對(duì)sl傳統(tǒng)的開(kāi)發(fā)方式進(jìn)行了集成和封裝，核心模塊基于MVVM，通用的CRUD ViewModel，只需要定制自己的Xaml View，提供了非常便捷的快速開(kāi)發(fā)方式; 采用了Silverlight 5.0 + EF4.1 Code First + Ria Service SP2 + Ria Service Toolkit + Silverlight Control Toolkit + Light MVVM；已經(jīng)實(shí)現(xiàn)了輕量級(jí)的權(quán)限管理，上傳模塊，內(nèi)容管理，作為實(shí)例，涉及到了sl開(kāi)發(fā)的各種技術(shù)難點(diǎn)和技巧，既可以作為學(xué)習(xí)，也可以作為項(xiàng)目開(kāi)發(fā)的原型

點(diǎn)擊預(yù)覽 | 源代碼

支持動(dòng)態(tài)加載.xap，面向插件開(kāi)發(fā)

RapidSL.SL.App.Portal提供主框架的UI邏輯，只需要開(kāi)發(fā)自己的App，如RapidSL.SL.App.Main

然后配置菜單：

XapHost控件提供動(dòng)態(tài)下載.xap及加載

 
 
 
 

  
  
  
  
public XapHost(string xapUri, string viewName = null) 
  
  
  
  
         { 
  
  
  
  
             InitializeComponent(); 
  
  
  
  
             this.FileName = xapUri; 
  
  
  
  
             var xapLoad = new XapLoader(xapUri); 
  
  
  
  
             xapLoad.DownloadProgressChanged += (s, e) => 
  
  
  
  
             { 
  
  
  
  
                 this.TotalSize = (e.TotalBytesToReceive * 1d / 1024 / 1024).ToString("0.00"); 
  
  
  
  
                 this.Percentage = e.ProgressPercentage; 
  
  
  
  
             }; 
  
  
  
  
             xapLoad.LoadCompleted += (s, e) => 
  
  
  
  
             { 
  
  
  
  
                 this.Content = e.Element; 
  
  
  
  
             }; 
  
  
  
  
             xapLoad.LoadControl(null, viewName); 
  
  
  
  
         }
 
 
 
 

對(duì)Resource的支持

找到所有標(biāo)識(shí)有 StaticResourceAttribute的類，然后創(chuàng)建相關(guān)實(shí)例，并注入到Application.Resources，相當(dāng)于在 App.xaml里手寫資源

實(shí)現(xiàn)了資源管理器對(duì)資源進(jìn)行注入管理
