Can I inherit a class from one library to another library?

Ankit Rawat

in my project architecture, I have created a project and included 3 other class library projects and a class is inheriting from other library class.

[ex. model class is inherited in DAL (DataAccess layer), and DAL is further inherited in BAL (BusinessAcess layer)]

then my question is what are the advantages and disadvantages of this architecture?

should I create an instance of the class and then call its method when required?

I may not understood correctly and so I can just tell what's wrong in your approach.

1. [ex. model class is inherited in DAL (DataAccess layer), - Models should keep independent projects. Also it depends on whether it's Domain Model or View Model
2. DAL is further inherited in BAL (BusinessAcess layer)] - Usually DAL interfaces should be injected inside BL in a loosely coupled manner

No, you should create object of DAL using interface in BAL to use functionalities

actually my question title is incorrect. I want to know that is this approach is good, that: inherit the DAL layer into BAL.
