I ran across a great .net project called Eto. It is basically “a cross platform desktop and mobile user interface framework” that is similar to xwt but more mature and supporting more platforms.
I have been testing the winforms and wpf back ends and they seem to work great. It also has a mac and iOS back end that appear to be fully functional. An android back end is planned for the future and I am currently investigating this.
It would be great if I can write the majority of my .net user interface code using one library and have it run on desktops and mobile. The only thing that would be lacking is windows rt support.
To start developing with Eto download the binaries from https://github.com/picoe/Eto/downloads. Add the reference to your project and start programming. See https://github.com/picoe/Eto/wiki/Preparing-your-solution for more details to setup your project.
VB.NET First App Example
Public Sub New()
Me.Title = "My Cross-Platform App"
Me.Size = New Size(200, 200)
Dim label = New Label()
label.Text = "Hello World!"
Public Shared Sub Main()
Dim app = New Application()
AddHandler app.Initialized, Sub()
app.MainForm = New MyForm()
C# First Example App
class MyForm : Form
this.Title = "My Cross-Platform App";
this.Size = new Size(200, 200);
dynamic label = new Label();
label.Text = "Hello World!";
public static void Main()
dynamic app = new Application();
app.Initialized += delegate
app.MainForm = new MyForm();
