There are many terms ruling the software industry today— dot NET framework, .NET Core and .NET which are all almost the same but used for different purposes, so one should know which to use. The journey that started back in 2002 with the establishment of the .NET framework has seen many transformations in the last two decades. 

One such transformation happened with the release of a cross-platform re-build of .NET framework—dot NET core back in 2016. But the question here is—why did Microsoft come up with this release and how has it helped and changed over the years?  

Let us dive in and find answers to all these questions together!  

The Evolution of the .NET

Evolution of the .NET

In the late 1990s, Microsoft got down to business with the .NET framework. The novel idea back then was to establish a platform based on what was called “managed code”—a code that can be run in a runtime environment.  

It became a necessity with a view to streamlining the development background and enabling engineers to avoid worrying about security checks, active memory assembly, and other low-level measures that C/C++ software engineers had to undertake. 

  • The .NET Framework Era 

In 2002, the first .NET Framework was launched, which included C# – a language for writing managed code, whose syntax was similar to C++. The framework was aimed for computers and servers running on Windows.  

It contained WinForms—a graphical user interface library, ASP.NET – a web framework, and ADO.NET for access to data, which were driven by Common Language Runtime or CLR for compiling and executing managed code. 

  • The .NET Core Era 

In 2014, Microsoft made a loud statement that .NET was changed quite drastically – .NET Core was developed, a cross-platform, cloud-friendly and open-source version of the framework. In the year 2016, .NET Core went out of release, and it became the top technology to choose for further .NET projects. Little by little, Microsoft started to port the existing services to interact with Core. 

Why is .NET Core Open Source?  

Now that you know what is .NET core, let us now discuss the reasons why Microsoft released dot NET Core open source. 

While talking to Wired in 2016, Julia Liuson, corporate vice president of Miscrosoft’s developer division, said, “the way to reach developers was through open source. So Liuson and company endeavored to make .NET more open than ever before, and that meant making it run not just on Windows, but wherever developers might want to use it.” 

In simpler terms, Microsoft made dot NET open source to ensure that it was adopted and used in more systems. Open sourcing Dot NET made Microsoft relevant to developers, and the company’s influence expanded beyond the Windows systems.  

Plus, open sourcing allowed for cross-platform development. As a result, .NET can now be run on non-Windows systems such as Linux and MacOS.

Difference Between .NET Framework and .NET Core Framework 

There are commonly two confusions—one is the difference between .NET and ASP.NET and the other is difference between .NET framework and .NET Core Framework.

Here, we will tell you how .NET framework is different from .NET Core framework:  

  • Open Source 

The entire Dot NET Core platform is open source and is released under MIT as well as Apache 2 licenses. On the other hand, only specific components of the dot NET Framework are open source. 

  • Cross Platform Support  

The other difference is that .NET Core runs on Windows, macOS, and Linux while .NET Framework only supports Windows. 

  • Architecture  

Considering its streamlined design, some subsystems such as code access security in the .NET framework are not implemented in dot NET Core.  

  • API Support  

Some parts of APIs (Application Programming Interface) in the decades-spanning dot NET Framework have not been ported over into the newer cross-platform dot NET Core. The API set will continue expanding with future .NET Core updates. 

So, .NET Core is a flexible, open-source framework for modern applications that works for all needs across environments. The .NET Framework only works for Windows. It also has a lot bigger API surface area. Needless to say, both of these frameworks have distinct significance in the software industry.
