Rajan - your demo shows UniObjects Toolkit for DotNet at version 1.2.0 and I'm eager to check this out, but searching the Rocket website the latest version available for download is UO v1.1.1 . Is there a way to get the newer bits?

  • Hi Rich, Thank you for asking this question. We are running BETA of U2NETDK v1.2.0. You can join the BETA program. Either you contact U2 Support or send me an email. We will include in our BETA. Then you can download U2NETDK v 1.2.0. You can use this email to contact U2 Support. U2 Askus Mailbox Rajan – Rajan Kumar Dec 21 '12 at 20:55

Please note that U2NETDK v1.2.0 has been released and is no longer in beta. To use the Visual Studio Add-Ins you must acquire a license from your software provider. The ADO.NET provider and native API (formerly UO.NET) are available at no cost. U2askus@rocketsoftware.com is a good email for general product information; if you have a support maintenance contract with Rocket Software, the email is u2support@rocketsoftware.com. If you obtain your maintenance from an ISV or distributor, you would contact them for support.
