3-tier

问题 I saw in many places whenc# programmers uses 3-tire architecture, they tend to use interfaces between each layer. for example, if the solution is like SampleUI Sample.Business.Interface Sample.Business Sample.DataAccess.Interface Sample.DataAccess Here UI calls the business layer through the interface and business calls the data access in the same fashion. If this approach is to reduce the dependency between the layers, it's already in place with class library without additional use of the

问题 I am writing a design document and people on my team are willing to do the move from ASP.NET WebForm to ASP.NET MVC. This is great, but I have a hard time to understand how MVC workswith in a 3-tier (Data Layer, Business Layer and Presentation Layer) architecture.

I just had to change the code
