.NET Core is the open source version of the Microsoft Framework .NET. It was released in 2002 to go hand in hand with Visual Studio.NET and it was the latest version of Microsoft Visual Studio IDE. This was an alternative to the .NET Framework and released with cross-platform applications functionality in order to give developers and business the flexibility to release products with a wider variety in the implementation department. The contributions for it to become open source came from the .NET Foundation with Microsoft back in 2014. This framework is used in many apps, tools, new platforms and hosting services. Multiple companies made contributions to the framework on GitHub and provided guidance and direction.
Whether you are working in C#, F#, or Visual Basic, your code will run natively on any compatible OS. The beauty in this is the different .NET implementations will be handling the heavy lifting for you. The framework power comes from its ability to adapt. It is designed to enable broad adaptability and compatibility to new platforms and workloads. It has several OS and CPU ports readily available.
The Core Framework can be defined by several key characteristics and they are:
. NET Core has two major components. The first component includes a small runtime that is built from the code base as the .NET framework CLR. The second component is a series of base class libraries. These libraries are largely the same code as the .NET framework class libraries but have been factored into the shipment of a smaller set of libraries. These libraries are shipped as a system.
To define .NET Core, you can begin by looking at the architecture which is made of up four main components:
.NET Core exposes APIs for many scenarios. A few examples are:
.NET Core provides compatibility with .NET Framework and Mono APIs by implementing the .NET Standard specification.
There are many frameworks built on top of the .NET Core. The key frameworks you should know are:
The differences between the .NET Core and the .NET Framework are:
In summary, .NET Core exists to fill the gaps that the .NET framework left open. You need to remember that Core is not a replacement for the .NET Framework. However, with enough time and dedication, you can use it to power your apps, tools, new platforms or hosting services on Linux, macOS or Windows.
To many, .NET Core is the foundation for Microsoft’s future. By providing developers with an open source version of its existing .NET Framework, a new era of much better product experience was ushered in. Whether you like it or not, Microsoft made it so that web, cloud, mobile, gaming or any form of application you can imagine was at your grasp with this powerful variant of the flagship framework. Microsoft continues to impact the tech industry after decades of doing so and we are all witnesses.
