upgrade program for converting vb6 app to C#
Question
What is the best pathway to achieve this?
I know that VS2005 contains an upgrade mechanism. Do any later versions of VS contain this?

Microsoft has devoted a site to VB6->.NET migration .
They recommend a Free tool from ArtInSoft.
However I'm not sure I'd like to maintain a .NET application written in VB6-style. But on the other hand a tool could give you a good start and you can refactor the result where the tool does not produce code of your liking.

In the latest release of Visual Studio, the VB6 Migration wizard is now missing from the IDE.
A good external tool to perform a migration is VBUC .

One way to do this, which was used successfully in one of my previous teams, is:-
- use the free Microsoft tools for upgrading from VB6 to VB.NET (eg http://msdn.microsoft.com/sv-se/vbrun/ms788233 )
- compile the resulting code into assemblies
- decompile the assemblies into C# using a tool such as .NET Reflector, ILSpy, etc.
- cover the code in unit tests
- refactor until the code is managable (the initial code is likely to be quite ugly)
