Connecting to Pre-Release Versions of SQL Server 2008
Testing has identified some issues connecting to versions of SQL Server 2008 from applications using the .NET Framework v2.0 SP1 or developers using Visual Studio 2005 or Visual Studio 2008. These connectivity issues should be considered before upgrading any end-user systems to Vista SP1 Beta or Windows Server 2008 RC0, upgrading a backend database to SQL Server 2008, or upgrading developer systems to use Visual Studio 2008 Beta 2 or RTM.
Design-Time Connectivity Between Visual Studio and SQL Server 2008
Developers using Visual Studio 2005 or any version of Visual Studio 2008 will be unable to connect to any instance of SQL Server 2008. This is most significant for Visual Basic and C# developers as it will effectively block the use of any RAD features to aid in the development of their project.
This connectivity issue is principally caused by an incompatibility between the SMO layer that ships in Visual Studio and the SMO support provided in SQL Server 2008. Future updates will replace the appropriate Visual Studio components and allow connectivity and RAD feature support to the SQL Server 2008 November CTP and later.
Runtime Connectivity to SQL Server 2008 Using System.Data.SqlClient
On systems that have installed the .NET Framework v2.0 SP1, applications that use System.Data.SqlClient to provide data access will be unable to connect to certain versions of SQL Server 2008 depending on the .NET Framework version installed on the client and the SQL Server 2008 version installed on the server. If either end of the connection is updated without consideration of the system as a whole, applications that were previously working would no longer be able to connect.
SQL Server 2005 JDBC Driver v1.2 Official Release
The Microsoft SQL Server JDBC team is proud to announce the general availability of the v1.2 RTW release. This release continues Microsoft’s commitment to the JAVA community and non-Microsoft centric programming platforms. The driver can be found at http://msdn.microsoft.com/data/jdbc.
In this release we re-architected the communication stack resulting in significant performance and scalability improvements, as well as minimizing the driver memory footprint usage, especially with multiple active connections and resultsets. These enhancements are most visible when the ”responseBuffering=adaptive” connection property is used. The driver now supports SQL Server SSL encryption as part of our continual commitment to security.
