Purified version using of gwenzek's formatter employing async/await:

public class PlainTextFormatter : MediaTypeFormatter
{
    public PlainTextFormatter()
    {
        SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/plain"));
    }

    public override bool CanReadType(Type type) =>
        type == typeof(string);

    public override bool CanWriteType(Type type) =>
        type == typeof(string);

    public override async Task
