Running unit tests when deploying to Windows Azure Web Sites
When deploying an application to Windows Azure Web Sites, a number of deployment steps are executed. For .NET projects, msbuild is triggered. For node.js applications, a list of dependencies is restored. For PHP applications, files are copied from source control to the actual web root which is served publicly. Wouldn’t it be cool if Windows Azure Web Sites refused to deploy fresh source code whenever unit tests fail? In this post, I’ll show you how. Disclaimer: I’m using PHP and PHPUnit here but the same approach can be used for node.js. .NET is a bit harder since most test runners out there are not supported by the Windows Azure Web Sites sandbox. I’m confident however that in the near future this issue will be resolved and the same technique can be used for .NET applications.

Tales from the trenches: resizing a Windows Azure virtual disk the smooth way
We’ve all been there. Running a virtual machine on Windows Azure and all of a sudden you notice that a virtual disk is running full. Having no access to the hypervisor nor to its storage (directly), there’s no easy way out… Big disclaimer: use the provided code on your own risk! I’m not responsible if something breaks! The provided code is as-is without warranty! I have tested this on a couple of data disks without any problems. I've tested this on OS disks and this sometimes works, sometimes fails. Be warned. Download/contribute: on GitHub When searching for a solution to this issue,the typical solution you’ll find is the following:

Storing user uploads in Windows Azure blob storage
On one of the mailing lists I follow, an interesting question came up: “We want to write a VSTO plugin for Outlook which copies attachments to blob storage. What’s the best way to do this? What about security?”. Shortly thereafter, an answer came around: “That can be done directly from the client. And storage credentials can be encrypted for use in your VSTO plugin.” While that’s certainly a solution to the problem, it’s not the best. Let’s try and answer… The first solution that comes to mind is implementing the following flow: the client authenticates and uploads data to your service which then stores the upload on blob storage.

Protecting your ASP.NET Web API using OAuth2 and the Windows Azure Access Control Service
An article I wrote a while ago has been posted on DeveloperFusion: The world in which we live evolves at a vast speed. Today, many applications on the Internet expose an API which can be consumed by everyone using a web browser or a mobile application on their smartphone or tablet. How would you build your API if you want these apps to be a full-fledged front-end to your service without compromising security? In this article, I’ll dive into that. We’ll be using OAuth2 and the Windows Azure Access Control Service to secure our API yet provide access to all those apps out there.

Configuring IIS methods for ASP.NET Web API on Windows Azure Websites and elsewhere
That’s a pretty long title, I agree. When working on my implementation of RFC2324, also known as the HyperText Coffee Pot Control Protocol, I’ve been struggling with something that you will struggle with as well in your ASP.NET Web API’s: supporting additional HTTP methods like HEAD, PATCH or PROPFIND. ASP.NET Web API has no issue with those, but when hosting them on IIS you’ll find yourself in Yellow-screen-of-death heaven.

How I push GoogleAnalyticsTracker to NuGet
If you check my blog post Tracking API usage with Google Analytics, you’ll see that a small open-source component evolved from MyGet. This component, GoogleAnalyticsTracker, lives on GitHub and NuGet and has since evolved into something that supports Windows Phone and Windows RT as well. But let’s not focus on the open-source aspect. It’s funny how things evolve. GoogleAnalyticsTracker started as a small component inside MyGet, and since a couple of weeks it uses MyGet to publish itself to NuGet. Say what? In this blog post, I’ll elaborate a bit on the development tools used on this tiny component.

A phone call from the cloud: Windows Azure, SignalR & Twilio
Note: this blog post used to be an article for the Windows Azure Roadtrip website. Since that one no longer exists, I decided to post the articles on my blog as well. Find the source code for this post here: 05 ConfirmPhoneNumberDemo.zip (1.32 mb). It has been written earlier this year, some versions of packages used (like jQuery or SignalR) may be outdated in this post. Live with it.

Sending e-mail from Windows Azure
Note: this blog post used to be an article for the Windows Azure Roadtrip website. Since that one no longer exists, I decided to post the articles on my blog as well. Find the source code for this post here: 04 SendingEmailsFromTheCloud.zip (922.27 kb). When a user subscribes, you send him a thank-you e-mail. When his account expires, you send him a warning message containing a link to purchase a new subscription. When he places an order, you send him an order confirmation. I think you get the picture: a fairly common scenario in almost any application is sending out e-mails.

From API key to user with ASP.NET Web API
ASP.NET Web API is a great tool to build an API with. Or as my buddy Kristof Rennen (and the French) always say: “it makes you ‘api”. One of the things I like a lot is the fact that you can do very powerful things that you know and love from the ASP.NET MVC stack, like, for example, using filter attributes. Action filters, result filters and… authorization filters. Say you wanted to protect your API and make use of the controller’s User property to return user-specific information. You probably will add an [Authorize] attribute (to ensure the user is authenticated) to either the entire API controller or to one of its action methods, like this: Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/

What PartitionKey and RowKey are for in Windows Azure Table Storage
For the past few months, I’ve been coaching a “Microsoft Student Partner” (who has a great blog on Kinect for Windows by the way!) on Windows Azure. One of the questions he recently had was around PartitionKey and RowKey in Windows Azure Table Storage. What are these for? Do I have to specify them manually? Let’s explain… All Windows Azure storage abstractions (Blob, Table, Queue) are built upon the same stack (whitepaper here). While there’s much more to tell about it, the reason why it scales is because of its partitioning logic. Whenever you store something on Windows Azure storage, it is located on some partition in the system. Partitions are used for scale out in the system. Imagine that there’s only 3 physical machines that are used for storing data in Windows Azure storage:
