Description Radu 2014-05-22 07:55:37 UTC
Making a reference to any predefined NSColor object (like NSColor.Black) seems to trigger loading of the fonts.conf file from from /Library/Frameworks/Mono.framework/Versions/Current/etc. When running the packaged product on a machine which doesn't have mono  installed (and of corse none of the Xamarin related software and platorms) the following line is spit on the console when it hits the first line referencing a predefined static color from NCColor:
Fontconfig error: Cannot load default config file

After the message, the process consumes a lot of cpu power for a while (even up to a minute on some machines) then the app continues to work normally and any further references to static predefined colors in NSColor don't block the running thread anymore.

To test this just make a very simple mac project and reference NSColor.Black (or whatever color you want) from a variable, then compile and try to run on a mac without mono on it (or temporarily move the fonts.conf file to some other location so you can actually debug this).

Please excuse my haste in writing the description, I made a big mistake:
Any NSColor must be read as "Color" from the System.Drawing namespace

I beleive this bug is a duplicate of bug 17225 and bug 20210.
