1. Sliverlight 1.0 Beta Runtime
2. Sliverlight SDK 1.0 beta
3. Microsoft Blend 2.0 Preview
4. Sliverlight SDK 1.1 alpha
安裝 Sliverlight 專案樣板
為了讓 VS 2005 能夠開發 Sliverlight，先下載 Sliverlight SDK(Silverlight1.0SDK.zip)，取出其中的 SilverlightBetaToolsForVS2005.zip，將內容解開後放置在 %My Document%\Visual Studio 2005\Templates\ProjectTemplates\Sliverlight 1.0 beta，此時 VS2005 中可以使用 Sliverlight 專案，如下圖：
安裝 XAML IntelliSense
從 Silverlight1.0SDK.zip 中取出 silverlight.xsd，並放置在 C:\Program Files\Microsoft Visual Studio 8\Xml\Schemas 目錄下。
專案樣板程式碼研究
使用 Sliverlight 1.0 Beta 專案樣板產生的專案共會產生下面五個檔案：
