Monodevelop gtk-sharp 3.0

Question 1

since I'm trying to get gstreamer-sharp 0.99 to run with my application, I heard, that gtk-3 is needed for gstreamer.

gstreamer-sharp 0.99 doesn't depend on gtk-sharp 3, it depends on glib-sharp 3, which, as of today, is hosted in the same repo as gtk-sharp 3, but that will change soonish.

Has anybody tried to build gtk-sharp 3.0 for monodevelop?

MonoDevelop only works with gtk+ 2.x versions. If you install gtk-sharp 3, you will not break or override gtk-sharp 2.x, as they can be installed in parallel.

I'm running fedora and tried, but all I could do, is link the dll manually to my project and the application didn't start.

Tried...? And what...? What happened? I'm assuming you failed? How did you fail, what error did you get?

Is gtk-sharp still beta?

gtk# 3 yes, gtk# 2.x is very mature though.

Question 2

Currently is possible to use gtk-sharp3 in MonoDevelop (at least in Linux). In Linux Mint 17 Quiana is necessary to install gtk-sharp3 package (no need to build) and add (in extension manager, install from file button) to MonoDevelop MonoDevelop GTK#3 Project Template extension.

This requires a MonoDevelop version >= 5 (see extension addin.xml file) - based on Xamarin packages (again, in my system). Installation guide for debian based systems.

GUI must be edited in an external program, Glade (a glade package) - see Gtk#3 project template descriprion.

Maybe required step is use the latest Mono release (see this) and probably required step is install Gtk3 first (libgtk-3-dev package and his dependencies). I have installed Gtk2 and Gtk3 as well as gtk-sharp2 and gtk-sharp3 simultaneously.

After creating GTK#3.0 project using template is (for my) necessarily add reference to gio-sharp v3.0 and regenerate MainWindow.ui with the use glade!

I hope that's all!
