Hi,
I have got a new project with the following layers

1.Business Entity(Properties)
2.Business Layer
3.Data Layer(Connection String, Insert,Delete etc)
4.Application Layer(The form/design)

Can anyone tell me the order of adding projects. Because i am getting an error like "Can't add this layer because of Circular dependency"

Which is the order of reference?

Kindly help

Solution 2

1. First Add Business Entity reference to Business Layer
2. Second Add Data Layer reference to Business Layer
3. Third Add Business Layer reference to Application Layer

it is the proper sequence of Adding references.

If any issue then let me know.
