I am developing a helper CRM solution and want to upload it to Microsoft Appsource. I want to apply licensing for it, please tell me some instructions or links to any article introduce about how to do this.
Possible strategy:
License contains "valid until" date (encrypted)
Unique name of the CRM organization must be encoded in the license and checked in the solution, so that the license cannot be used in other environments (only in the one with the right organization).
Validity date is checked every time the solution is used
License must be encrypted/signed, so that it cannot be tweaked.
