Top 20 C# courses for a long-lasting future in programming

“C# is dying”

“I will have no future if I study C#”

“By 2030, C# will be gone from the world of computing” …

Well, these are not my assessments about C#, or those of a tech guru. These are the usual murmuring sounds one hears when one talks about this programming language.  I am writing this blog to clear a lot of misconceptions about the features and abilities of this language, which should help you get an idea about the top 20 C# courses.

Before I get down to these topics and proceed to suggest the top 20 C# courses that will put you on the path forward, I want to categorically state these facts about C#:

C# is an evolving language:

This is evidenced by the fact that in the two decades of its birth, it has got along, if you like, with all the technologies that have emerged on the centerstage. Since it is a flexible and not a static language, it is extremely well-suited for all the current day technologies, such as Data Science, cloud, AI, ML, and what have you. C# was as well suited for all the technologies of the previous versions and eras. This is not surprising, when one looks at the very origins of C#. Microsoft designed this programming language making it a product that blended the best elements of java, C, and C++, which is the strongest reason to believe that anyone who makes the doomsday prophecy for C# is missing the mark by miles.

It continues to adapt:

In line with the point above, let us take into account the fact that far from being rigid, C# has only got better with each avatar. Every new version that has come out from the Microsoft stable has included something of significance for C#. This guarantees that C# is not a flash in the pan.

It combines superbly with .NET:

C# works with .NET, which is currently in its fifth version (.NET 5). Now, why is this point relevant to this section of this blog? Here it goes: .NET 5 is a single open source software development framework with which software applications are built for range of mediums such as mobile, desktop, web, cloud, IoT and lots other. This means that so long as we continue to use these, .NET, and by extension, C#, is going to be in use.

It is ideal for building games:

Well, we are all game addicts in varying degrees! It is difficult to resist the magic of games. Around a third of all top games are built on the Unity engine. C# is one of the most popular languages for creating games using Unity. This makes it a terrific tool for creating games. As gaming continues to grow at a breakneck speed, it is natural to expect C# to grow too.

In addition, it comes with its usual, core characteristics, which are:

• It is scalable.
• It is compatible with most other programming languages, which makes it quite a pal of these.
• It integrates completely with the .NET library.

So, with these strong factors in its favor, does it make sense to fear for the future of this programming language? The strongest indicator of the mettle it is made up of lies in the fact that it continues to remain the fourth or the fifth most popular programming language in the world-depending on which index you are looking at-something of a feat considering that it has been around for so long.

If nearly 30 percent of professional developers use it (as of 2021), and if it still commands a pay of between $92,000 and $116,000, one has to hail its longevity and endurance!

So, which are the factors that have made C# what it is? Let us examine some of them:

• It is a structured, component-oriented, multi-paradigm, yet simple and readable programming language that supports all Microsoft products.
• You can build powerful tools using it.
• With there being no type conversion in it, it completely prevents data loss.
• It works well with most codebases, which is another feather in its cap.
• It is a master at resolving version control issues, making programming faster.
• It is a lot less expensive to maintain it compared to most other languages.
• And yes, it comes with its own garbage collector.
• It is flexible, although C++ beats it on this score.

Does all this mean that C# has no drawbacks? It does. Let us take a look at some of these too:

• One factor that goes strongly against C# is that its execution speed is not as fast as one would expect.
• C# lacks an independent compiler.
• It blocks access to the system’s hardware, something that some programmers frown upon.
• Being from Microsoft, its priority is on the Windows platform, which means it gives relatively less importance to other platforms it may be required to work on.

Now, with this much said about C#, let us now turn our attention to the top 20 C# courses, which we hope, will place you up the ladder to your growth in computer programming:

This software architecture course is essentially about how C# developers can build Dependency Injection (DI) with IoC-Containers. For the uninitiated, a dependency injection is a bunch of techniques with which a developer supplies dependencies to objects.

DI can be quite confusing, if one fails to grasp the fundamental concepts behind it. It is dichotomous, because one aspect of it, namely, passing dependencies via constructors applying the constructor engine, appears simple. Yet, as one goes to the next level, that of using DI or IoC (Inversion of Control) Containers, things can get a bit complicated. With this course, you will be able to build a solid foundation in software architecture applying Dependency Injection with IoC-Containers, which will help overcome these shortcomings.

The tutor for this course will familiarize you with the frameworks which perform DI automatically. This is the root of the issue, really, because once you understand how to set up a DI in the application root, you will have got a clue to understanding an extremely important notion, which will resolve all the dependencies it knows about in the runtime.

By combining the theoretical aspects with practical, hands-on methods, this course covers all aspects relating to DI and Inversion of Control. It teaches you the following topics:

• Introduction to Inversion of Control
• Dependency Inversion Principle (DIP), Inversion of Control (IoC), Dependency Injection (DI),
• Dependencies and their types, Pure DI and IoC-Containers, Service Locator
• The Architectural Implications of Dependency Injection
• DI-related Anti-Patterns & Refactorings:
• Control Freak, Hidden Dependencies, Temporal Coupling
• Constructor Over-Injection and how to avoid it
• Ambient Context, Facade Service, Property Injection vs Bastard Injection, Cyclic Dependencies
• Refactoring Example of an existing code base applying Dependency Injection
• How to reap the fruits of DI
• DI-Containers (IoC-Containers):
• Overview, Unity, Late Binding with Unity, Aspect-Oriented Programming (AOP), Interception vs Pure DI vs AOP Tools
• Setting up a bootstrapper with Unity, Autofac and Castle. Windsor.

This course will give beginner to intermediate level programmers a proper understanding of the WPF and XAML concepts and tools that they will need to build fully functional UI-applications using the modern UI-building framework, Windows Presentation Foundation (WPF).

WPF being a very expansive platform, this course includes only the topics needed for developing a full-fledged Windows UI-application. It leaves out a few advanced topics such as interoperation with Windows Forms, skinning, creating custom markup extensions, etc.

Learners will gain a deep understanding of the WPF platform. One of the aspects they will learn is how the layout process really works. With this understanding, they will be able to compose XAML quicker. The combination of theory and practice that this course has will help learners overcome challenges, such as the events system of WPF, which can be quite baffling for someone who doesn’t have a clear and deep understanding of how it works in practice.

This course will cover:

• Basic notions of UI-development
• Controls
• Layout
• Data-Binding
• Core-Types of WPF
• Events and Dependency Properties
• Templates
• Resources
• Styles
• User Controls
• Custom Controls
• WPF application model (threading model, app life-cycle).
