typescript 2 on-demand compilation

[kataik]

TypeScript Version: 2.0 beta

Environment and stack: Windows 10, Visual Studio 2015 update 3, .NET Framework 4.6.1, Web Core RC2, Node.js 4.5.0, Gulp

Task Runner Explorer used to properly identify and execute tasks written in typescript using the typescript-node (0.1.3), typescript-register (1.1.0) and typescript-require (0.2.9-1) node packages. This no longer works after upgraded to typescript 2.0 beta. Task Runner explorer fails to properly update its task list (although still recognizes the gulpfile.ts as source).

When I try to execute one of the tasks, I get the following exception during runtime:

TypeScript isn't anywhere in that stack trace; we do not own typescript-node, typescript-register, or typescript-require. Please log a bug with the appropriate external component.

@blakeembrey any thoughts?

@kataik I would recommend using ts-node. Both typescript-register and typescript-require haven't been updated for a long time (see theblacksmith/typescript-require#36 and https://github.com/pspeter3/typescript-register#typescript-register---). On top of that, if you installed typescript-node you should also see it is deprecated (both on the README and an NPM warning) and is called ts-node.

Thanks a lot, it works fine now. The problem was that typescript-register and typescript-require were still there and gulp tried to use them. Removed, now works properly. Sorry for the invalid issue.
