Step 1:

Create and Host the WCF Service.

a. Create the Contract. This got only one method, which is taking as input a file to upload.

IService1.svc

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.Text;
 namespace FileUploadService      
{
        [ServiceContract]
    public interface IService1                         {

 

        [OperationContract]
        void SaveFile(UploadFile UploadFile);
}
}

b. Create the Data Contract. This is going to contain the information about the uploaded file. You could either put this UploadFile Data Contract in same file with contract or in separate file.

[DataContract]
    public class UploadFile    {
        [DataMember]
        public string FileName;

        [DataMember]
        public byte[] File;
    }

c. Implement the Service. We are simply creating instance of FileStream in create mode and writing the stream into that.
