I have used NuGet to install the SendGridMail and SendGrid.SMTPApi libraries and my project references them. On compiling I get the error:\r\n\r\nSendGrid.SmtpApi.IHeader' is defined in an assembly that is not referenced.\r\n\r\non the line:\r\n\r\nmyMessage.Header.SetTo(new List<string>()...\r\n\r\nEverything else compiles fine, and when I use intellisense it shows that SetTo is available on myMessage.header.\r\n\r\nCheers - Gerard"}}
