Answer 2

+2 A:

Found an F# example here.

Made a Boo example based on it. The source code:

namespace Hello
import System
import System.Windows
import System.Windows.Controls

class MyPage(UserControl):
    def constructor():
     canvas = Canvas()
     textblock = TextBlock()
     textblock.FontSize = 24
     textblock.Text = "Hello!"
     canvas.Children.Add(textblock)

     self.Content = canvas

class MyApp(Application):

    def constructor():  
     Startup += onStartup


    def onStartup(sender, e):

     self.RootVisual = MyPage()

Built with:

booc -nostdlib -target:library -lib:"C:\Program Files\Microsoft SDKs\Silverlight\v2.0\Reference Assemblies","C:\Program Files\Microsoft SDKs\Silverlight\v2.0\Libraries\Client" -r:System.Windows.dll -r:System.Windows.Controls.dll Hello.boo

The AppManifest.xaml:

<Deployment xmlns="http://schemas.microsoft.com/client/2007/deployment" 
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
            EntryPointAssembly="Hello" 
            EntryPointType="Hello.MyApp" RuntimeVersion="2.0.31005.0">
  <Deployment.Parts>
    <AssemblyPart x:Name="Hello" Source="Hello.dll" />
    <AssemblyPart x:Name="Boo.Lang" Source="Boo.Lang.dll" />
  </Deployment.Parts>
</Deployment>

Then made an ordinary .zip file containing AppManifest.xaml, Hello.dll and Boo.Lang.dll (one of Boo libraries from it's directory) and renamed it into hello.xap.

An html to look at it:

<html>
<head></head>
<body>
<object id="SilverlightPlugin" data="data:application/x-silverlight,"
 type="application/x-silverlight-2" width="450" height="540">
  <param name="source" value="hello.xap"/>

  <a href="http://go.microsoft.com/fwlink/?LinkID=124807" style="text-decoration: none;">
    <img src="http://go.microsoft.com/fwlink/?LinkId=108181"
     alt="Get Microsoft Silverlight" style="border-style: none"/>
  </a>
</object>

</body>
</html>

The resulting hello.xap is 43 KB, which is much better than 1.5 MB that I got with IronPython and DLR.
