VS2010 DB Compare fails.. Reverse Engineer my @$$

This gave me much grief. In the end we ran a trace to find the last sql command and found this nugget of joy.

If you get hung up on:

"The Reverse Engineer operation cannot continue because you have been denied View Definition permission on at least one object in the '...' database." 

Run the following, and grant accordingly.

User is in a role that has view definition on sys and dbo, but thats not enough, apparently

GOOD
HasBaselinePermissions IsDeniedObjectPermissions
1      0

BAD
HasBaselinePermissions IsDeniedObjectPermissions
0      0

To fix:
USE master
GRANT VIEW ANY DEFINITION TO [randomSQLUser]
--REVOKE VIEW ANY DEFINITION TO [randomSQLUser]
*/
USE master
EXECUTE AS LOGIN = 'randomSQLUser' ;
