VB .net Accept Self-Signed SSL certificate

I'm searching for a way to validate (or bypass validation for) self-signed SSL certificates using VB .Net. I found code to do this in C# and tried converting it into VB code, but I'm not having any luck.

Here is the C# code.

Here is what I tried:

Imports System
Imports System.Net
Imports System.Security.Cryptography.X509Certificates

Public Class clsSSL
Public Function AcceptAllCertifications(ByVal sender As Object, ByVal certification As System.Security.Cryptography.X509Certificates.X509Certificate, ByVal chain As System.Security.Cryptography.X509Certificates.X509Chain, ByVal sslPolicyErrors As System.Net.Security.SslPolicyErrors) As Boolean
Return True
End Function
End Class


Then before the Webrequest I have this line of code which gives me an error.

ServicePointManager.ServerCertificateValidationCallback = New System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications)


The error message is:

Delegate 'System.Net.Security.RemoteCertificateValidationCallback' requires an 'AddressOf' expression or lambda expression as the only argument to its constructor.

Answer

In VB.Net, you need to write

ServicePointManager.ServerCertificateValidationCallback = AddressOf AcceptAllCertifications
