Originally created by @ulbhudda on 1/22/2017

I generated with new aspnetcore-spa and chose the Angular 2 2017 preview-3 template (.csproj) when generating the project (hit enter for everything else [yes]). When I tried to open the new .csproj with VS2017 RC I am not able to load the basic project and get an error. picture below

ng2-vs2017rc-error

When I open the .txt file listed by VS2017 I see the following stack trace. Not sure what I might be doing wrong.
