NET-3367 Fix S4830 AD0001: CertificateValidationCheck Syntax node is not within syntax tree #9795
Description
Description
When getting the certificate validation callback from a static method of a static class in a separate file which in turn calls another static method, the CertificateValidationCheck analyzer crashes with a System.ArgumentException: Syntax node is not within syntax tree (presumably because it can't find the method).
Workaround: Putting the validation class in the same file as it is used in, no error occurs.
Reproducer
Program.cs:
using var test = new SslStream(new MemoryStream(), false, CertValidator.GetCallback());CertValidator.cs:
public static class CertValidator
{
public static RemoteCertificateValidationCallback? GetCallback()
{
return (s, cert, chain, errors) =>
{
return Validate(errors);
};
}
private static bool Validate(SslPolicyErrors errors)
{
return errors == SslPolicyErrors.None;
}

Hi @patrick-achtbytes,
We have fixed this in the latest release of our analyzers. It is available now on SonarQube Cloud and will be available in the next SonarQube Server release.
