MonkeySpace Talk Slides and Notes

I delivered my first conference talk at MonkeySpace yesterday. The video will be available at some point, but in the meantime, here are the slides and some notes to help make sense of them.


Mono is a potentially attractive option for organizations that are already using ASP.NET because IIS is a pain to configure and Windows licenses can get really expensive.

Many libraries indicate that they support Mono, but there is little information about using it for web sites and services beyond basic, “getting started” tutorials. I’m trying to document and publish my experiments as I go along to help others who might be trying this and in the hope that more people will start documenting their experiences, too.

The major snags I encountered were: * xbuild doesn’t have a good fallback mechanism for unkown profiles (we use the Client Profile for some assemblies) * Microsoft’s format for Forms Authentication cookies is undocumented and difficult to reverse engineer. (see my earlier post on this topic) * Mono’s support for SQL Server hasn’t received significant updates for 2008 and 2012. * New Relic—an awesome monitoring service we use—doesn’t support Mono.

I worked around all of these issues and even built my own version of the New Relic Profiler (linked below). In testing a simple service, I encountered very inconsistent performance that was quite sensitive to GC pauses.

There was a period of about seven minutes during which the performance of the Mono version of the service was as good as—or better than—its Windows counterpart, so I plan to continue investigating. These are some initial areas I intend to look into:
