asp.net text templates for base entities and good design patterns

Hi,

I was introduced lately to the great feature of Text Templates in ASP.NET projects. I use Entity Framework 4 on my projects and was wondering if there is a good Text Template out there which can auto generate base business objects classes from the given edmx file.
I saw the T4 toolbox project which provided some text templates into VS2010 but haven't found anything which produces a rally helpful code.

On my projects I often use design patterns like in the nopCommerce project, i.e. Unity IoC, business services (sometimes UnitOfWork) and etc.

Is there anything good out there which you can recommend?

Thanks
