Swing back to your familyvaultdocs bucket in AWS and click on the refresh icon next to the EU (Frankfurt) region. You will see the folder MinecraftPictures you specified in code.
Clicking on the folder, you will see the contents listed. I previously uploaded the SquidNugget.png image, but the StampyCat.png image we uploaded in our code sample has been prefixed with the date as specified in code.
The code is run and the files are added almost immediately. Admittedly they aren't very big files, but this goes to show how easy it is to add a simple storage service to AWS and integrate that with a .NET application.
