License key management

Question

I developed the application in C #, and now I'm in the licensing process. What should I do with the license key after I register my application with it on the Internet on my servers? Where should I store it? Should I check the application every time I start?

Answer 1

Basically you have three options:

• Store license keys in the database, provide a web service and check the application for it every time you start (the disadvantage is that you need to support authentication servers and provide a very good time or you will have dissatisfied clients)
