ASP.NET Core is an open-source modular web-application framework. It is a redesign ofASP.NET that unites the previously separateASP.NET MVC andASP.NET Web API into a singleprogramming 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 thecross-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 supportWebAssembly and since version 5.0, it has dropped support for some old web browsers. While currentMicrosoft Edge works, thelegacy version of it, i.e. "Microsoft Edge Legacy" andInternet Explorer 11 was dropped when you use Blazor.[6]

Originally deemedASP.NET vNext, the framework was going to be calledASP.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.[24]
