Hi, i use version 1.7.27 of Hangfire in a .net 4.8 application deployed as windows service.  
I’ve noticed that in worker logs i’ve a huge amount of this:

_2023-11-08 22:34:10,807 [Worker #2] INFO Hangfire.SqlServer.SqlServerObjectsInstaller - Start installing Hangfire SQL objects…_  
_2023-11-08 22:34:11,776 [Worker #2] INFO Hangfire.SqlServer.SqlServerObjectsInstaller - Hangfire SQL objects installed._  
_2023-11-08 22:34:11,947 [Worker #2] INFO Hangfire.SqlServer.SqlServerObjectsInstaller - Start installing Hangfire SQL objects…_  
_2023-11-08 22:34:11,963 [Worker #2] INFO Hangfire.SqlServer.SqlServerObjectsInstaller - Hangfire SQL objects installed._  
_2023-11-08 22:34:12,088 [Worker #2] INFO Hangfire.SqlServer.SqlServerObjectsInstaller - Start installing Hangfire SQL objects…_  
_2023-11-08 22:34:12,119 [Worker #2] INFO Hangfire.SqlServer.SqlServerObjectsInstaller - Hangfire SQL objects installed._

Hangfire works correctly, in sql database i’ve version 5 as schema.  
What can be the cause? How can i avoid this?

Thanks
