visual studio 2013 --"Microsoft SQL Server Data Tools package did not load correctly"

最近装visual 2013，运行提示一点问题，按照百度的结果果然成功了。

The 'Microsoft SQL Server Data Tools' package did not load correctly.The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file 'C:\Users\...\AppData\Roaming\Microsoft\VisualStudio\12.0\ActivityLog.xml'.

ANSWER:

Go to Add/Remove Programs, search for "Microsoft SQL Server Data Tools" and repair. 

其实就是到控制面板里，修复下就OK.

又遇到同样问题的可以试试。。。
