My new blog -


My blog is now located at

I was blocked from Google Adsense for illegal clicks on this blog a long time ago. I tried to ask for a second chance but they say that they are protecting the trust that their customers give to them.

Solution to error on "kpm restore": Unable to locate [package]

When I tried to run "kmp restore" on a vNext project I got these error messages like in the picture below:

The solution is to create a Nuget.config file that contains the package source for vNext at the root of your solution

 <add key="AspNetVNext" value="" /> 
 <add key="" value="" /></packageSources>
