Microsft Exchange ActiveSync(EAS) framework in .Net
<h3>
ActiveSync is an open-source framework to synchronize ActiveSync compatible devices such as mobile phones (Android, iOS, Windows Phone, Symbian), tablets, Outlook, etc. </h3>

<p>I wrote it from scratch and I hope it would be the primary and robust implementation of ActiveSync protocol in .Net. You can checkout Microsoft EAS(Exchange ActiveSync) command reference protocol <a href="https://docs.microsoft.com/en-us/openspecs/exchange_server_protocols/ms-ascmd/1a3490f1-afe1-418a-aa92-6f630036d65a"> here.</a> It was my primary references to implement this framework.

About 5 years ago, I had a project to synchronize an office automation system with mobile. The requirement was that users want to access their contacts and inboxes in mobile. </p>
<p>We did not want to implement multiple apps for different types of mobile platforms like Android, iOS, Windows Phone, etc. Therefore, we started to research and finally, we decided to implement a standard protocol to support synchronization of items in any device.</p>
<p>I started to learn about Microsoft ActiveSync protocol. This protocol is used in Microsoft Exchange too. At that time, there were no library in .net and I had to implement it from scratch. I try to design a framework to support ActiveSync in .Net and it can be use in anywhere you need!</p>
<p>
You can easily have your own implementation of ActiveSync. Just implement these services:
<UL>
<li><b>IAuthenticationService:</b> To authenticate users
<ul>
<li>Authenticate</li>
</ul>
</li>
<li><b>IFolderService:</b> To support synchronization of folders
<ul>
<li>CreateFolder</li>
<li>UpdateFolder</li>
<li>DeleteFolder</li>
<li>GetFolder</li>
<li>GetAllFolders</li>
<li>EmptyFolderContents</li>
</ul>
</li>
<li><b>IContactService:</b> To support synchronization of contacts
<ul>
<li>GetContacts</li>
<li>FetchContact</li>
<li>UpdateContact</li>
<li>AddContact</li>
<li>DeleteContact</li>
</ul>
</li>
<li><b>IEmailService:</b> To support synchronization of emails (or messages in your domain)
<ul>
<li>SendMail</li>
<li>GetEmails</li>
<li>ReadMail</li>
<li>UnReadMail</li>
<li>EditMail</li>
<li>ReplyEmail</li>
<li>ForwardEmail</li>
<li>FetchEmail</li>
<li>MoveConversation</li>
</ul>
</li>
</UL>
</p>

Now I am creating a new version of ActiveSync in .Net Core and I appreciate any contribution to develop this framework.
