What is this book about? What is Sedna? What is Service Pack 2?
When Microsoft released Visual FoxPro 9.0 at the end of 2004, they began
asking the Fox community what enhancements would warrant development of a
VFP 10. In particular, they were looking for so-called "back of the box" features,
things that would be selling points for a new version.
Although a few big ideas were floated (especially breaking the 2GB limit for
table files), it rapidly became apparent that VFP 9 was a mature product. With its
major renovation to the Report Designer and even more open architecture than
earlier versions, VFP 9 contained the tools needed to develop powerful desktop
applications, as well as front-end and middle-tier objects for enterprise applications
using a back-end server.
On the other hand, looking forward, it was clear that there was a need for more
interoperability with .NET and other technologies. So in June, 2005, Microsoft
posted a roadmap for Visual FoxPro. It announced a project code-named Sedna,
focused primarily on interoperability. Sedna was proposed to comprise add-ons to the
core product, things that wouldn't require changes to VFP.EXE. At the time, it was
unclear whether Sedna would become VFP 9.1, VFP 9.5, VFP 10, or something else
entirely, as well as whether it would be free or for sale.
Following Microsoft's current model, the Sedna components were made available
to the community as they were being developed, through a series of Community
Technology Previews (CTPs).
In December, 2005, Service Pack 1 for VFP 9 was released; it contained a number
of bug fixes, as well as updates to some of the Xbase tools that come with VFP.
In March, 2007, Microsoft announced that Sedna, together with another Service
Pack, would constitute the final release for VFP. The Sedna components would be
released as open source, and placed on CodePlex, the community development site
for Microsoft products.
Service Pack 2 was released in October, 2007; Sedna took a few more months
to complete and was released in January, 2008. Both are available as free downloads
from Microsoft's VFP website (http://msdn.microsoft.com/vfoxpro). The Sedna
download includes the source code for its components. Updated versions can be
downloaded from the VFPX project at CodePlex
(http://www.codeplex.com/VFPX).
