Where should I place additional classes in my MVC application?

I have an ASP.NET MVC application that uses the Linq to SQL classes placed in the Model folder.

I want to create some additional classes that I would normally place in my BLL, but I'm not sure how to work with MVC.

In WebForms, I will have DAL as class library. My BLL is like a class library that referenced my BLL. My website is referenced by both DAL and BLL.

The problem I am facing is that if I create a class library, this will have to reference my MVC app because it will need to use the types contained in my model.

If I then add (or try to add) a link to my class library, I end up with a circular dependency.

In web forms. My other option would be to place the classes in App_Code. Is there an equivalent to App_Code in an MVC app?

You can move all your models to a class library, can't you? Neither MVC nor VS is crazy. This will remove the model library dependency in the web application.

You can put this in the model folder. Since all business related classes are placed in this folder



For best practice see scottgu nerddinner . He created breathing classes in the nerdinner app.

I agree with the Model folder . You can arrange it for your heart (BLL, DAL, etc.).

I personally would avoid doing a separate build unless you have a good reason. I am a developer who tends to complicate problems too much, if I am not careful I try to follow the KISS (Keep It Simple Stupid) methods as much as possible, which usually does not allow me to get rid of a certain problem.

Try taking a look at the S # arp architecture. You can use the template they provide or use it as a reference to help you make decisions.
