Simple.OData.Client in .Net - c#-4.0

Question

I am working with an application that will call OData Service. I tried the Simple.OData.Client but I can't get it working..
Here is the code that I try
var client = new ODataClient("http://packages.nuget.org/v1/FeedService.svc/");
var packages = await client.FindEntriesAsync("Packages?$filter=Title eq 'Simple.OData.Client'");
foreach (var package in packages)
{
Console.WriteLine(package["Title"]);
}
I get this error
Error 1 The 'await' operator can only be used within an async method. Consider marking this method with the 'async' modifier and changing its return type to 'Task'.

using System;
using Simple.OData.Client;
namespace ODataClient
{
class Program
{
static void Main(string[] args)
{
new Manager().GetData();
Console.ReadLine();
}
}
}
using System;
using System.Collections.Generic;
using System.Threading.Tasks;
namespace ODataClient
{
public class Manager
{
private readonly Simple.OData.Client.ODataClient client;
public Manager()
{
client = new Simple.OData.Client.ODataClient("http://packages.nuget.org/v1/FeedService.svc/");
}
public void GetData()
{
try
{
IEnumerable<IDictionary<string, object>> response = GetPackages().Result;
foreach (var package in response)
{
Console.WriteLine(package["Title"]);
}
}
catch (Exception e)
{
Console.WriteLine(e);
}
}
private async Task<IEnumerable<IDictionary<string, object>>> GetPackages()
{
var packages = await client.FindEntriesAsync("Packages?$filter=Title eq 'Simple.OData.Client'");
return packages;
}
}
}

This is even simpler. We need SimpleQuery method, since we cannot add the async keyword to the Main or any entry point methods.
static async void SimpleQuery()
{
var client = new ODataClient("http://blahb...lah.svc/");
try
{
var packages = await client.FindEntriesAsync("Products");
foreach (var package in packages)
{
Console.WriteLine(package);
}
} catch (Exception e)
{
Console.WriteLine("Simple Query " + e);
}
}
static void Main(string[] args)
{
Console.WriteLine("Press Enter when the job is completed");
SimpleQuery();
Console.ReadLine();
}
