I have SDK 6.1 and 7.1 installed on the mac, if I select 6.1 in Xamarin studio/build run on the mac with the 7.1 sim I get the 6.1 look on buttons etc which is of course correct since I used the 6.1 sdk, if I select 7.1 I get the 7.1 look and feel, again correct.
...but...if I use VS and do the same I always get 7.1, i.e. transparent buttons and overwrite the battery area.
It appears VS is not using the selected SDK
