Silverlight应用程序的最小例子是什么?
例如,我使用IronPython制作了以下示例:
from System.Windows import Application
from System.Windows.Controls import Canvas, TextBlock
canvas = Canvas()
textblock = TextBlock()
textblock.FontSize = 24
textblock.Text = 'Hello!'
canvas.Children.Add(textblock)
Application.Current.RootVisual = canvas
然后我使用 chiron 并创建了一个.xap文件。没有(显式)XAML,没有任何东西。是否有可能在C#中做同样的事情?我可以从命令行编译一个源文件?如果是这样,源代码是什么?
我的动机是尝试使用非常规语言创建silverlight应用程序,现在我被困在Boo ......

using System;
using System.Windows;
using System.Windows.Controls;
namespace MimimalSilverlightApp
{
public class App : Application
{
public App()
{
this.Startup += this.Application_Startup;
}
private void Application_Startup(object sender, StartupEventArgs e)
{
var canvas = new Canvas();
var textblock = new TextBlock();
textblock.FontSize = 24;
textblock.Text = "Hello!";
canvas.Children.Add(textblock);
this.RootVisual = canvas;
}
}
}

找到一个F#示例here。
基于它制作了一个Boo示例。源代码:
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()
内置:
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
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>
然后创建了一个普通的.zip文件,其中包含AppManifest.xaml,Hello.dll和Boo.Lang.dll(其目录中的一个Boo库)并将其重命名为hello.xap。
要查看它的HTML:
<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>
生成的hello.xap是43 KB,比使用IronPython和DLR获得的1.5 MB要好得多。
