Recently I decided that I wanted to see how easy it would be to build a Windows 8 application that consumed the Windows Azure Management API. It seemed like it should be an easy thing, and something that could potentially end up in a nice management/overview/dashboard kind of application. However, it isn’t quite that simple as I thought as Windows Azure uses certificates for authentication of the HTTP requests being used.
Using certificates for HTTP requests isn’t really that hard, at least not when working in .NET. But in Windows 8 apps, we are using WinRT, which is way more sandboxed, and to be honest, a bit more complicated, which makes it a little bit more complex…

As a follow up to my previous post about encrypting messages for the Service Bus, I thought I would re-use the concepts but instead of encrypting the messages I would compress them.
As the Service bus has limitations on how big messages are allowed to be, compressing the message body is actually something that can be really helpful. Not that I think sending massive messages is the best thing in all cases, the 256kb limit can be a little low some times.
Anyhow… The basic idea is exactly the same as last time, no news there…but to be honest, I think this type of compressions should be there by default, or at least be available as a feature of BrokeredMessage by default… However, as it isn’t I will just make do with extension methods…

A week ago I ran into Alan Smith at the Stockholm Cental Station on the way to the Scandinavian Developer Conference. We were both doing talks about Windows Azure, and we started talking about different Windows Azure features and thoughts. At some point, Alan mentioned that he had heard a few people say that they would like to have their BrokeredMessages encrypted. For some reason this stuck with me, and I decided to give it a try…
My first thought was to enherit the BrokeredMessage class, and introduce encryption like that. Basically pass in an encryption startegy in the constructor, and handle all encryption and decryption inside this subclass. However, about 2 seconds in to my attempt, I realized that the BrokeredMessage class was sealed. An annoying, but somewhat understandable decision made by Microsoft. Ok, so I couldn’t inherit the class, what can you do then? Well, there is no way to stop me from creating a couple of extension methods…
