Resolving HttpContent ReadAsAsync<T> returning null in asp.net core

The HttpContent extension ReadAsAsync<T> is very practical since it will allow you to deserialize an incoming response to a typed object. When using the HttpClient in asp.net core the method will fail to perform the deserialization unless you set the mediaType in the accept headers, in example

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 

A complete example would look like this

using (HttpClient client = new HttpClient())
{
    var json = new StringContent(content: jsonString, encoding: Encoding.UTF32)
    {
        Headers =
        {
            // required for json apis
            ContentType = new MediaTypeHeaderValue(mediaType: "application/json")
        }
    };

    // required to use ReadAsAsync
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 

    using (var res = await client.PostAsync(requestUri: $"{apiUrl}", content: json))
    {
        using(HttpContent content = res.Content)
        {
            var typedData = await content.ReadAsAsync();
        }
    }
}

Cheers
