The Dynamics GP Blogster, Mariano Gomez, has begun an awesome series of posts about how a Dexterity developer can get started using Visual Studio Tools for Microsoft Dynamics GP.
Many of the concepts that make up the fundamentals of Dexterity development, such as Forms, Windows, Fields, Table Buffers, Triggers, etc. translate directly into the Visual Studio Tools environment.
Mariano describes the similarities and differences between the environments and then provides working examples. Have a look at the introductory post on his blog which has links to the other articles in the series.
Fantastic job Mariano. This has been on my wish list for a while.
