That's not the same thing as ASP -- they are two totally different technologies, with only Microsoft in common. And Mono (the system used to run ASP.NET on Linux/CentOS) does not completely support ASP.NET either, so the code needs to target only those parts of ASP.NET that Mono supports (essentially, Framework 2 minus the Windows system calls, along with parts of MVC and AJAX, with major inconsistencies).
