Hi,

What is the situation with OpenRasta on Mono? Is it supported? I'm
trying to run a simple application with xsp on Mono 2.10.6, but I'm
getting an ObjectDisposedException. The same code runs fine under .NET
on Windows.

I tried to compile OpenRasta myself under Mono, but OpenWrap wasn't
working for me either.

I can provide details on errors if you want them, otherwise I'll just
have to stick to Windows.

If you can provide some details about the ObjectDisposedException that'd be great. Hosting on HttpListener works on mono (apparently since 2.10) but under xsp it's untested.

I've seen that exception on windows too in my tests actually. The tests keep starting and stopping the host and hitting it with watin tests. it happens very rarely on the build server. Probably a race condition and might be unrelated but thought I'd mention it anyway

Sorry about the formatting on that, I pasted that in in a rush this morning.

To be clear, when I serve my app with xsp, any request to it gets a 500 response with the following stack trace:

Is this more likely to be a bug in Mono than the OR code?
