C#, Outlook Web-Add In

Question

I'm creating my first C#, Outlook Web-Add In, in Visual Studios and wondering if someone have any links to more information and tips than Microsoft's resources?
I planning to create a app so it possible to create a task pane where you can drag and drop e-mails from for example the inbox to save them to an API. While also getting existing e-mails from that API and show them in the task pane.
