VistaDB 4.0 Support

We have made a new version of the EntitySpaces Developer available (2009.2.1005.0) that supports VistaDB 4.0. The official release of VistaDB 4.0 was just made available and within 24 hours of it’s release we have added support for it. The EntitySpaces Developer version is available but we haven’t updated the Trial version yet. That will happen within the next 24 hours or so. You can install this right over the top of the 2009.2.0928.0 release, just make sure you have Visual Studio closed. There are now two choices on the Settings tab when connecting to VistaDB.

1. VistaDB   = VistaDB 3.x
2. VistaDB4 = VsitaDB 4.x

Also, there is a new EntitySpaces DataProvider that is used with VistaDB 4.x. The assembly name is EntitySpaces.VistaDB4Provider.dll. In your config file in the EntitySpaces connection information you use “EntitySpaces.VistaDB4Provider” as the provider. There are no VistaDB 4.0 compact framework providers as VistaDB 4.0 does not currently ship a Compact Framework assembly.

Fixed the “||” Issue

There was an issue with the || (or) symbol. This has been fixed. In C# you should always be able to use && for AND and || for OR. Of course, in VB.NET you just use the OR and AND keywords.

VB.NET Nullable Type Query Issue

There was an issue that was causing VB.NET developers to use .Value when used nullable types in DynamicQuery statements. This has been fixed.

From Mobile Devices to large scale enterprise solutions in need of serious transaction support, EntitySpaces can meet your needs. Whether you’re writing an ASP.NET application with Medium Trust requirements, a Silverlight/WCF application, a Mono application, or a Windows.Forms application, the EntitySpaces architecture is there for you. EntitySpaces is provider independent, which means that you can run the same binary code against any of the supported databases. EntitySpaces is available in both C# and VB.NET. EntitySpaces uses no reflection, no XML files, and sports a tiny foot print of less than 200k. Pound for pound, EntitySpaces is one tough, dependable .NET architecture.
