[MonoDevelop] Fwd: Several references could not be found

[pinggi at centrum.cz]

1. I installed mono-2.10.4-gtksharp-2.12.11-win32-0.exe.2. I wanted to install MonoDevelop-2.6.rc1.msi but it said that I don't have gtksharp > 2.12.9 installed. I didn't understand because I installed gtksharp-2.12.11 within mono-2.10.4-gtksharp-2.12.11-win32-0.exe or not? Well, I didn't mind.
3. I installed gtk-sharp-2.12.10.win32.msi and then MonoDevelop-2.6.rc1.msi worked without error.
4. Run Monodevelop
5. Loaded my C# GTK application and compiled it - everything went well.
6. Changed "Default Runtime (MS.Net 4.0)" to "Mono 2.10.4" and compiled it. I got several errors that gtk cannot be found and references "atk-sharp",  "gdk-sharp", "glade-sharp",  "glib-sharp",  "gtk-sharp",  "pango-sharp" became red.
7. Don't understand why and how I can fix it.
 
Can you help me please?
