VS2010 Database Framework comparison appears after text lines should not being null error

In the previous period due to other problems of VS2010 (see this http://www.cnblogs.com/churun/p/4821548.html), I re-installed VS2010 software, because my VS2010 was hit SP1 patch, So the SP1 patch has been re-installed, other issues resolved, and the database framework comparison appears after the text lines should not is a null error, resulting in a VS2010 crash.

Looked up a bit of information, found here the relevant information http://www.cnblogs.com/zyzlywq/archive/2012/02/21/2361121.html, need to reload VS2010 three files, Because my VS2010 hit SP1 patch, three files found in VS2010 due to the version of the problem is not installed, I went directly to SP1 patch inside find three files, reinstall found or not.

Later I run the SP1 patch inside the three files, remove them all, in the Open VS2010 installation package inside the three files to install, the problem is resolved.
