This is a very basic/newbie question.

We are starting a .NET application using Strataframe framework. In the past (with VFP) I've had good results following the advice to subclass a purchased framework twice: once to be to shared among several apps and once again specific to an app.

It's been suggested that I create a dll for each level of inheritance classes. Where can I find step by step instructions to create dlls that hold each of the two levels of subclasses? Don't be embarrased that your suggestion is too basic :) I am asking how to do the equivalent of these VFP steps:

MD c:\IFramework\Classes
CREATE CLASSLIB C:\IFramework\Classes\IBusiness.vcx
CREATE CLASS IBusiness OF C:\IFramework\Classes\IBusiness.vcx AS Business FROM c:\Framework\Classes\Business.vcx

And then later,
MD c:\MyApp\Classes
CREATE CLASSLIB C:\MyApp\Classes\ABusiness.vcx
CREATE CLASS ABusiness OF C:\MyApp\Classes\ABusiness.vcx AS IBusiness FROM c:\IFramework\Classes\IBusiness.vcx

Thank you.
