UseWindowsService() - The process was terminated due to an unhandled exception.

I started a gRPC project from Visual Studio 2022 with .Net 6.0.

Steps:

1. Microsoft.Extensions.Hosting.WindowsServices (6.0.0)
2. Add this line to program.cs builder.Host.UseWindowsService();
3. Build the project
4. Created a Window Service with the sc command:

sc create "Grpc Test2" binPath= C:\Users\WuJ22\source\repos\GrpcService1\GrpcService1\bin\Release\net6.0\GrpcService1.exe start= auto DisplayName= "Grpc Test2"

Please provide a succinct description of your issue.

1. The service failed to start
2. Event log has this message:

Application: GrpcService1.exe
CoreCLR Version: 6.0.622.26707
.NET Version: 6.0.6
Description: The process was terminated due to an unhandled exception.
Exception Info: System.NotSupportedException: The content root changed from "C:\Windows\system32" to "C:\Users\WuJ22\source\repos\GrpcService1\GrpcService1\bin\Release\net6.0". Changing the host configuration using WebApplicationBuilder.Host is not supported. Use WebApplication.CreateBuilder(WebApplicationOptions) instead.

at Program.

$(String[] args) in C:\Users\WuJ22\source\repos\GrpcService1\GrpcService1\Program.cs:line 9

Expected behavior

1. Service to start without error

Actual behavior

2. Service wouldn't start

None at the moment

Start with the referenced Program.cs line 9 and the UseWindowsService call in a .NET 6 gRPC project. Reproduce the service startup using the sc command and inspect the hosting configuration exception and related Windows service hosting behavior. Done means the service starts without the reported unhandled exception, with a regression test or documented reproduction if the project supports it.
