Description Alex 2015-07-20 03:46:55 UTC
I tried to use Mono 4.0 runtime on Windows 8.1. My app contains NancyFx (https://github.com/NancyFx/Nancy), a framework for building REST services. When I run my test app on windows with nancy self-hosting and MS .Net framework, it works really good. But, when executed with mono (on windows also), it lacks performance and gives me a little strange responses.

For example, for a simple method like below:

Get["/IsActive"] = param =>
                var json = Response.AsJson(true);
                return json;
I get simply true in .net execution and

P/1.1 200 OK
Content-Type: application/json; charset=utf-8
Server: Mono-HTTPAPI/1.0
Date: Mon, 13 Jul 2015 18:05:24 GMT
Transfer-Encoding: chunked
Keep-Alive: timeout=15,max=100

and on mono I get this response really slow. I guess it's some mono issues with HttpHandler or something...

To reproduce this bug simply create Nancy self-hosted app with the registration below (you can find examples on Nancy github page) and try to consume it.

Please provide self contained repro for your issue

This was already reported in Bug 30065.  That bug has an attached solution that shows the problem.
Comment 3 Seth Wenzel 2015-07-26 15:03:22 UTC
Also, we see this with both Nancy and WebAPI.  Bug 30065 reproduced it by using OWIN middleware without a framework like WebAPI or Nancy.

Is there any update?

I left a comment on BUG 30065 as well and I can post another self-contained reproduction if requested.

Is there any news about this problem? I'm using mono x64 and there the problem still exists
