The remote certificate is invalid according to the validation procedure with self-signed certificate

I'm getting the error `The remote certificate is invalid according to the validation procedure when requesting an URL on my local development machine.

I already looked here.

But I can't find the VB.NET code for this C# code:

ServicePointManager.ServerCertificateValidationCallback += (o, c, ch, er) => true;

OR

// Put this somewhere that is only once - like an initialization method
ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(ValidateCertificate);
...

static bool ValidateCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
{
   return true;
}

Can someone help me with the translation of this code? I tried the translators converter.telerik.com and carlosag.net but those fail.

Rather than just translate let's first determine what this line does

 ServicePointManager.ServerCertificateValidationCallback += (o, c, ch, er) => true;

The MSDN docs says that ServerCertificateValidationCallback is a property of type RemoteCertificateValidationCallback

RemoteCertificateValidationCallback is a delegate with this signature

'Declaration
Public Delegate Function RemoteCertificateValidationCallback ( _
    sender As Object, _
    certificate As X509Certificate, _
    chain As X509Chain, _
    sslPolicyErrors As SslPolicyErrors _
) As Boolean

This (o, c, ch, er) => true; is a lamba expression with the signature RemoteCertificateValidationCallback and always evaluates true.

To do the same in VB.NET it's

ServicePointManager.ServerCertificateValidationCallback = Function(o,c,ch,er) (true)

This article will help will you with the second part, but it's the same idea.
