This is using Version 1 Azure functions (version 2 and 3 are similar):

using System.Net;
using System.Net.Http;

....

[FunctionName("MyFunction")]    
public static async Task<HttpResponseMessage> Run([HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)]HttpRequestMessage req, TraceWriter log)
{    
    return new GetHtmlResponseContent("<html><body>Hello <b>world</b></body></html>"};
}

private static HttpResponseMessage GetHtmlResponseContent(string msg, HttpStatusCode httpStatusCode)
{
    var response = new HttpResponseMessage(httpStatusCode);
    response.Content = new StringContent(msg));
    response.Content.Headers.ContentType = new MediaTypeHeaderValue("text/html");

    return response;
}

You might want to return a JSON payload containing your return value(s).
