wcf

I've been using PrincipalPermission for a while in wcf services. [PrincipalPermission(SecurityAction.Demand, Role = SecurityRoles.CanManageUsers)]

although now i have a requirement to simplify roles by business unit. - currently aspnet_roles has fine grained can* permissions.

Here is my approach and wanted to see if anyone can provide feedback, code review before i implement my suggestion.

1) aspnet_roles - business unit role

2) create permission table and Role_Permission table and User_Permission table (many to many)

3) create custom CodeAccessSecurityAttribute + that looks at new tables [CustomPermissionCheck(Security.Demand, HasPermission="can*")] first iteration i'll statically new the dependent repository.. ideally i would like an aop style attribute that has repository injected IPermissionRepository.HasPermission(...);

If i approach new aop way i probably will stop inheriting from CodeAccessSecurityAttribute -- what do the security guys have to say about this?

has anyone else solved this, is there something in the framework that i've missed?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More

I've been messing with this for about a day and a half now sifting through .NET reflector and MSDN docs, and can't figure anything out...
