Played here also with gtk3, but at least it did not start.

I have installed gtksharp using this guide:

https://github.com/GtkSharp/GtkSharp/wiki/Installing-Gtk-on-Windows

I also tried starting it with msys2

I also installed then
https://github.com/tschoonj/GTK-for-Windows-Runtime-Environment-Installer

but this did not solve the error

I think it uses gtksharp2 installation from this line:

https://github.com/MakiWolf/dotdevelop/blob/7dc1f75236d71b4a995caed84fee7b192be126b9/main/src/core/MonoDevelop.Core/MonoDevelop.Core/Platform.cs#L102

I also don't know if gtksharp have a registry path to replace gtk2 here?

Also tried to use original gtksharp from mono on windows and it also does not start. The problem seems to be in the xwt backend, also in the original one from mono.

I used this .msi installer under https://github.com/mono/gtk-sharp/releases/tag/2.99.3

Test branch: https://github.com/MakiWolf/dotdevelop/tree/hackweek2nugetgtkxwtgtk3

I assume the problem here is that you installed the 32 bit version of the libraries but are executing a 64 bit application?

The original mono gtk3 installer have only a 32 bit version. And using the new nuget package and the libraries from msys2 also have not worked.

https://github.com/GtkSharp/GtkSharp/wiki/Installing-Gtk-on-Windows

But on GTK2 under this branch the 32bit installation of the libraries worked: https://github.com/MakiWolf/dotdevelop/tree/windowslinuxbuild

Another strange thing when I use this working gtk2 branch under https://github.com/MakiWolf/dotdevelop/tree/windowslinuxbuild
And make in this line a Console Output with WriteLine

https://github.com/easysimplified/xwt/blob/042a2c85edb02447f45a65aa1a46fd9cbbcf6dbf/Xwt.Gtk/Xwt.GtkBackend/GtkEngine.cs#L135

Console.WriteLine("loc:"+loc);

It outputs:

loc:C:\msys64\home\Marku\windowslinuxbuild\main\build\bin\Xwt.Gtk.Windows.dll

strange when I look with a file manager here there is no file Xwt.Gtk.Windows.dll only a file without windows in the name!?
