With so many of our students choosing Java as their weapon of choice, I found it appropriate to talk about .NET Core (dotnet core as people call it sometimes) and why we should be mastering C# and .NET Core framework.
But before that, let’s give it a little introduction. .NET Core is the newest framework in a long line of frameworks supporting C# (including .NET Framework, Xamarin and Mono). Even though it holds the name .NET, it is first of its kind. And if you’re considering why, let me explain. It builds native applications on all major operating systems! You saw it right. With .NET Core, you can build applications that work across all platform. But what’s new with that? Java works across platforms too.
To understand that we need to understand something first. Java works across platforms because JDK (the runtime for Java) works across-platform. Microsoft has a long history of rejecting Linux. So they made sure their frameworks didn’t work with it. But a few years ago Microsoft recognized that they were lagging behind because of this. To meet up to the challenges posed by it’s competitors, they created a runtime that works across operating systems and to populate that runtime, they created the .NET Core framework.
“But Simanto, that is all cool and stuff but that still doesn’t make it more exciting than others. Java does all those things.”
True. With this approach they basically caught up to Java. But then they took it another step forward. .NET Core introduced the Runtime Identifier (RID). With RID you can specify which operating system your project is targeting. When you build for publish, the project will create a NATIVE application. That means you don’t need the runtime in the environment to run this application. You can very well install a fresh copy of bare-boned Ubuntu 16.04 and get your application up and working. The entire runtime is packed with the application, along with the libraries. A native application is created which binds the runtime and any library you might have used, and run the app that you created.
There are tons of tools that do that for different languages with different runtimes. But .NET Team wanted this not to be just a tool, but a default on how you deploy your applications.
Another major thing that .NET Team introduced is the shared framework called .NET Standard. The way this framework works is that it allows libraries to work across all 3 major frameworks; .NET, .NET Core & Xamarin. Build your library once and it will work for mobile, web-apps or even windows-apps, without breaking a sweat.
Combine these features with the ability to use pointers exactly like how you might use them in C/C++, C-sharp tagged with .NET Core is a power house that, in my opinion, is set make its way to the top of the food chain.
