How to write to HttpContext.Response.Body on .NET Core 3.1.x

Question

I've been trying to write or set the HttpContext.Response.Body but to no avail. Most of the samples I found is using the Body.WriteAsync but the paramaters are different then the example. I tried converting my string to byte[] but the text doesn't show on my Response.Body.

You can refer to the following code, which works well for me.

public async Task<IActionResult> Test()
{

    //for testing purpose
    var bytes = Encoding.UTF8.GetBytes("Hello World");

    await HttpContext.Response.Body.WriteAsync(bytes, 0, bytes.Length);

    //...

Besides, you can call HttpResponseWritingExtensions.WriteAsync method to write the given text to the response body.

public async Task<IActionResult> Test()
{
    //for testing purpose
    await Microsoft.AspNetCore.Http.HttpResponseWritingExtensions.WriteAsync(HttpContext.Response, "Hello World");

    //...
