. Also, I don't see reference to System.ServiceModel.Web in add reference dialog. I'm using Visual Studio 2010 (.net 4.0). Can you help me if i'm missing something ?? – Rohit Jan 25 '12 at 06:07
Hmmm...dont mind but what specific client profile are you asking? I'm new to web and working on creating a simple page in html5 and need to call a webservice. – Rohit Jan 25 '12 at 08:41
list of namespace added: using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.Text; – Rohit Jan 25 '12 at 08:46
Thanks ladislav i found a solution for this – Rohit Jan 25 '12 at 09:02
I am also facing same problem. i am using Visual Studio 2010 – Dawood Ahmed Feb 13 '13 at 13:08
somehow ReSharper isn't able to add the reference automatically – Higgs Jul 01 '15 at 17:17
@Rohit what was the solution? – Malcolm Salvador May 29 '17 at 03:42
