Syncfusion Unlock Key

You applied the unlock key but did not regenerate the runtime license file for your project. Or, you have a leftover SyncfusionLicense.txt from the trial. Fix: Delete any existing license files from your project. Reopen the Syncfusion License Manager, re-enter your unlock key, and generate a fresh license file. Rebuild the solution.
