What's .NET?

.NET is an open-source development platform created by Microsoft for building different types of apps for many operating systems and devices.

.Net ecosystem Insights

By dint of the Open-Source collaboration, the .NET ecosystem has seen some significant growth in the last few years as highlighted below:

  • There are now over 5 million active developers in the Visual Studio Family Tools.
  • .Net core has ranked number 1 two years in a row as the most loved framework on the stack overflow developer survey.
  • Based on the rate of the pull of requests and issues and how many accepted, the Cloud Native Computing Foundation (CNCF) tracks the highest velocity projects on all GitHub.
  • C#  is the top five languages on GitHub.
  • ASP.NET core is > 10X faster than Node.JS.
