The general idea of .NET as a platform is easy to understand. The naming of .NET Core, .NET Framework, ASP.NET, etc. and the difference between them is not.

[oblio]

.NET Framework = the whole shebang, the full runtime including Windows-only bits.

.NET Core = portable subset of .NET Framework. Therefore not entirely compatible with .NET Framework.

ASP.NET Core = portable rewrite of ASP.NET. AFAIK not fully compatible with previous versions.

iirc asp.net core does not contain the web framework part, just the server stuff
