I have been a Visual Foxpro developer for 15 years and in the process of
learning C#. In Visual Foxpro we have always had Application Development
frameworks that we could use that build class libraries to make developing
an application for a client very fast. The basic foundation of business
classes, security and many other classes have been developed with hooks
that allow the programmer to just add additional code specifically to the
class they are building. Visual Foxpro has had inheritance for many years
so it make application development frameworks possible.

Is there any frameworks available for C# or known to be soon? The idea of
building libraries of a framework for application development is a HUGE
undertaking.

Thank you for your help,
