I’m developing an enterprise scale application using ASP.Net and MM .Net . I’m not using some of the features that come with MM for web development, like registering business object with the web form so user interface controls are updated based on the data retrieved by a business object. I am using MM to create business objects, perform Security, Localization, etc..

MM does an excellent job of creating a framework from which to base your business objects. The business rules are also well designed. The framework gives you quite of bit of flexibility, but it took a while to get used to overriding methods and creating sub-classes of MM.

Localization has worked well.

Security also works well for providing different access rights based on Roles or Users. I’m currently trying to find a way of implementing LDAP.

With that said, It has taken me quite of bit of time to get comfortable with using the framework. I had not used a framework before using MM and was unfamiliar with them in general. The framework is not perfect, but you can ‘usually’ tailor the framework to fit your needs by overriding methods or creating sub-classes.

I strongly suggest you go to Oak Leaf’s home page (http://www.oakleafsd.com/) and download the Developer's Guide and read through it to better understand how the framework works.

Bottom line, I ended up buying the framework for my personal business( I was using the company’s license to develop their software).

Hope this helps,
