When will the next PDC be?

PDC07 has been postponed indefinitely. Dennis already warned me just before MIX07 that Microsoft wouldn’t have anything to announce at the PDC after the MIX conference.


No new date for a PDC has been given, yet Microsoft already announced the date for MIX08! It will be held March 5-7, 2008 in Las Vegas.


So when will the next PDC be? The official statement by Microsoft is that it will be when they are ready to announce the “next wave of platform technologies”.  The .NET technology is still forbidden from entering large parts of the Windows Operating System.


Will Microsoft attempt to pull off a synchronized wave of platform technologies  again? Synchronizing the release of



  • Visual Studio .NET 2005, .NET 2.0 and SQL Server 2005

  • .NET 3.0 and Windows Vista

proved to be mighty difficult for Microsoft to pull off. They only managed to release Windows Vista by cutting the dependencies between the OS and .NET. .NET 3.0 is only bundled with Windows Vista. Vista doesn’t make use of it.


Vista even makes it very difficult to pull some things of using .NET. See my metadata API difficulty requiring me to use C++ and the fact that is is very difficult to create a decent Sidebar gadget using WPF.


The synchronization of .NET 3.5 and the ADO.NET Entity Framework failed. ADO.NET vNext has been delayed and will be released after the LINQ wave.


However, there is hope glimmering on the horizon. The new CoreCLR used by Silverlight 1.1 is able to co-exist with other CLR versions in one process. Silverlight will be a great technology for the Vista Sidebar. ASP.NET Ajax was released out-of-band. Microsoft has said that the next revision of the full CLR (remember .NET 3.5 still uses CLR 2.0) will also have this feature.
