Okay, I don't know what the issue with the mailing-lists is then :-(

Okay, so sometimes the .h files are generated and sometimes not.

I guess that answers the question I wanted to know from the Chris's... this
suggests that at least in your case, you have C# classes that MonoDevelop
should be exporting as ObjC .m/.h files.

What is probably happening is that MonoDevelop's Type database for your
project is incomplete and/or corrupt somehow.

If this happens again, try closing MonoDevelop, deleting all the *.pidb
files in your project, and then reopening your project in MonoDevelop to
allow it to regenerate them.

Simpler than trying to paste everything into a new project :-)


In the meantime, hopefully we can figure out what the problem is with the
Types database (I wonder if Mike's new parser in the newresolver branch
fixes this?)

I wrote some fixes to MonoDevelop's code that syncs files back from Xcode
in cases where new files were added in Xcode which are in the upcoming
2.8.8 Stable release. Essentially what I did was to prevent back-and-forth
syncing with Xcode when importing the new files.

In 2.8.6.x, when a new file is imported from Xcode, it causes a re-sync
back out to Xcode, and then another re-sync back from Xcode. All of this
extra AppleScript chatter might be too much for Xcode to handle (Xcode
seems rather fragile with AppleScript requests), not to mention just makes
the whole process less efficient. MonoDevelop 2.8.8 should definitely sync
files back from Xcode faster in cases where new files were added in Xcode.

With any luck, 2.8.8 final should be released to the stable channels by
next week sometime.
