Description

I'm experiencing the following errors when attempting to build the [general\toaster\toastDrv](https://github.com/microsoft/Windows-driver-samples/tree/main/general/toaster/toastDrv) KMDF projects with Visual Studio 2022:

It would be great if your could fix these errors so that the samples build out-of-the-box. Alternatively, clearly document how to rename the services. The reason for asking is that it's unclear to me if it's sufficient to change the service name, or if the SYS and INX/INF files also need to be renamed.
