Xamarin.Forms - Send Email Using SMTP

Xamarin.Forms code runs on multiple platforms - each of which has its own filesystem. This means that reading and writing files are 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.

Use SMTP to send and receive mail messages. SMTP provides a set of protocols that simplifies 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.

Start by creating a new Xamarin.Forms project. You’ll learn more by going through the steps yourself.

Choose the Xamarin.Forms App Project type under Cross-platform/App in the New Project dialog.

Name your app, select “Use Shared Library” for shared code, and target both Android and iOS.

You probably want your project and solution to use the same name as your app. Put it in your preferred folder for projects and click Create.

You now have a basic Xamarin.Forms app. Click the play button to try it out.

Go to MainPage.Xaml and write the following code.
