The Gtk# website can be found at: http://www.mono-project.com/GtkSharp

Gtk# is a .NET language binding for the GTK+ toolkit and assorted GNOME libraries. Gtk# is free software, licensed under the GNU LGPL.

Building & Installing Gtk#:

Join the chat at https://gitter.im/GLibSharp/GtkSharp

Install the gtk-3 development headers first. On Debian, this can be done using:
apt-get install libgtk-3-dev

We are using [meson](http://mesonbuild.com/) as a build system, you can build with

    meson build/
    ninja -C build/

The gui-thread-check profiler module.

Since version 3 of gtk# a profiler called "gui-thread-check" is included as
part of the install for debugging purposes. (It's located in the subfolder
gtk/gui-thread-check .)

This profiler module can be used to check if a GTK# application is trying to
invoke gtk or gdk methods from a thread which is not the main GUI thread.

To use it, run your application with the command:

    mono --profile=gui-thread-check yourapp.exe

If the profiler is properly installed, you'll see an output like this:

    *** Running with gui-thread-check ***
    *** GUI THREAD INITIALIZED: 2861676352

While the application is running, if the profiler detects a non-gui thread
invoking gtk methods, it will print a warning message together with a
stack trace. For example:

    *** GTK CALL NOT IN GUI THREAD: Widget.gtk_widget_get_parent
