I can't reproduce this with the latest version from wrench (mtouch (9b3a855)) - can you retest?
Comment 3 Sebastien Pouliot 2013-07-02 19:38:09 UTC
An out-of-band (no F# involved ;-) test seems to indicate the offending symbol is not part of the latest builds.

$ strings /Developer/MonoTouch/usr/lib/mono/2.1/FSharp.Core.dll | grep Reflection
$ strings /Developer/MonoTouch/usr/lib/mono/2.1/FSharp.Core.dll | grep Emit

Closing. Looking forward to the VERIFIED status.

We have checked this issue on :

All mac
XS 4.0.10(build 7)
Mono 3.1.2
Xcode 4.6.2

We installed F# language binding & F# support for X.Android and X.iOS mobile development successfully in Add in manager. We observed that no build errors are shown on creating and building F# template project for iOS and Android. Hence updating the issue status as Verified fixed.
