c# - Wait for n seconds, then next line of code without freezing form

Question

Hi I am trying to find a method of waiting a number of milliseconds before moving to the next line of code,

I have looked into Thread.Sleep but this will freeze the main form, I would like this to remain active.

I tried timers and stopwatches and both freeze the main form when they should be posting to a console when they tick.

I couldn't find a way of using task.delay or background worker in the wait I wanted either.

Pseudo Code:

Wait 2 - 6 seconds
Log "waiting"
Log "waiting"
Log "waiting"
Stop Waiting - Run next line of code.

The methods I have tried just freeze up the form and fill the log afterwards, I just want a simple method of waiting without freezing the form and without having to deal with events being called which would mean the next line isn't run.

Any help would be awesome because I am still new to c# and its been driving me a bit mad :(

The await keyword, in conjunction with Task.Delay makes this trivial.

public async Task Foo()
{
    await Task.Delay(2000);
    txtConsole.AppendText("Waiting...");
    DoStuff();
}
