在vs2010中打开一个项目，需要引用一个dll，我把奋力从网上也下载了，在项目中也能引此dll，重新生成
项目失败，提示信息
错误 56 “ValidateXaml”任务意外失败。
System.IO.FileLoadException: 未能加载文件或程序集“file:///C:\Users\hongfu\Desktop\SilverlightFileUploadSrc\FileUpload\FJ.Core.dll”或它的某一个依赖项。不支持操作。 (异常来自 HRESULT:0x80131515)
文件名:“file:///C:\Users\hongfu\Desktop\SilverlightFileUploadSrc\FileUpload\FJ.Core.dll” ---> System.NotSupportedException: 尝试从一个网络位置加载程序集，在早期版本的 .NET Framework 中，这会导致对该程序集进行沙盒处理。此发行版的 .NET Framework 默认情况下不启用 CAS 策略，因此，此加载可能会很危险。如果此加载不是要对程序集进行沙盒处理，请启用 loadFromRemoteSources
