Can't restore NuGet Packages

Question

I downloaded a Xamarin Solution from TFS and now need to restore the NuGet packages. I tried to do it like this :

Update-Package -reinstall -Project ProjectName

But it didn't work and I got this message:

This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them.

How can I restore the NuGet packages? I tried to manually download android_m2repository, Clean Solution, delete bin/obj, rebuild - NOT WORKING, still :

An error occurred trying to install required android components on Project

UPD : I tried also Update-Package –reinstall - not worked :

This project references NuGet package(s) that are missing on this computer.

Solution 1

I just updated my Visual Studio 2017 from 15.6.4 to 15.7.2. It helped with packages, in my case.

Solution 2

Right-click on the Solution and click Restore NuGet Packages

Or try running this command in the folder that has your solution file:

dotnet restore

Or

nuget restore

Solution 3

I had similar issues once where it turned out that the Android SDK that was referenced was not installed. Maybe look in that direction?

Another way of fixing your issue: All you need to do is create a NuGet.Config file next to your .sln file, containing: <?xml version="1.0" encoding="utf-8"?> <configuration> <packageSources> <add key="nuget.org" value="nuget.org/api/v2" /> <add key="aspnetwebstacknightlyrelease" value="myget.org/f/aspnetwebstacknightlyrelease" /> </packageSources> </configuration>

when i did so, i got new error : NuGet Package restore failed for project -myproject-: Unable to find version '1.0.39.113' of package..

Is that package in a private NuGet feed? If so you might need to get login details or access to the private NuGet feed

I drop this package and Restore nuget : All packages are already installed and there is nothing to restore. but when I try to Build project get error again -> This project references NuGet package(s) that are missing on this computer.

Since "All packages are already installed" what if you clean the solution, delete obj/bin folders, and Unload/reload projects?

dotnet restore works but nuget restore not. what is the difference?

As @Сергей Notes, none of these suggestions does anything at all.
