What exactly is the difference between .NET Core and ASP.NET Core?

Are they mutually exclusive? I heard ASP.NET Core is built on .NET Core, but it can also be built on the full .NET framework.

So what exactly is ASP.NET Core?

ASP.NET Core using .NET Core - all dependencies are self-contained, can use most NuGet packages, can't use Windows-specific packages, can execute on Windows, Linux, and Mac.

ASP.NET Core using .NET Framework - most dependencies are self-contained, only executes on Windows, will have access to Windows-specific NuGet packages, needs the .NET framework version which is targeted installed on the machine.

The .NET Framework is on its last release. There will not be another one after 4.8. Microsoft will continue with .NET Core. From this time you should prefer .NET Core on your projects.

Official update (source):

.NET 5 is the next major release of .NET Core following 3.1. We named this new release .NET 5 instead of .NET Core 4 for two reasons:

  • We skipped version numbers 4.x to avoid confusion with .NET Framework 4.x.
  • We dropped "Core" from the name to emphasize that this is the main implementation of .NET going forward. .NET 5 supports more types of apps and more platforms than .NET Core or .NET Framework.

ASP.NET Core 5.0 is based on .NET 5 but retains the name "Core" to avoid confusing it with ASP.NET MVC 5. Likewise, Entity Framework Core 5.0 retains the name "Core" to avoid confusing it with Entity Framework 5 and 6.

.NET Core is the next evolution of the .NET Framework, that allows Microsoft technology to be hosted on other OS platforms, rather than Windows.

ASP.NET is the web framework provided by Microsoft for building:

  • server-side rendered web pages/websites
  • server-side components for SPAs
  • MVC-fashion apps
  • web services/web APIs/microservices

ASP.NET runs only on Windows platforms.

Since .NET Core was created to provide the capability of running Microsoft tech on top of Linux/macOS, it implies that ASP.NET Core is the evolution of ASP.NET in the direction of multi-platform support.

In conclusion:

ASP.NET Core runs on both .NET Core and .NET 5.0, on top of multiple OS platforms: Windows, Linux & macOS.

ASP.NET 4.x (ASP.NET/ASP.NET MVC) runs on the .NET Framework only, on top of Windows OS.
