PowerShell 7 (x64) error

Lines 90 to 102 in 69988bc

	If ($Null -eq ([System.Management.Automation.PSTypeName]'TrustAllCertsPolicy').Type) {
	Add-Type -Debug:$False @"

	WebRequest request, int certificateProblem) {
	return true;
	}
	}

	}

It appears that PSVersion 7.1.1 isn't able to load or find the type/namespace for ICertificatePolicy. PSVersion 5.1.1 operates as it's been just fine. The error outputs are as follows.

I was able to get it to work with modifying lines 90-103 and replacing them with the following code.

    $certCallback = @"
    using System;
    using System.Net;
    using System.Net.Security;
    using System.Security.Cryptography.X509Certificates;
    public class ServerCertificateValidationCallback
    {
        public static void Ignore()
        {
            if(ServicePointManager.ServerCertificateValidationCallback ==null)
            {
                ServicePointManager.ServerCertificateValidationCallback += 
                    delegate
                    (
                        Object obj, 
                        X509Certificate certificate, 
                        X509Chain chain, 
                        SslPolicyErrors errors
                    )
                    {
                        return true;
                    };
            }
        }
    }

    Add-Type $certCallback

I have a similar issue and here is the peice of code which is erroring out

add-type @"
using System.Net;
using System.Security.Cryptography.X509Certificates;
public class TrustAllCertsPolicy : ICertificatePolicy {
    public bool CheckValidationResult(
        ServicePoint srvPoint, X509Certificate certificate,
        WebRequest request, int certificateProblem) {
        return true;
    }
}
"@
$AllProtocols = [System.Net.SecurityProtocolType]'Ssl3,Tls,Tls11,Tls12'
[System.Net.ServicePointManager]::SecurityProtocol = $AllProtocols
[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy

Based on your suggestion above I replaced my code with your code

$certCallback = @"
using System;
using System.Net;
using System.Net.Security;
using System.Security.Cryptography.X509Certificates;
public class ServerCertificateValidationCallback
{
	public static void Ignore()
	{
		if(ServicePointManager.ServerCertificateValidationCallback ==null)
		{
			ServicePointManager.ServerCertificateValidationCallback += 
				delegate
				(
					Object obj, 
					X509Certificate certificate, 
					X509Chain chain, 
					SslPolicyErrors errors
				)
				{
					return true;
				};
		}
	}
}
"@
Add-Type $certCallback


$AllProtocols = [System.Net.SecurityProtocolType]'Ssl3,Tls,Tls11,Tls12'
[System.Net.ServicePointManager]::SecurityProtocol = $AllProtocols
[ServerCertificateValidationCallback]::Ignore()

It is still erroring out although with a different error :
Exception setting "SecurityProtocol": "The requested security protocol is not supported."

Any suggestion on how this issue can be resolved?
