With a lot of controversy surrounding the upcoming RC1 release of Windows Vista (see Should There Be Vista Beta 3?), Microsoft is already releasing software which requires Vista RC1 to run.
Microsoft has released the August DirectX Software Development Kit (SDK) which includes a public pre-release of Direct 3D 10. Once again, Microsoft has released an SDK before releasing the platform needed to use parts of it.
According the Microsoft, "Samples and applications built with the Direct3D 10 Technology Preview in the August 2006 DirectX SDK require Windows Vista RC1 to run. The Windows Vista RC1 will be available to MSDN subscribers." While this is great news for developers, many are wondering when they will actually see Windows Vista RC1. Many Beta Testers are still expecting another 'interim' release before RC1 is released to the public.
