QuestionSerial Keys. Make trial version. Examples ? Pin

Hi. Can anyone help me with understanding how to make a trial version of a program, e.g. it works for 10 days and then refuses to work, until user enters a serial key.
Is there an article about how to do that with examples in c# ? By "Examples" i mean pieces of code where the whole mechanism is written. E.g. how to generate keys. How to disalow user to use program for more than 10 days by simply reinstalling it ?


Thanks in advance
