In a Windows Forms project, I used the SmtpClient and MailMessage class in order to send information by email.
Is there an equivalent for Windows Phone 8?
If you are developing a Universal WinRT Windows Phone application, you could use the Windows.ApplicationModel.Email.EmailMessage
namespace as the Microsoft.Phone.Tasks.EmailComposeTask
namespace doesn't work on WinRT application.
Then, uses this code to create and launch a new email.
// Create your new email message.
var em = new EmailMessage() ;
// Add as much EmailRecipient in it as you need using the following method.
em.To.Add(new EmailRecipient("yourname@yourdomain.com"));
em.Subject = "Your Subject...";
em.Body = "Your email body...";
// You can add an attachment that way.
//em.Attachments.Add(new EmailAttachment(...);
// Show the email composer.
await EmailManager.ShowComposeNewEmailAsync(em);
