Have you looked at the [`Settings`](http://msdn.microsoft.com/en-us/library/aa730869.aspx) file? – Oded Apr 23 '13 at 18:25

You can use XML to store last data, then restore from that XML file. – Javidan Apr 23 '13 at 18:25

You can put all the important data in a state class, and then serialize it to file in a binary, XML or JSON format. When your application is restarted, you can deserialize this file back to a class instance and use it.
For binary serialization look at BinaryFormatter, for XML - XmlSerializer, for JSON you can user JSON.Net
You may also need some plumbing code to rebuild caches, resubscribe to events, e.t.c.
