I am working thru chapter 3. On page 64, I add the IsDuplicate method. This contains a reference to Execute<DuplicateCheck...

When I compile I get this error message
DuplicateCheck' is inaccessible due to it's protection level

I downloaded chtr 3 code.

I added :
DuplicateCheck.cs to the DAL

The two overloads I found in the ENTBaseData.cs
protected static bool IsDuplicate(...

Has anyone else run into this?...and found a fix?

Hello
I have not encountered this problem because I have followed book's class definitions step by step.
check that your classes are defined as 'public' in your program. if you don't put 'public' keyword in the begining of class definition, then class will be defined as 'private'. if your problem does not solved replace 'internal' keyword with 'public' in the definition of DuplicateCheck class to test that is it accessible after this change.

Thanx for your reply..I'm all set .I entered the ISDuplicate method into the ENTUserAccountEO.cs in the BLL...I should have entered it in the ENTUserAccountData.cs in the DAL Framework
