How to print process name in StartUp.cs for .net core 3.1

Question

From yesterday I have started learning .netcore . I have installed .netcore 2.2 & .netcore 3.1 in my machine.

In .netcore 2.2 , I am able to print the process name on the website. ie I had written this below code in Startup.cs in an empty .netcore web application:

app.Run(async (context) =>
{
    await context.Response
    .WriteAsync(System.Diagnostics.Process.GetCurrentProcess().ProcessName);
});

But now in .netcore 3.1 , by default, it is calling the razor pages. So, I tried to replace that code with the above code, but I am getting this below error:

'HttpResponse' does not contain a definition for 'WriteAsync' and no accessible extension method 'WriteAsync' accepting a first argument of type 'HttpResponse' could be found (are you missing a using directive or an assembly reference?

It seems the extension method ' WriteAsync ' has been removed in .netcore 3.1 .

So, how do I display that now?
