[Gtk-sharp-list] How can I use CSS styling in my GTK# application?

[don-prog]

After install Gtk# 2.99.3 using the .msi installer I got these changes and
some issues:
1. Now I can use the CssProvider class.
2. I needed to connect gio-sharp due to an error: *The type
"GLib.Application" is defined in an assembly that is not referenced. You
must add a reference to assembly "gio-sharp, Version=3.0.0.0,
Culture=neutral, PublicKeyToken=35e10195dab3c99f" (CS0012)*
3. I got next warning: *Found conflicts between different versions of same
dependent assembly (MSB3247)*
4. I got next exception:* System.MissingMethodException: "Void
System.Runtime.InteropServices.Marshal.StructureToPtr(!!0, IntPtr, Boolean)"
*
How I can resolve these issues?
Thanks!
