I tried to add a new Class library(.Net Standard) in Visual studio 2019. But I get this error message:
Unable to find package NETStandard.Library. No packages exist with this id in source(s): Microsoft Visual Studio Offline Packages.
I haven't added any code to this file yet. When I go to NugetManager I can see this message:
NetStandard.Library not available at this source
Can anyone please help me with this issue?
Your package source in visual studio is on the Microsoft Visual Studio Offline Packages. You should Go to Package Manager Settings (Tools > Nuget Package Manager > Package Manager Settings).
On the package sources section enter
Name : nuget.org
source :https://api.nuget.org/v3/index.json
add this package source to your visual studio and click ok.
