New to asp.net i am trying to run the project described in asp.net zero docs using visual studio 2017.
When i build the project , i get warnings telling the absence of certain assemblies in the project:
System.RunTime
System.ObjectModel
System.Collections
System.Runtime
Searching for a solution i deleted the package folder and then rebuilt the project but the same issue repeared. i find that i can download the assemblies using package manager with help of nuget Gallery website , however when i install a missing package i get a message telling that the package already exist !!?
The package 'System.Collections.4.3.0' already exists in the project 'src \ Acme.PhoneBookDemo.Mobile.Droid'
what do you suggest to fix that problem ? or that is just a warning and it isn't important ?
