Screenshot of crash in simulator.

I'm getting a DllNotFoundException when running my app in the simulator. I
upgraded to OS X Lion, upgraded Xcode 4.1 for Lion and now I'm getting this
exception. I noticed that if I make a copy of the iPhoneSimulator4.3.sdk folder
/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk
then rename it to iPhoneSimulator3.2.sdk it will work.

Comment 1 Chris Toshok 2011-07-25 22:51:29 EDT
Interesting.  Is the project configured to be using the 3.2 sdk?  It's in
"$solution options" -> iPhone Build -> SDK version.
Comment 2 Andrew Young 2011-07-26 00:19:14 EDT
No. It is set to Default. The only other option in that field is 4.3.
Comment 3 Chris Toshok 2011-07-26 12:16:57 EDT
Ahh, found the issue.  I'll get a fix in git soon.
Comment 4 Andrew Young 2011-07-27 13:00:44 EDT
Awesome. Thanks. As a short term work around, renaming the folder should be ok
right?

Comment 5 Chris Toshok 2011-07-27 22:02:33 EDT
Yeah, in a way that's essentially what the fix is, except wr arrive at it by
using the 4.3 directory while you rename 4.3 to 3.2.
Comment 6 Chris Toshok 2011-08-04 17:11:11 EDT
Sorry about not giving you more feedback - the fix is in git (as of July 26)
and will go out with the next release of monotouch.
Comment 7 Andrew Young 2011-08-04 17:13:38 EDT
Thanks. Any timeline on when the next release will be? There's a few bug fixes,
including this one, that we're waiting on in the next release.
