I just tried to open up my application generated using this tool in IE10 and I get the following error in my browser console:

SCRIPT5009: 'WeakMap' is undefined
vendor.js, line 112874 character 1

It seems to trace to this thread, but the only references to "WeakMap" in this solution is in \dist\main-client.js and \dist\vendor.js so I'm unclear on how to resolve it.
