Launch the compose email dialog

Create a new EmailMessage object and set the data that you want to be pre-populated in the compose email dialog. Call ShowComposeNewEmailAsync to show the dialog.

private async Task ComposeEmail(Windows.ApplicationModel.Contacts.Contact recipient,
    string subject, string messageBody)
    var emailMessage = new Windows.ApplicationModel.Email.EmailMessage();
    emailMessage.Body = messageBody;

    var email = recipient.Emails.FirstOrDefault<Windows.ApplicationModel.Contacts.ContactEmail>();
    if (email != null)
        var emailRecipient = new Windows.ApplicationModel.Email.EmailRecipient(email.Address);
        emailMessage.Subject = subject;

    await Windows.ApplicationModel.Email.EmailManager.ShowComposeNewEmailAsync(emailMessage);


Attachments that you add to an email by using the EmailAttachment class will appear only in the Mail app. If users have any other mail program configured as their default mail program, the compose window will appear without the attachment. This is a known issue.
