It could be a bit of a pain to try to use Images as buttons, for those scenarios when you needed to display a certain image but also needed the user to be able to click on it, with all that that implies. A nice animation, perhaps change of color, and of course the triggering of an event or the ability to bind a Command. As of Xamarin Forms 3.4, this is no longer a pain, now you can define an ImageButton like you would define any element in the interface, and use it similarly to how you would use an Image, and make it respond to how a Button would.
Mastering the StackLayout will make your UIs look so much better, and it is quite simple. Here is how.
Let’s imagine that you already have some login functionality in place inside your application so we can focus on the task at hand: implementing biometrics inside the iOS application. Basically either TouchID or FaceID, depending on what is supported by the device (iPhone 5s to iPhone 8 support TouchID and iPhone X, XR, XS and XS Max support FaceID).
Deploying your app to an iOS device can be tricky at times. But later versions of Visual Studio make it a breeze, here is how to do it.
Well, the title sums it up doesn’t it? If you are going to use Xamarin Forms, WPF, or Windows, you need to know what XAML is.
Getting started building your Xamarin apps? This is the template to use when using Windows.

HOW!? How does Xamarin achieve this? Are you lying to me? This isn’t true right? Is it?
Why would it be important to you to learn Xamarin? Here I discuss the benefits and what you can obtain from this tool.
A brief look at what is Xamarin so you get a sense of what it will help you with and how it will achieve that.
An introduction to the free course here or on YouTube to learn the basics of Xamarin.Forms development
The Xamarin Forms previewer is a great tool that helps you see in real time how your Xamarin apps' interface is going to look like in a real device. But it seems that Microsoft decided in Visual Studio 2017 15.8 to get rid of it, it isn't anywhere to be found! Is it?
What the content moderator service does is, as its name may suggest, provide you information that will help you automate moderation decisions. For example, you may want to hide images that are sexually explicit, or that contain some sort of adult content. In the example that we will be working with we will be hiding profanity (curse words) from a "tweet" (you know, for our imaginary Twitter for Kids app).
As I was working with a ListView in Xamarin Forms I came across a couple of issues, here I explain how I solve some custom renders not being correctly displayed inside a ViewCell, and the NumberOfRowsInSection method throwing an exception when HasUnevenRows is set to true.
This video covers the way in which you can easily insert elements into an SQLite database on a Windows Presentation Foundation project.
And as I stated at the beginning of the video, this is part of my 18-hour WPF Masterclass course that I have on Udemy, which you can get for only $9.99 here: https://www.udemy.com/windows-presentation-foundation-masterclass/?couponCode=EDUARDO
In this video, I talk about how you can create a custom renderer to customize the looks of a Progress Bar for your iOS applications built with Xamarin Forms. That includes changing the progress tint color (foreground color) and the height.
A video about the usage of one of the Microsoft Cognitive Services (Text Analytics API) to identify the language of a text, and implementing this functionality on a WPF application.
