No Managed DirectX for 64bit?
I posted this issue back during Beta 1 and was told that Microsoft will look at making a 64 bit Managed DirectX after the OS and the development environment was released.
That is way too late for those of us looking to release a 64 bit application any time soon!
Is there any update from Microsoft on availability of even a Beta Managed DirectX for the x64?
Thanks

Here is the reply I received from DirectX Team @ Microsoft:
The DirectX Team is currently in the planning phase and do not have
specific time-lines. But our goal is to have 64-bit version the ships
at the same time as Whidbey or shortly there after.Thanks,
DirectX

I downloaded the recent August 2005 DirectX9 SDK ... Also the Visual C#
Express Beta 2 and a Windows XP Professional 64 Bits Trial ... I tryed to
compile a very simple example and got this exception when I try to executed
the successfully-compiled example:
System.BadImageFormatException was unhandled
Message=" is not a valid Win32 application. (Exception from HRESULT:
0x800700C1)"

Vector3 l_v2 = new Vector3(4, 5, 6);
float l_flDot = Vector3.Dot(l_v1, l_v2);
}
}
}
The problem I think is that the Managed DirectX has been compiled using .NET
1.1 for ONLY x86 architecture ( I saw it with ILASM ) ... Must be this
because with x86 version of Windows XP Pro my example works ok....
So no... August 2005 SDK ( released YESTERDAY ) dont support Win64... Hope they port it to x64 soon.....
I am trying to use other approach... Just need to compile my program in Win64 for x86 intead of x64 ... the problem is how to make my .NET exe x86 and not x64 using the vc# express IDE ( with the command line I could do /platform:x86, but i dont see this option in the IDE ) Pls tell me if you have other ideas... I can't get the MDX9 libraries to run ok in win64 and i am desperated.
Thanks, but unfortunately this does not help. The suggestion essentially turns my app back into a x86 executable, which means that the limitations on the address space are back down to 2GB. The whole reason for pursuing the 64 bit application was to gain access to a larger address space. Until the Managed DirectX is released that links to the 64 bit version of DirectX, it seems that I am out of luck.

I downloaded the latest DirectX SDK, Oct 2005.
Still NO Managed DirectX for 64 bit.
