nugetPackages .netcore 3.0 missing in another machine

I have built a .netcore3.0 project on one machine and then transferred it to another standalone machine.

I copied all of the "Nugets" to "programFiles(x86)\Microsoft SDK's\nugetPackages"

the .csproj file includes the packageReference but when building the project I get the Errors:

Unable to find package <packageName> .No package exist with this id in source(s):Microsoft Visual Studio Offline Packages

also running CLI command dotnet list package returns: "[netcoreapp3.0]No packages were found for this framework."

does anybody know how to copy the nugetPackages with the folder itself like I Know you can do in .net Framework?
