ASP.NET Core is an open-source modular web-application framework. It is a redesign of ASP.NET that unites the previously separate ASP.NET MVC and ASP.NET Web API into a single programming model. [3] [4] Despite being a new framework, built on a new web stack, it does have a high degree of concept compatibility with ASP.NET. The ASP.NET Core framework supports side-by-side versioning so that different applications being developed on a single machine can target different versions of ASP.NET Core. This was not possible with previous versions of ASP.NET. ASP.NET Core initially ran on both the Windows-only .NET Framework and the cross-platform .NET. However, support for the .NET Framework was dropped beginning with ASP.Net Core 3.0. [5]

Blazor is a recent (optional) component to support WebAssembly and since version 5.0, it has dropped support for some old web browsers. While current Microsoft Edge works, the legacy version of it, i.e. "Microsoft Edge Legacy" and Internet Explorer 11 was dropped when you use Blazor. [6]

Naming

Originally deemed ASP.NET vNext, the framework was going to be called ASP.NET 5 when ready. However, in order to avoid implying it is an update to the existing ASP.NET framework, Microsoft later changed the name to ASP.NET Core at the 1.0 release. [20]

The .NET Framework is a proprietary software framework developed by Microsoft that runs primarily on Microsoft Windows. It was the predominant implementation of the Common Language Infrastructure (CLI) until being superseded by the cross-platform .NET project. It includes a large class library called Framework Class Library (FCL) and provides language interoperability across several programming languages. Programs written for .NET Framework execute in a software environment named the Common Language Runtime (CLR). The CLR is an application virtual machine that provides services such as security, memory management, and exception handling. As such, computer code written using .NET Framework is called "managed code". FCL and CLR together constitute the .NET Framework.

OWIN is a standard for an interface between .NET Web applications and Web servers. It is a community-owned open-source project. Prior to OWIN, Microsoft's ASP.NET technology was designed on top of IIS, and Web applications could not easily be run on another Web server. OWIN aims to decouple the relationship between ASP.NET applications and IIS by defining a standard interface. Developers of Web servers can be sure that, if they implement OWIN correctly, ASP.NET applications will run on their server. Similarly, new Web frameworks could be developed as an alternative to ASP.NET. As long as they target OWIN, they will run on any OWIN compatible Web server, including IIS.

Microsoft, a tech company historically known for its opposition to the open source software paradigm, turned to embrace the approach in the 2010s. From the 1970s through 2000s under CEOs Bill Gates and Steve Ballmer, Microsoft viewed the community creation and sharing of communal code, later to be known as free and open source software, as a threat to its business, and both executives spoke negatively against it. In the 2010s, as the industry turned towards cloud, embedded, and mobile computing—technologies powered by open source advances—CEO Satya Nadella led Microsoft towards open source adoption although Microsoft's traditional Windows business continued to grow throughout this period generating revenues of 26.8 billion in the third quarter of 2018, while Microsoft's Azure cloud revenues nearly doubled.
