SendAsync(HttpRequestMessage, HttpCompletionOption) Send an HTTP request as an asynchronous operation. SendAsync(HttpRequestMessage, CancellationToken) Send an HTTP request as an asynchronous operation.
From the msdn documentation: "Sends an e-mail message to an SMTP server for delivery. These methods block while the message is being transmitted.". So yes it's synchronous.
Allows applications to send email by using the Simple Mail Transfer Protocol (SMTP). The SmtpClient type is obsolete on some platforms and not recommended on others; for more information, see the Remarks section.
smtpClient.send() will initiate the sending on the main/ui thread and would block. smtpClient.SendAsync() will pick a thread from the .NET Thread Pool and execute the method on that thread. So your main UI will not hang or block.

SendAsyc - Sends the specified e-mail message to an SMTP server for delivery. This method does not block the calling thread and allows the caller to pass an object to the method that is invoked when the operation completes. More details : SmtpClient.SendAsync Method
