Getting License exception while starting application after upgrading from evaluation version to license version
Remove the Eval version key from the License Manager which is available at Start--> All Programs --> Syncfusion --> Essential Studio 220.127.116.11 --> Utilities --> License Manger.
Now delete the output folders of the project(the bin and the obj folders).
Open the Assembly Manager from Start--> All Programs --> Syncfusion --> Essential Studio 18.104.22.168 --> Utilities --> Assembly Manger. Select ''Remove All Versions'' and then click ''Perform Action''.
Once all the assemblies are removed. Select the ''Install Version 22.214.171.124'' in the Assembly Manager and then click ''Perform Action''. This will install the Syncfusion assemblies in the machine and configure that for the latest version.
Now the machine is configured for the licensed version.
