安装VS2010 SP1后，打开工程出现错误：
未能正确加载
“Microsoft.Entity.Design.BootstrapPackage.BootstrapPackage,Microsoft.Data.Entity.De..."
http://s15/mw690/5ef7acf5gdec9ac43c1ee&690“Microsoft.Entity.Design..."的错误" TITLE="VS2010打SP1后出现未能正确加载 “Microsoft.Entity.Design..."的错误" />
根据上面弹出框给出的错误提示找该路径下的文件，找不到ActivityLog.xml。注意将C:\User\Administrator\改为自己的用户名，在网上找到一个解决办法，把下面的代码拷贝到ActivityLog.xml文件中就可以了。
