Hi, so I have been able to run in azure functions about a year ago but now I am trying again and finding failing.
System.InvalidOperationException: 'Error resolving name servers'
PlatformNotSupportedException: Registry is not supported on this platform.
var client = new LookupClient();
But the code below is functional. So again I assume this is in azure function not letting me grab the systems DNS settings, so I mannauly setting it works. Creating this here in case its useful for anyone but you can close the ticket.
var client = new LookupClient(NameServer.GooglePublicDnsIPv6);
var result = client.Query("google.com", QueryType.MX)
.Answers.MxRecords().Any()
? ValidateEmailDomainResult.Vaild : ValidateEmailDomainResult.Invaild;
