IsLicenseGenuine static method
It verifies whether your app is genuinely activated or not. Returns LexStatusCodes LA_OK, LA_EXPIRED, LA_SUSPENDED, LA_GRACE_PERIOD_OVER, and LA_FAIL.
The verification is done locally by verifying the cryptographic digital signature fetched at the time of activation. After verifying locally, it schedules a server check in a separate thread. After the first server sync it periodically does further syncs at a frequency set for the license.
In case server sync fails due to network error, and it continues to fail for fixed number of days (grace period), the function returns LA_GRACE_PERIOD_OVER instead of LA_OK. This function must be called on every start of your program to verify the activation of your app.
Note: If application was activated offline using ActivateLicenseOffline() function, you may want to set grace period to 0 to ignore grace period.
The function throws a LexActivatorException on error.
