Create JSON documents (.NET)

A document can be created by using the CreateDocumentAsync method of the DocumentClient class. Documents are user defined (arbitrary) JSON content.

async Task CreateFamilyDocumentIfNotExists(DocumentClient client, string databaseName, string collectionName, Family family)
{
    try
    {
        await client.ReadDocumentAsync(UriFactory.CreateDocumentUri(databaseName, collectionName, family.Id));
    }
    catch (DocumentClientException e)
    {
        if (e.StatusCode == HttpStatusCode.NotFound)
        {
            await client.CreateDocumentAsync(UriFactory.CreateDocumentCollectionUri(databaseName, collectionName), family);
        }
        else
        {
            // Rethrow
            throw;
        }
    }
}

    public Address Address { get; set; }
    public bool IsRegistered { get; set; }
    public override string ToString()
    {
        return JsonConvert.SerializeObject(this);
    }
}

public class Parent
{
    public string FamilyName { get; set; }
    public string FirstName { get; set; }
}

public class Child
{
    public string FamilyName { get; set; }
