Description
When an exception occures in IHostedService without calling await, it is not logged to the ILogger.
This make it difficult to identify the reason for the application shutdown when writing logs to an external service.
Reproduction Steps
IHost host = Host.CreateDefaultBuilder(args)
.ConfigureServices(services =>
{
services.AddHostedService<Worker>();
})
.Build();
await host.RunAsync();
public class Worker : IHostedService
{
public Task StartAsync(CancellationToken cancellationToken) =>
throw new Exception();
public Task StopAsync(CancellationToken cancellationToken) =>
Task.CompletedTask;
}Expected behavior
When an exception occurs within the StartAsync of IHostedService, whether or not method has await, the exception should be logged to the ILogger
Actual behavior
When an exception occurs in the StartAsync without calling await, the exception is not logged to the ILogger
Regression?

Known Workarounds
No response
Configuration
Sdk: Microsoft.NET.Sdk.Worker
Framework: .NET 7.0.3
Other information
It is also lead to misunderstanding of BackgroundServiceExceptionBehavior.Ignore, which continue to stop host when exception occurs.
This can be relative to #67146
