What is meant by ASP.net Version 2.0?

Question

What precisely do we mean by ASP.NET version 2.0 ? Is it the version lined with .net CLR version 2.0 ?

What about aspnet_isapi.dll and aspnet_wp.exe ? How do they fit in with respect to the versions 1.1 / 2.0 / 3.5 of the .net framework?

.NET 3.5 uses CLR 2.0. Does that mean nothing changes in ASP.NET 3.5 except for additions to the Class Libraries ?

Answer 1

ASP.NET 2.0 is the framework that shipped with .NET 2.0 (and thus CLR 2.0). In most ways, this number currently aligns most closely with the CLR version, in that although .NET 3.0 / .NET 3.5 add extra assemblies that can (and are) used by ASP.NET applications, there is no new ASP.NET version number.

Re your last point... "nothing changes"... well, the code that runs is largely dictated by the class libraries. So; yes, there are new dlls, and minor tweaks to the older dlls. But indeed, the core technology itself remains more or less the same.
