Azure Cloud Storage for Everyone!
You can use Windows Azure Blob Storage even if you are not running applications in Azure. You can host html web pages, content, customer files, application deployments (such as ClickOnce), etc. I will show the basics of accessing blob storage through the storage client library APIs -- uploading blobs, downloading blobs, iterating through directories to see the blobs listed, what assemblies you need to add to your application, etc. All of these APIs can be called with REST as well.
