Step 1: Run the PowerShell Scripts
Step 2: Use the new Azure portal at portal.azure.com
Step 3: Run NuGet: Install-Package Microsoft.Azure.Documents.Client -Pre
Step 4: This is the Flashcard class
public class FlashCard
{
[JsonProperty(PropertyName = "id")]
public string ID { get; set; }
[JsonProperty(PropertyName = "question")]
public string Question { get; set; }
[JsonProperty(PropertyName = "answer")]
public string Answer { get; set; }
}
Step 5: This is the console application:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Azure.Documents;
using Microsoft.Azure.Documents.Client;
using Microsoft.Azure.Documents.Linq;
using System.Configuration;
