Issue with kpm restore when trying to run vNext sample app

Question

So i am following the instructions here for getting started with vNext.

All goes well until i get to the step where i have to run kpm restore and i get the following output in my console window:

C:\GitRepo\vNext\samples\ConsoleApp>CALL "C:\Users\jconway\.kre\packages\KRE-svr
50-x86.0.1-alpha-build-0421\bin\KLR.cmd" --lib "C:\Users\jconway\.kre\packages\K

Restore failed
One or more errors occurred.

Does anyone have a resolution for this?

Answer 1

Taking a look at what was happening with fiddler. I could see that it was trying to restore packages from my private feed. My private feed was returning 404 pages which was causing it to fail.

The solution was to open visual studio and go to Tools > Library Package Manager > Package Manager Settings... > Package Sources. Then i had to deselect all sources except for nuget.org and add https://www.myget.org/F/aspnetvnext/ as a package source.

Once i saved this i tried again and everything worked
