Why C# is the Powerful Programming Language

Meet C#!

C# has expressive syntax and is easy to learn. Everyone who worked in C, C++ or Java recognizes curly braces. Familiar with one of these languages? Then you will quickly start productive work in C#.
The syntax of the language eliminates the complexity of C++ and provides such powerful features as nullable type values, enumerations, delegates, lambda expressions, and direct memory access. C# supports generic methods and types that increase type safety and performance. Iterators allow collection creator classes to define custom iteration behaviors that are easy to use in client code. Language - integrated query (LINQ) expressions make a strongly typed query a first-class language construct.
C# is an object-oriented language, which means it supports encapsulation, inheritance, and polymorphism. A class can inherit directly from one parent class, but it can implement any number of interfaces. Methods that override virtual methods in the parent class require the use of the override keyword to prevent accidental overriding.
In addition to all OOP goodies, the C# language facilitates the development of software components through several innovative language constructs:

• Encapsulated method signatures, called delegates, include type security alerts
• Properties serve as accessors to the variables of the closed parts
• Attributes provide declarative metadata about types at runtime
• XML line documentation comments
• The Language - Integrated Query (LINQ) provides built-in query capabilities between different data sources

Need to interact with other Windows programs, for example, with COM objects or with the built-in Win32 DLL? Do this with C # through the Interop process. Interop allows programs written in C # to do almost everything available to programs written in C ++. C # even supports pointers and the concept of "unsafe" code for cases where direct access to memory is absolutely critical.

Xamarin: mobile development in C#? Easily!

Many people think of developing for Android and iOS in the context of such embedded languages ​​as Objective-C, Swift, Java, and Kotlin.
Xamarin allows you to develop in C # using libraries and runtime that run on iOS, Android and Windows. This compiles embedded (not interpreted) applications with sufficient performance for games.

Xamarin combines all the features of embedded platforms and adds several powerful features:

• Full binding to the basic SDK: Xamarin contains bindings to almost all the basic platform SDKs from iOS and Android. In addition, these bindings are strongly typed, which makes it easier to use and navigate, and also includes strict type checking during compilation and development.
• Interop for Objective-C, Java, C and C ++: Xamarin contains tools for directly calling the Objective-C, Java, C, and C ++ libraries, which means you are free to use third-party code without reinventing the wheel. This way, you will take advantage of the existing iOS and Android libraries written in Objective-C, Java, or C / C ++.
• Modern language constructs: Xamarin applications are written in C #, a modern language that contains significant improvements over Objective-C and Java. For example, features of dynamic language, lambda, LINQ, parallel programming functions, generics and much more.
• Modern IDE: Xamarin applications use .NET BCL, a large collection of classes that has features such as XML, databases, serialization, IO, strings, and network support. Existing C # code can be compiled for future use in the application, which opens up access to thousands of libraries that can do what is not available in BCL.
• Base Class Library (BCL): Xamarin uses Visual Studio on macOS and Windows. Both versions have such modern features as code completion, project management system, template library, built-in version control.
• Mobile cross-platform support: Xamarin supports iOS, Android and Windows. Applications can have up to 90% of the total code. The Xamarin.Mobile library offers a unified API for accessing the resources of all platforms.

C# programmers can develop cross-platform mobile applications on Xamarin!

C# is used in machine learning

Do you already have experience in .NET and want to learn machine learning? ML.NET is an open-source cross-platform machine learning framework.
It allows you to create custom ML models in C # without leaving the .NET ecosystem. You can use all your experience and knowledge accumulated during your work with .NET to integrate machine learning into existing desktop, game, mobile or web applications, and even in IoT devices.

Here's what you can do with ML.NET:

• Classification/categorization: Separate user feedback into positive and negative categories automatically.
• Regression/Prediction: Continuous values: Predict property prices based on size and location.
• Anomaly Detection: Detect fraudulent banking.
• Recommendations: Offer products to online shoppers based on their purchase history.

About the games

Unity is the most popular indie game development engine and it uses C ##. Interestingly, the engine itself is written in C ++, so it frees the programmer from the need to understand the speed of execution, which is ideal for beginners.

There are other engines with C# support:

• Monogame allows you to "write a game once and play everywhere"
• WAVE - cross-platform engine
• Xenko is a fairly powerful cross-platform engine
• Duality only supports 2D
• Xna - the official engine from Microsoft
• Flatredball is a 2D engine

All of these engines allow you to write game code in C#, but Unity has definitely taken a special place in commercial development. Just remember such games as Rust and Forest - they are written in Unity, and therefore in C#.

How does all this affect the labor market?

Perhaps C# programmers did not rush to write mobile or web applications. But look what opportunities open up for those who already know C#. In addition, Microsoft plans to combine the .NET Core and the .NET Framework by 2021 with features such as the Windows Presentation Foundation (WPF).
C# programmers are no longer limited to the Windows platform. Today, they can safely try themselves as mobile, game or web developers.
The benefits for companies and startups are even more obvious: you can use one development team for all types of applications. Code support is improved, as the entire database is written in C #, including the server backend.
We should also mention machine learning - these are huge prospects for C# developers and for the language itself.
And all this you can do in Visual Studio! :)
