[dba-VB] FYI: Microsoft embracing REST, ATOM and JSON by Open Data Protocol (OData)

Hi All --

Even more dynamic oData web service test call:

using System;
using System.Linq;
using System.Data.Services.Client;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var proxy = (new DataServiceContext(new Uri(@"http://services.odata.org/Northwind/Northwind.svc/")).CreateQuery<dynamic>("Employees")); 

            var employees = from e in (proxy.ToList()) 
                            where e.Title.StartsWith("Sales") 
                            orderby e.LastName 
                            select e;

            employees.ToList().ForEach(e =>    
                Console.WriteLine("{0}. {1} {2} - {3}", e.EmployeeID, e.LastName, e.FirstName, e.Title));
        }
    }
}

Just musing around mainstream tendency outlined here:
