Xamarin Workbooks (Quick Intro)
David Silverlight will be showing how we can use Xamarin Workbooks to help us organize our favorite bits of code, tips, tricks and techniques that we frequently use in our daily lives as developers. For this topic, David will give us a quick overview of this useful tool and show us how it can help us to better organize our ever growing mountain of knowledge as well as provide ways for us to learn new techniques as well as share information.
Making your Mobile App Serverless with Azure Functions (Main Presentation)
Azure Functions is an event driven, compute-on-demand experience that extends the existing Azure application platform with capabilities to implement code triggered by events occurring in Azure or third party service as well as on-premises systems. Developers can leverage Azure Functions to build HTTP-based API endpoints accessible by a wide range of applications, mobile and oT devices.
In this session we will give you an overview of Azure Functions and walk you through some real world examples of how Azure Functions were used in Mobile Apps to either replace or extend functionality. This will include live coding demonstrations as well.
Joe Raio is a Microsoft Technical Evangelist based in Miami, Florida. As a technical evangelist, Joe primarily focuses on presentations leveraging Microsoft Azure focused on website development and cloud technology. Prior to becoming an evangelist for Microsoft, Joe successfully owned and operated three small businesses centered around website development and marketing.

Costa Farms is a family-owned group of companies headquartered in beautiful Miami, Florida that grow houseplants such as the canela tree, orchids, and Cecilia Aglaonema.
Learn how Joe Raio and his colleagues at Microsoft helped Costa implement a smart IoT solution to allow them to monitor important vital statistics of their nurseries in real time. The solution included using Arduino Devices, Azure IoT Hub, Azure Functions and more.
In this session we will walk through each piece of the puzzle. In addition, we will demonstrate how this same solution can be easily modified and applied to many different scenarios, not just farming.
I participate in a lot of hackathons. Whether its an internal up-skilling event, university hackathon, or on site with a partner. These are often some of the most fun and frustrating things I get to work on.
At just about every hackathon, we use GitHub to setup a central repo with all the parts of the project we are working on. This could for example contain a web app, azure functions, Xamarin app, console app etc. We normally will just throw everything into its own folder and work from the one repo to keep it easy for everyone.
Often, I want to deploy my web app (and only the web app) right from this repo as I am pushing changes to GitHub. Thankfully through Azure, not only is it very easy to setup continuous deployment using GitHub, but you can also specific what folder within the repo to deploy from.
To deploy an ASP.NET Core web app to Azure from a specific folder in your repository, you simply have to add a new application setting called ‘project’ and point it to the source folder of the project.
For example; I have a project consisting of a UWP slideshow application and my web app to manage the slides. The repository can be found here: https://github.com/joescars/MICMediaSlideshow
In this instance, I only want to deploy the folder ‘MicMediaManager’ to my web app. To do this I connected my Azure Web App to GitHub for continuous deployment and then added the following settings to my app settings.
That’s it! Now I can update each folder independently and my web app will only publish changes within the source folder specified.
So… what about Azure Functions?
This same method works with Azure Functions as well. I’ve setup a sample repository here: https://github.com/joescars/AzureFunctionsCustomDeployment in which I have a folder with my Functions inside their own sub-folder. I then go to the function app settings, add a project setting and it will deploy all my Functions from that folder.
Late last year I had the opportunity to work with Costa Farms on a small proof of concept project. The goal was simple; actively monitor pH levels in their plants water supply and take intelligent action if needed.
We were able to accomplish this using Azure IoT Hub, Stream Analytics, Event Hubs and Azure Functions.
