      Application started. Press Ctrl+C to shut down.

I don't want to use Ctrl + C to shut down the application

Answer 1

You can run your task in background, either by following the documentation, but I simply prefer using & after your program name, it will be executed in the background (if linux), and here you have the solution for windows

dotnet core run &

Because it is in the background it is harder to interrupt, you have to find the pid (linux, mac os) or open control task manager (windows)

Answer 2

You can use IWebHost.RunAsync() method. This version does not wait for CTRL+C

An example:

var host = new WebHostBuilder() 
.UseKestrel(opt => {  })
.UseStartup<Startup>()
.Build();

CancellationTokenSource cts = new CancellationTokenSource();
await host.RunAsync(cts.Token);

On the output you will not see anymore the message "Application started. Press Ctrl+C to shut down.". When you press CTRL+C it will be routed to the main thread from the input pipe as usual.
