there example application @ http://www.codeproject.com/articles/1118189/crud-using-net-core-angularjs-webapi functions in chrome async calls seem fail in ie11. have tried adding/removing combinations of following

<meta http-equiv="pragma" content="no-cache">   <meta http-equiv="expires" content="-1">   <meta http-equiv="x-ua-compatible" content="ie=edge" />  <script src="../lib-npm/es5-shim/es5-shim.js"></script>  <script src="../lib-npm/es5-shim/es5-sham.js"></script>  <script src="../lib-npm/es6-shim/shims_for_ie.js"></script>  <script src="../lib-npm/es6-shim/es6-shim.js"></script> 

if open development tools in internet explorer , change emulation 10, page functions expected. (data in list updates on save) if change x-ua-compatible edge 10, call still fails.

no errors.
