我装了VS2010 旗舰版(版本10.0.30319.1 RTMRel)
.NET Framework 版本 4.0.30319 RTMRel
SilverLight 运行时版本 4.0.50524.0
为什么我再安装SDK：Silverlight4_Tools，会提示以下错误呢?
Installation Requirements:
VisualStudio 2010 or Visual Web Developer Express 2010 or Visual Phone DeveloperExpress 2010 that matches the language version of Silverlight Tools 4 must beinstalled before installation of Silverlight Tools can continue.
