For the development of a Ract component I used MUI Autocomplete. I got the array of objects from SharePoint list and used this data as a parameter for options. Actually, you can use any source.
But I had a lot of warnings in console.

None of the options match with {"Id":0,"Title":"","ProjectDescription":"","AvailableObjects":[]}.
You can use the isOptionEqualToValue prop to customize the equality test.

An application that was developed by me as a service with Net Core 8 didn’t want to start working as a Windows service. The application was created in Visual studio 2022 with a “Worker service” template. If you just start the app, it works. But I had problems to start it as a Windows Service.
