The built-in TextBox control in UWP supports any textual input from the user, but in some cases, you might prefer to allow only plain numbers. In this article, I will show two different approaches which will allow you to do just that. Preventing non-digit input If we want to make sure no non-digit character can
The singleton pattern is useful when writing game components like a game manager or localization manager in Unity. I would like to share with you the implementation I am currently using in my project.
Can you count how many times you wrote something like: Or if you fancy LINQ (and can sacrifice a bit of performance)? If your answer is infinite or more, then check out the new way available in .NET Core 2.0 and newer: Array.Fill brings the best of both worlds – it is more succinct than
Today I was trying to implement reading of ushort values from a little-endian byte array. The code to retrieve a single value was pretty simple – shift the second byte by 8 to the left and add the first byte: What could possibly go wrong? It turned out quite a bit. The code was giving

However, as data binding uses reflection by default, it can have a negative impact on performance. Luckily, Xamarin.Forms support Compiled Bindings, which are akin to UWP’s x:Bind and
The Windows 10 Insider Preview build 18282 for the first time revealed a beautiful light theme of the Windows Shell (Start menu, Taskbar and Action Center). Many stock apps have already been updated to support this color scheme so in this article, we will check out how to add support for light theme task bar
String interpolation syntax introduced in C# 6 provides a convenient and readable alternative to string.Format.

This post is first of a series of “reminders” that will help your Xamarin.Forms apps become as performant as possible. This time we will use Fast Renderers to squeeze additional performance from our apps when running on Android.
In this article we will see how to modify the default icon and text of the built-in Settings item in UWP’s NavigationView.
