After running yo aspnetcore-spa I chose angular and executing dotnet restore && dotnet run I try to open the url in the browser. Everything is looking good (style and stuff) but the bootstrap menu isn't working, if you make the page small you get the hamburger menu but it doesn't open on a click.
When you add the following code

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>

to the html it starts to work again, so i suspect something is wrong with the bundle and the bootstrap javascript isn't executed
