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:
internal class Program
{
private static void Main(string[] args)
{
CreateSaveAndGet().Wait();
//CleanUp().Wait();
}
public static async Task CreateSaveAndGet()
{
//connect database
var client = GetClient();
//find or create a database
var database = await GetDatabase(client);
//create a collection
var collection = await GetCollection(client, database);
Console.WriteLine("Save new flashcards...");
var flashcard1 = await client.CreateDocumentAsync(collection.SelfLink, new FlashCard()
{
ID = "1",

});
var flashcard2 = await client.CreateDocumentAsync(collection.SelfLink, new FlashCard()
{

Answer = "@DocumentDB",
});
var flashcards = await Task.Run(() => client.CreateDocumentQuery(collection.DocumentsLink)
.AsEnumerable()
.ToList());
Console.WriteLine("Iterating through flashcards...");
foreach (var flashcard in flashcards)
{
Console.WriteLine("QUESTION " + flashcard.ID.ToString() + ": " + flashcard.Question);
Console.WriteLine("Answer: " + flashcard.Answer);
Console.WriteLine("Press a key");
Console.ReadKey();
}
Console.ReadKey();

Console.ReadKey();

Console.ReadKey();
}
private static async Task CleanUp()
{
//connect database
var client = GetClient();
//find or create a database
var database = await GetDatabase(client);
//create a collection
var collection = await GetCollection(client, database);
await client.DeleteDocumentCollectionAsync(collection.SelfLink);
}
private static DocumentClient GetClient()
{
string endpoint = ConfigurationManager.AppSettings["EndPoint"];
string authKey = ConfigurationManager.AppSettings["AuthKey"];
Uri endpointUri = new Uri(endpoint);
var client = new DocumentClient(endpointUri, authKey);

}
private static async Task GetDatabase(DocumentClient client)

if (databases.Any())

}
else
{

}
return database;
}
private static async Task GetCollection(DocumentClient client, Database database)
{
var collectionName = "flashcards";
