'WeakMap' is undefined

[im1dermike]

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.

If you need IE10 support, please install core-js/shim as described here: #854 (comment)

As for making things work out of the box, we have an issue tracking IE9-11 support here: #484

@SteveSandersonMS Thanks for your replied. I installed corejs and added import 'core-js/shim'; to the top of my boot-client.ts file, but now I get a "Can't resolve 'core-js/shim'" error.

[SteveSandersonMS]

@im1dermike Then I don't know why that would happen - it should be possible to resolve core-js/shim. I'm afraid you'll have to track that down yourself :(

[im1dermike]

@SteveSandersonMS Should I be running:

npm install --save corejs

as described in Issue 854 or

npm install --save core-js

[SteveSandersonMS]

Ah yes, that's it - it's core-js and not corejs. I've updated the comment in #854 to match. Well spotted!

@SteveSandersonMS Oof. Now I'm getting the following error in IE:

SCRIPT5022: Error: DI Error
vendor.js, line 104835 character 13

Works fine in other browsers. Anything you can do to point me in the right direction?

I can confirm the issue with IE. Following the shim installation, DI error is in place. Looking forward for possible solution.
