In visual studio 2017 please do following steps:

1) select Tool=>Options=>NuGet Package Manager=> Package Sources then uncheck Microsoft Visual Studio Offline Packages Option.

Cause of this defect: you have to remove the injected Nuget in file explorer. Solution: Once you remove that Nuget in your system, then remove from following location. select Tool=>Options=>NuGet Package Manager=> Package Sources then uncheck Microsoft Visual Studio Offline Packages Option

Answer 3

Select Tools > NuGet Package Manager > Package Manager Console

And then Run:

dotnet restore <project or solution name>

Answer 4

If @mostafa-bouzari suggestion doesn't help, check carefully in 'Error list' or 'Output' windows for errors why NuGet cannot restore, e.g. because of net problem if you're behind proxy.

Answer 5

Another one, if by any chance you're using Dropbox, check for Conflicted in file names, do a search in your repo and delete all those conflicted files.

This may have happened if you have moved the files around.

Answer 6

In my case the error was the GIT repository. It had spaces in the name, making my project unable to restore

If this is your issue, just rename the GIT repository when you clone

git clone http://Your%20Project%20With%20Spaces newprojectname
