Xamarin.Forms - Send Email using SMTP

In this blog post,  you will learn how to send background Email with SMTP in Xamarin forms.

Introduction

Xamarin.Forms code runs on multiple platforms - each of which has its own filesystem. This means that reading and writing files is most easily done using the native file APIs on each platform. Alternatively, embedded resources are a simpler solution to distribute data files with an app.

SMTP (Simple Mail Transfer Protocol)

Use SMTP to send and receive mail messages. SMTP provides a set of protocol that simplify the communication of email messages between email servers.It is an Internet standard for electronic mail (email) transmission. SMTP is a part of the application layer of the TCP/IP protocol. The default TCP port used by SMTP is 25 and the SMTP connections secured by SSL, known as SMTPS, uses the default to port 465.Most SMTP server names are written in the form "smtp.domain.com" or "mail.domain.com": for example, a Gmail account will refer to smtp.gmail.com the gmail port number is 587.
