Nuget offline packages with dependencies ubuntu

I need to download nuget packages from ubuntu to Windows, for offline download, which means all dependencies for a package should be download as well.

To use nuget:

sudo apt-get install mono-completewget https://dist.nuget.org/win-x86-commandline/latest/nuget.exe

Then download with mono nuget.exe install PACKAGE -version=VERSION.

The above command doesn't always download all dependencies and I don't understand why.

For example I needed System.ServiceModel.Http package with version 4.8.1 for .net standard so I executed the command

mono nuget.exe install System.ServiceModel.Http -version=4.8.1

and I got the errors:

Unable to find package System.Security.Cryptography.Cng with version (>=4.7.0)
Unable to find package System.Windows.Extensions
Detected package downgrade: System.ServiceModel.Primitives from 4.8.1 to 4.5.3. > Reference the package directly from the project to start different version

and more errors of type Detected package downgrade...

There is no download of Visual Studio for ubuntu so I can't create a solution and download nuget packages and then take the packages from nuget cache.

How can I download the wanted package with all dependencies for the wanted framework in one time, and also the packages that prevent downgrade in others?

Thank you!
