The reason is simply ProjectType - VS does not understand MonoTouch 
Project type actually it's GUID
see: Using a monotouch project in Visual Studio 2008/2010
(This is what our guys have implemented with batch script and we are 
currently in the early
test phase....)

There are few comments about this post:
"7zip does not extract files deeper than 
The fact is that unzipping must be done twice in order to get what You need!
Remember with all this modern stuff (xap, apk, pkg) if You're stuck try 
renaming it
to zip and unzipping it - it may be hidden/renamed zip archive. It 
usually works for us.
::echo off

set MONOTOUCH_PKG=monotouch-eval-4.2.2.pkg
set PATH_DESTINATION=C:\bin\iOS\MonoTouch\

set PACKER_7ZIP="%ProgramFiles%\7-zip\7z.exe"
::set PACKER_7ZIP=c\bin\7za.exe"
::set PACKER_7ZIP=c:\bin\bzip2-105-x86-win32.exe
:: c:\bin\bzip2-105-x86-win32.exe --decompress %MONOTOUCH_PKG%.zip

echo unpacking %MONOTOUCH_PKG%
echo        to %MONOTOUCH_UNPACKED%


echo f | xcopy /q /y /i %MONOTOUCH_PKG% %MONOTOUCH_PKG%.zip

cd %MONOTOUCH_UNPACKED%\monotouch.pkg
dir Payload
echo f | xcopy /q /y /i Payload Payload.zip
%PACKER_7ZIP% x Payload.zip -oPayload.unpacked

cd Payload.unpacked
move Payload Payload.zip
%PACKER_7ZIP% x Payload.zip -oPayload.unpacked


If You want I can ask our mac freak how far is he with this stuff!

We have managed to create Visual Studio Solution multi-Project template 
that creates
WP, M4A, SL, WPF, WF and asp.net solution with one duobule-click in VS. 
Right now
we are on the mac side trying to add MonoTouch in the template.
But for that we'll need small batch script with moving files (project 
files for MT) and
a bit of playing with sed (yes we have it on windows.... 8-P.

The script will be used for converting MT files to VS actually 
commenting it out when
comming from Mac world to Windoze and uncommenting project type in 
csproj file:

Doing it reverse when pushing back to mac...

There are 2 or 3 apps that do that, but we are aiming for batch cos we 
are lazy! Clicking in UI
