The Patterns and Practices group at Microsoft is working on a VB6 to VB.NET Migration Guide. This guide is “ the bible” of VB migrations and it contains a lot of best practices around how to move applications. I definetely recommend you visit this site to get early access to the guide. ArtinSoft is writing most of the content in the guide so, as always, feedback is highly appreciated!!!
