LINQ to Entities does not support the method...System.Object CompareObjectEqual
When I execute the code below I receive the error message:
LINQ to Entities does not recognize the method 'System.Object CompareObjectEqual(System.Object, System.Object, Boolean)' method, and this method cannot be translated into a store expression.
It seems to be occurring on the line For Each row2 in PCstudent.

First of all you're doing things the most difficult way possible (row by row update in code) instead of single update to the database; that said, nothing looks incorrect on the surface of things. You might check the definition of 'dbPC.Residencies' to make sure it's defined correctly, and you may need to put an "if (PCStudent.Any())" check before your "For Each", though it ought to work as written.
