VistaDB 2.1 database for .NET has been released!
VistaDB is a small-footprint, embedded SQL database alternative to Jet/Access, MSDE and SQL Server Express 2005 that enables developers to build .NET 1.1 and .NET 2.0 applications.
VistaDB features SQL-92 support, small 500KB embedded footprint, free 2-User VistaDB Server for remote TCP/IP data access, royalty free distribution for both embedded and server, Copy 'n Go! deployment, managed ADO.NET Provider, data management and data migration tools.
This 2.1 update includes over 60 improvements, including new support for .NET 2.0 and Visual Studio 2005.
I've used VistaDB in some of my applications, and I must say it works as advertised. The 500kb footprint is a boon for desktop application deployment.
Here's the free download trial link. Try it out yourself!
