The "xamlCTask" task has been declared or used incorrectly

The "XamlCTask" task could not be instantiated from "C:\"MyPath"\Documents\Visual Studio 2013\Projects\XamarinClients\packages\Xamarin.Forms.2.0.0.6490\build\portable-win+net45+wp80+win81+wpa81+MonoAndroid10+MonoTouch10+Xamarin.iOS10\Xamarin.Forms.Build.Tasks.dll". Could not load file or assembly 'Xamarin.Forms.Build.Tasks, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Invalid pointer (Exception from HRESULT: 0x80004003 (E_POINTER)) XamarinClients.Droid

I get the same message for IOS and Android.

I think its after todays update to the stable version. Any idea of how to fix this?
