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.
