If you are new to Xamarin.Forms (and I’m assuming you are) then there is a lot to learn, but none of it is very difficult… ok some of it is, but not until you’re into very advanced topics. The one thing you do need to know is C#. You don’t have to be an expert, but you do have to be comfortable with the language.
Here’s a problem I come across more often than I would have expected. I want my buttons to use Commands in the View Model, but in response to the command, I have to interact with the user in a way that is much easier to do in the code behind.
Let’s take the example of a user pressing a button to delete a record. The button calls a command in the ViewModel, but I want to show a confirmation dialog box in the view. If the user affirms the deletion, I want to do the work back in the View Model. Oy.

At the core of effective application development is a thorough knowledge of Visual Studio Mac. In this course, Visual Studio for Mac, you will learn how to work with VS Mac to produce enterprise-quality software.
First, you will explore the IDE by taking an extensive tour. Next, you will learn how Visual Studio Mac supports source control; specifically Git. Finally, you will discover how Visual Studio Mac supports Azure. When you are finished with this course, you will have a foundational knowledge of this integrated development environment that will help you as you move forward to creating software.
In my previous posts I showed how to get started with App Center and how to build an app on App Center. In this post, I will demonstrate how to distribute your shiny new app to your alpha or beta testers.
Return to App Center and confirm that your application has been built with the latest check in. Next, create your distribution group.
Create A Distribution Group
To do so, click on Distribute Groups, where you will see a button in the upper right hand corner: New Group.
Create and name your group (e.g., Alpha Testers) . You can allow public access , but then device registration won’t work (at least for now). Leave this off, and enter email addresses into the box labeled Who would you like to invite to this group?
In my previous (and first) blog post on App Center I talked about getting started, adding the SDK to your code, and looking at Analytics and Crash reporting. In this post I’d like to discuss building your app on App Center; which allows you to distribute your app to Beta testers and others.
There are a few steps in setting up and configuring your build process, but once done, building is as simple as pressing a button (or, even simpler, you can set it up to build on every push to your source control!)
There is no doubt that Microsoft’s VS App Center is an incredible resource for mobile application programmers. The problem is that it seems hard to get started. The good news is that once you get started, it turns out to be wicked easy!
For this blog post, I’m going to assume that you are already sold that App Center is the Cat’s Meow; if not check out this article by Microsoft on why App Center is so cool.
The short version is that App Center allows you to Build your application in the cloud, directly from your repository. You can Test (using Xamarin Cloud) and you can Distribute to beta testers. You can also set up and view analytics and crash reports. Finally, you can set up push notifications.
In the next few blog posts I’ll go over each of these areas, and be sure to keep an eye out for my forthcoming course on App Center on LinkedIn Learning (part of my Azure Essentials series) . You’ll find these posts on Wintellect’s blog and on my own.
Shawn Wildermuth has been tinkering with computers and software since he got a Vic-20 back in the early ‘80s.
As a Microsoft MVP since 2003, he’s also involved with Microsoft as an ASP.NET Insider and ClientDev Insider. You may have taken one of his more than twenty courses on Pluralsight
He’s authored eight books and innumerable articles on software development. You can also see him at one of the local and international conferences he’s spoken at including TechEd, Oredev, SDC, NDC, VSLive, DevIntersection, MIX, Devteach, DevConnections and Dev Reach.
He is one of the Wilder Minds. You can reach him at his blog. He’s also making his first, feature-length, documentary about software developers today called “Hello World: The Film”. You can see more about it here.
