dynamic d = new
{
    id = "DOC1800243243470"
};

Document doc = await client.CreateDocumentAsync(collectionSelfLink, d);

//Upsert an Attachment which links to binary content stored somewhere else
//Use the MediaLink property of Attachment to set where the binary resides
//MediaLink can also point at another Attachment within Azure Cosmos DB.
Attachment a = await client.UpsertAttachmentAsync(doc.SelfLink, new Attachment { Id = "foo", ContentType = "text/plain", MediaLink = "link to your media" });
