"De Icaza noted that what the Mono project has been doing is to
actually identify what parts of .NET developers are using. Since
the Mono 1.2.3 release the MoMA (Mono Migration Analyzer) tool has
been available to examine existing .NET executables and determine
all of the items that are necessary from .net in order to run.
"Thanks to statistical data from MoMA, we're able to prioritize
what people are actually using," De Icaza said. "What is important
about this is there are some API's that we've definitely postponed.
For example, [Windows Presentation Foundation] is not something
that we're working on right now."
