Build #6
VistaDB 4.0 shipped October 2, 2009 as Build 6 with only minor changes from the previous release candidate.
See the detailed Getting to know VistaDB 4 post for more information on what has changed and is new in VistaDB 4.
New TODO Sample
Added TODO Sample N-TIER Application. The sample includes a simple TODO list application, with the presentations being totally abstracted from the actual data storage. The purpose of this sample is to demonstrate a well structured 3 tier application that uses a range of presentation technologies to the same underlying foundation using VistaDB as an embedded database.
Inside the sample you will find a WCF service, Business Logic Layer (BLL), Data Access Layer (DAL), and 3 different presentation layers (ASP.NET, WPF, and Silverlight 3). This sample is a much larger and more complex sample than we have presented previously. It demonstrates writing a well structured 3 tier application with VistaDB as the common data storage across multiple types of .Net applications.
ASP.NET, WPF, and Silverlight 3 are used as presentation layers (WPF and Silverlight require additional downloads as noted in the TODO Help file). Each of the presentation layers is represented in a separate solution with the other projects linked in from the common directory path.
Medium Trust
Fixed an issue with Web Applications, medium trust, and VistaDB running from the GAC.
Pack Database overload
Fixed an issue with pack called on a VistaDBConnection that was wrapped around a database opened via DDA. This is now an error since the VistaDBConnection does not know enough about the underlying database to pack. Pack should be called from DDA when the open was performed from DDA.
Trial Version will follow soon
The VistaDB 4 trial version is almost ready to ship, we are internally testing it right now. We also have to update the trial signup pages and followup emails to discuss the 4 version of the product.
