Recap from #Braindump at the HUB

Yesterday I attended #braindump at the Hub, to discuss Windows Azure, Win8, WinPhone and Xamarin development. With a focus on app development and getting local developers to publish (on any Appstore). The event had very good speakers and a diverse set of characters in the audience. I wish more people has attended but for me it was a great kickoff to a new project.
A nice surprise was meeting Chris Risner (@chrisrisner) who’s content I have been following for quite sometime. We had a chance to talk about mobile services and some of the challenges in marketing and exposing WAMS to other developers.
I also had the chance to chat with Jeremy Foster (@codefoster) on the pros/cons of XAML vs. WinJS for Win8 Development. He shared a very nice gallery of examples called CodeShow. I think this was the turning point for the current project and the move to WinJS. I’m glad I was able to attend his session 🙂
I was happy to see the guys from Xamarin show off some of the new embedded solutions and (repeatedly) answer the questions from the crowd on how to “develop iOS and android apps from inside Visual Studio”. I gotta give it to (@bryancostanich) for his patience with the crowd and hope to see some more awesome tools in the future.
Lastly I met Matt Harris Co-Founder of SendWithUS one of the few partners of the SendGrid team. His session was very personal, he evangelized on what had started as a personal quest for better email management and ended up being a company. It is hard to believe this is the outcome from 11 months of work from a 7 person team. I liked his product but more so his passion, it is hard to find people with that determination.
Abe’s Insight: I’m still in awe with some of the gaps in knowledge from the technical audiences I interact with. The fragmentation in platforms has been there from the beginning (this is not news). We have been developing iOS apps, Android apps and lately Win8 and WinPhone separately; the search for that “one IDE to rule them all” should be over by now…seriously. It is all a business driven decision, going the HTML5 route vs the Native one is not a matter of user base and numbers but one of product development and how an app should be an extension of your company/product/business.

“Mobilize” your existing SQL Azure tables (from WASD to ZUMO)

I have been playing around with Windows Azure Mobile Services (ZUMO) and found a great article on Using an existing Azure SQL table with Windows Azure Mobile Services by Jeff Sanders. I have been trying to do the same but found some challenges along the way.

If you are using EF Data Migrations on you project you will need to ensure the schema is set to the name of the Mobile Service name instead of dbo (this might be tricky for some); or use the EF DB First Model approach. In addition to that you will need to make sure the column types being used by your app are compatible with the types for ZUMO. Lastly remember to set the id (Not ID as it is case sensitive) column to be an identity column.

With those small changes you will be able to access your previously created tables via ZUMO while minimizing impact to any legacy webapp you may have developed earlier.

Hope this helps 🙂

Do you or do you not know about the VERB… Cause everybody’s heard that the VERB is the word

Like Peter Griffin said the bird is the word, I say the VERB is the word. What I’m I talking about? HTTP Verbs.

I have been recently playing with Windows Azure Mobile Services commonly called ZUMO. In doing so I ran into a bit of a snag. I was trying to do CRUD operations from an MVC 4 app when i kept getting an error on updates. As many people know the typical mapping for REST APIs is something like this:

Update: HTTP PUT

While I had no issues inserting or reading the update action was failing with the following error “{“MethodNotAllowed“}. After some digging I was able to spot the issue. The ZUMO REST API is expecting the PATCH Verb instead of PUT.

I replaced the following:

var request = new HttpRequestMessage(HttpMethod.Post, BaseAddress);


HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Add("X-ZUMO-APPLICATION", ApplicationKey);
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var request = new HttpRequestMessage(new HttpMethod("PATCH"), BaseAddress +;

That little tweak did the trick!

Hope this helps others playing with Windows Azure Mobile Services too. If you haven’t go ahead and give it a try 🙂

Global Windows Azure Bootcamp

Today I was able to demo some of the features of Windows Azure Mobile Services for the Global Windows Azure Bootcamp. We certainly had a great time.

Here is a video to recap some of the areas we covered:
