Use 'Connect-AzAccount' command of PowerShell in C#

Question

I want to connect to Azure the same way I log in using Powershell commands. Since I have not found any API to do that with .NET, I thought that a good idea would be to execute PS scripts with.NET.

I have already installed the Powershell for azure on my laptop

Install-Module -Name Az -AllowClobber

I also tried to use the 'Connect-AzAccount' command just with the Windows Powershell of my PC and it works fine.

So, I tried the following in Visual Studio:

using System.Management.Automation;

namespace AzureTestVM
{
    class Program
    {

        static void Main(string[] args)
        {
            PowerShell ps = PowerShell.Create().AddCommand("Connect-AzAccount");
            ps.Invoke();
        }
    }
}

The problem is that I get the following error :

Unhandled Exception: System.Management.Automation.CmdletInvocationException: Method
'get_SerializationSettings' on type'
