What is ASP.NET CORE? core is a free and open source web framework used to develop the next generation of ASP.NET applications. ASP.NET Core is developed and powered by Microsoft as well as the community user base

It is a modular Framework that has the capability to run on legacy .NET Framework that runs on Windows as well as on cross platform systems

Originally it was called next version and then later it was supposed to be called 5 when it is ready. However, Microsoft later changed the name to ASP.NET core during the first release. The first version was released on 17th may 2016 

As of this video recording asp .NET core 2.0 is being used and it was released on 14 August 2017

The first question that comes into our mind when we need to use core as we have The Legacy applications.  If you take a look at the comparison table below given by Microsoft it’s fairly listed out when we need to choose core against ASP.NET

Build for Windows, macOS, or Linux Build for Windows
Razor Pages is the recommended approach to create a Web UI with ASP.NET Core 2.0. See also MVC and Web API Use Web Forms, SignalR, MVC, Web API, or Web Pages
Multiple versions per machine One version per machine
Develop with Visual Studio, Visual Studio for Mac, or Visual Studio Codeusing C# or F# Develop with Visual Studio using C#, VB, or F#
Higher performance than ASP.NET Good performance
Choose .NET Framework or .NET Core runtime Use .NET Framework runtime

In spite of these points, we can say that .NET Core is not a replacement for .NET Framework and we still need to use the .NET Framework applications when we need to use third party like .NET libraries where Nuget packages which are not available for any .NET Core apps.

We still need to use ASP.NET as we don't have capability of WCF service implementation using core at this point of time. However, the Core web applications can consume the WCF Services and they should not be a problem in the application development from the front end

Windows workflow Foundation related services and WCF Data Services are only available in .NET framework and Microsoft doesn't have any plans to bring this to ASP.NET Core

The windows presentation Foundation is still running on the and there are no plans to put them to the .NET Core.

Why should I choose and use ASP.NET Core? 
  • Cloud based application development is current trend and using core along with a blend of cloud is an additional advantage for any developer to learn Core applications
  • Microsoft is moving towards community based application development rather than their traditional application development  which brings the change faster to the core  and gives an advantage over the traditional applications
Why is Microsoft Promoting Core?
  • Developers don’t stick to SQL server development
  • Platform Independence is in demand
  • Flexibility in hosting apps to Amazon/Google/Microsoft clouds 
  • Community development brings rapid changes
I hope the above points clarify why Microsoft is proceeding towards the direction of ASP.NET Core

Features of ASP.NET Core
  • Improved support for cloud development
  • Nuget based support
  • High performance
  • Modular framework
  • Cross platform compatibility
  • Flexibility of being open source
  • Hosting independence
  • Built-in support for dependency injection
  • Support for JSON based configuration
  • Unit testing with
