I saw your question yesterday and looked it up on a regular basis in hope of someone answering it. Sadly, no one did, the good news though I've found a solution so I'm sharing it to you.
The IIS-ASPNET is still there and it enables ASP.NET 3.5. You still need IIS-NetFxExtensibility
. The difference lies in that those two now have an additional prerequisite, NetFx4Extended-ASPNET45
.
So if you want to enable ASP.NET 3.5 you need : IIS-ASPNET;IIS-NetFxExtensibility;NetFx4Extended-ASPNET45
For ASP.NET 4.5 you need : IIS-ASPNET45;IIS-NetFxExtensibility45;NetFx4Extended-ASPNET45
