Answer 1

A previous SO answer might be of help: Looking for simple rules-engine library in .NET

Have you looked at Windows Workflow Foundation

Answer 2

You can use BOO DSL features or use Rhino.DSL (we are using it as a macro engine for our project)

Answer 3

You can use a simple attribute based Rule Engine created by me:

Answer 4

You could use a commercial rule engine for .Net like InRule or the .Net version of IBM ILOG Rules or FICO Blaze Advisor. All of them make it easy to expose the rules to the business user in a way that makes it safe for them to edit them while providing technical hooks/APIs to make it easy to integrate the rules engine and execution.
