If you're using .NET 6, you can use the new DateOnly type:
DateOnly Struct (System) | Microsoft Docs[^]
C#
[HttpGet]
public IActionResult justdate()
{
    var date = DateOnly.FromDateTime(DateTime.Today);
    return Ok(date);
}

That code won't even compile, much less generate a run time error:
C#
var date = DateTime.Now.Date.ToShortDateString;
Will give you an error:
Cannot assign method group to an implicitly-typed variable
You need to start by correcting that - add the brackets to call the method:
C#
var date = DateTime.Now.Date.ToShortDateString();

Now your code will maybe compile - and you won't be running the old version of the code ...
