title: How to use StorageItem to save vsto add-in specific data
body: <p>I am developing a VSTO add-in for Outlook in C#. I would want to be able to save some add-in specific data, which is a complex user defined type. I have gone through the MSDN documentaion of <a href="https://msdn.microsoft.com/en-us/library/microsoft.office.interop.outlook.storageitem.aspx" rel="nofollow">StorageItem</a> API, but doesn't help much. Is using the StorageItem the right approach? Any code samples would help.</p>
