I'm not sure if this is an available avenue for you, but perhaps you can host the assembly using WCF or ASP.NET web services and use some sort of authentication scheme (LDAP, public/rpivate key pairs, etc.) to ensure only allowed clients connect. This would keep your assembly physically out of anyone else's hands and ... |
You have to watch out with BCP/BULK INSERT because neither BSP or Bulk Insert handle this well if the quoting is not consistent, even with format files (even XML format files don't offer the option) and dummy ["] characters at the beginning and end and using [","] as the separator. Technically CSV files do not need to... |
If it contains anything about things like form, button, etc.. it's not a business logic, it's presentation layer. If it contains persistence to file or database, it's DAL.

What exactly consists of 'Business Logic' in an application? |

I have heard umpteen times that we 'should not mix business logic with other code' or statements like that. I think every single code I write (processing steps I mean) consists of logic that is related to the business requirements..

It sounds like you want to track changes to specific entities over time, e.g. ID 3, "bob", "123 main street", then another ID 3, "bob" "234 elm st", and so on, in essence being able to puke out a revision history showing every address "bob" has been at.

Do C++ logging frameworks sacrifice reusability? |

In C++, there isn't a de-facto standard logging tool. In my experience, shops roll their own. This creates a bit of a problem, however, when trying to create reusable software components. If everything in your system depends on the logging component, this makes the software less reusable, basically forcing any downs... |
If you want to do the first one you might want to use XML for the Employees table too. Most newer databases allow you to query into XML fields so this is not always a problem.

Try verifying the certificate chain using the [X509Chain][1] class. This can tell you exactly why the certificate isn't considered valid.

C# has a better GUI with WPF, something that Java has traditionally been poor at.

It might be useful as a tool to lean on as you refactor to testability in a large code base. I can see how you might use such techniques to enable smaller changes and avoid a "big bang" refactoring.

Yes. But dependency injection will help in this case.
