Version of IIS & .net framework

Is there an开发者_如何转开发y IIS version release after IIS 7.5? And is there any update for .NetFramework released after .NetFramework 4?

IIS is considered part of the operating system, so probably IIS vNext will only come when Microsoft releases its next version of Windows, which may not happen in the coming months. But once Microsoft provides public betas of it, you can test it out.

.NET 4 is still the latest, and like @Pawan pointed out, there are updates for .NET already, but SP1 is not yet announced.
