Can't install nuget package provider in powershell core 6.2.0

Question

I have webjob in azure. I try to install Az module to powershell core 6.2.0 using the following code:

using (PowerShell ps = PowerShell.Create())
{
    ps.Runspace = runspace;
    ps.AddScript("Install-Module -Name Az -AllowClobber -Scope CurrentUser - 
    Force;");
}

But in azure webjob console log I get an error about installing nuget package provider. Then I try to install NuGet package provider using the followeing command:

ps.AddScript("Install-PackageProvider -Name NuGet -MinimumVersion '2.8.5.201' -Force;");

But I get the following error:

What is wrong with it? How to install package provider to powershell core? Or how to install Az module without nuget? Help, please)

Answer 1

This might also seem to work. Have you tried this option?

Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force
