Azure Functions - PlatformNotSupportedException unless you mannauly set IPEndPoint #133
Description
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;

Hi @msdickinson, thanks for letting me know!
Never worked with Azure functions yet but I'll take a look into it. Its a bit strange because that path shouldn't run if it is not Windows.
So that looks kinda like a bug
fixing #133
Removing UDP client pooling (#146)

This should be fixed with 1.6, I did not test it in azure functions though but the PlatformNotSupportedException should be ignored now.
That doesn't mean that the library will find a DNS server in Azure Functions so you still might have to manually configure the client unless you can use public DNS servers
