C# is a simple yet powerful language for clearly expressing intent. It comes with a variety of operators that simplify the expression while keeping it easy to understand.
In this article, we’ll dive into the .. (dot-dot) operator, which has been gaining popularity in recent releases.
It is used in the following scenarios:
Introduced in C# 3.0, extension methods are a valuable feature for external types, especially when those types are sealed, such as string.
Roughly two decades later, C# has now finally unveiled support for extending everything.
With the release of .NET 10 Preview 3 (C# 14), it is now possible to define static methods, instance properties, and static properties too. Support for other members will be incorporated in future releases.
Syntactically, an extension method should be defined within a top-level static class. The type of its first mandatory parameter, the one qualified with the this keyword, determines the type being extended. Henceforth, this will be referred to as the receiver type.
All standard query operators of LINQ are defined as extension methods. They are defined in the Enumerable static class within the BCL (in the System.Linq namespace).
For example, the Where extension method applies to all types that implement IEnumerable<T>. Validations and optimizations aside, the typical implementation is as outlined below.

Basically, theming refers to managing a consistent look and feel across the app. An app can be themed in a variety of ways (MS Office and Visual Studio offer various themes). For mobile apps, the most significant themes are the Light and Dark modes, both of which are inherently supported by the OS. So, the app should have the capability to adapt to mode changes to the least.
Consulting the previous article on Styles is recommended as a foundation for Theming.
Excerpt from the preceding article:
Styles can be referenced through StaticResource or DynamicResource. The key difference is that the former is applied just once, while the lattter maintains a reference and adjusts to changes in themes.
It’s the month of May, so it’s time for Microsoft Build, its annual developer conference, where it’ll showcase the innovative features to the community.
It’s the age of AI, which is disrupting the status quo. So most of the sessions are scheduled along that line as expected.
For .NET MAUI, Blazor, and C#, these are the highly recommended sessions to watch.

A style is characterized by a collection of interrelated properties that aim to improve resource management within the application. It is defined as a list of Setters. A Setter has a property and a value.
Styles can be incorporated into the Resources property, of type ResourceDictionary, defined at the VisualElement level.

We’ll start with the Margin and Padding that effectively position the View.
Both the properties have been appropriately defined at the View level and are of the type Thickness, which is a structure that defines 4 important properties: Left, Top, Right, and Bottom.
