In many cases when coping solution from one computer to another or especially if Visual Studio version is changed, errors occur that prevent automatic packages restoring and their dependencies. Therefore, to be able restore required packages try the following:

1. Open developer command prompt for Visual Studio.
2. Go to your solution directory and run dotnet restore .

Sometimes it's enough to remove and reinstall the required package from Visual Studio using the NuGet Package Manager .
