Using EASendMail SMTP Windows 8/10 Runtime Component in Windows Store Apps

Add Reference of EASendMail to Visual Stuido 2012 or later Project

To use EASendMail SMTP Component in your Windows Store App project, the first step is "Add reference of EASendMail to your project". Please create/open your project with Visual Studio.NET, then choose menu->"Project"->"Add Reference"->".NET"->"Browse...", and choose the "Installation Path\Lib\[portable* or uap]\EASendMail.winmd" from your disk, click "Open"->"OK", the reference of EASendMail will be added to your project, and you can start to use EASendMail SMTP Component in your project.

Deploying EASendMail with Application

After compiling your project, a copy of EASendMail.winmd will be generated by compiler in same folder of your application executable file. Packing all the *.winmd, *.dll and *.exe in the folder to installer is ok. As EASendMail.winmd is a pure Windows 8 Runtime Component, it doesn't require "Regsvr32" (self-register) to register the dll.

File	.NET Framework Version
Lib\uap10.0\EASendMail.winmd	Built with Universal Windows Platform. It requires Windows 10 or later version (Universal Windows Platform).

Mail Address Syntax

For single email address (From), the syntax can be ["][display name]["]<email address>.
For example, "Tester, T" <test@adminsystem.com>, Tester <test@adminsystem.com>, <test@adminsystem.com> or test@adminsystem.com.

For mulitple email address (To, CC, Bcc), the syntax can be [single email],[single email]... (,;\r\n) can be used to separate multiple email addresses.
For example: "Tester, T" <test1@adminsystem.com>, Tester2 <test2@adminsystem.com>, <test3@adminsystem.com>, test4@adminsystem.com

Server Address Syntax

The server syntax is [server ip or domain] [port]. SPACE is used to separate server address and port. If port is not specified, default port 25 will be used.
For example: localhost 25 or localhost.
