在Visual Studio 2013中设计Windows Phone 8应用程序，我只是尝试将Telerik的RagGauge控件添加到我的页面上。
当我添加时，我收到了一个例外。如果我在Visual Studio中关闭设计器然后再次打开页面，我会在页面上看到带有RadGauge字样的控件。我点击这个，再次发生异常。
异常
FileNotFoundException: Could not load file or assembly 'Microsoft.VisualStudio.Shell.11.0, Version=11.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
