Coming to a future version of IntraWeb. We did some testing in the past, now we are moving beyond testing. Check out TypeScript.
When? Well you can use TypeScript now with any IntraWeb version. But what we are talking about here is a new set of libraries for use with IntraWeb to bring IntraWeb far forward. These changes are slated for IntraWeb 17. There will be no 15, and 16 is focused on Linux.
