Can HttpClient's reponse Content be null?

Question

When getting a HttpResponseMessage from HttpClient, are there any cases where its Content may be null?

HttpClient client = new HttpClient();
HttpResponseMessage response = await client.GetAsync("https://www.stackoverflow.com/");
if (response.Content == null) {
    // Can this happen?
}
else
{
    string responseBody = await response.Content.ReadAsStringAsync();
    // ...
}

If you think it can be null, please provide an example to reproduce it.

I have tried many things, but without being able to get null:

So as MSDN says, yes it can be null, but you should use EnsureSuccessStatusCode to check response valid or not
