The "FindConfigFiles" task failed unexpectedly, => System.IO.PathTooLongException:

[bastienJS]

I am running Visual Studio 2015 Pro Update 2.
I use windows 10 64bit, nodejs 6.1.x and npm 3.8.9
I have created a asp.net core RC2 project.
I created a angular 2 sample app via run the angular 2 CLI: 'ng new "projectname"' in the wwwroot folder.
Now I get build errors and I can not solve that problem...

This problem does not occur when I create the same project in the WebStorm IDE. There I can build and run the app fine!

The problem seems to be between TypeScript, Visual Studio and node_modules.

DNX is no longer supported. I recommend moving to ASP.NET Core RC2 bits with dotnet CLI.

[sudhir9p]

This issue got resolved??? I'm facing same issue ,

@sudhir9p DNX is no longer supported. I recommend moving to ASP.NET Core RC2 bits with dotnet CLI.

[jakejscott]

This is still an issue even though it's not related to DNX, the issue needs to moved to the Tooling repo or TypeScript

[jakejscott]

Actually npm 3 is finally out which doesn't use really long paths... so that fixed it for me

[max-favilli]

@superlogical upgrading to npm 3 fixed that for me too. Just for anyone else having the same issue and ending up reading us here, a reboot was needed.
