.NET 2.0 and x64 Compatibility Problem?

[Guest]

Hi.

I used to have a working project under the following configuration:

1) Windows Server 2003, Standard
2) .NET Framework 1.1
3) Visual Studio 2003 Enterprise
4) DirectX SDK, Early 2005

I now have the following setup:

1) Windows Server 2003, Standard *x64*
2) .NET Framework *2.0*
3) Visual Studio *2005 Express*
4) DirectX SDK *October 2005*

When I try to launch my project, I get an error in the constructor of my
audio streaming class (I'm doing realtime audio generation). I won't go into
details on that though, becuase the error is very strange:

System.BadImageFormatException: is not a valid Win32 application.
(Exception from HRESULT: 0x800700C1).'
at Wavelet_Tracker.AudioSystem.ctor()
at Wavelet_Tracker.Application.ctor() in Application.cs:line 144
at Wavelet_Tracker.Application.Main() in Application.cs:line 107

I trust the error is not with my code, which was working OK. The error seems
to suggest some sort of deeper problem. I will however post my code if needs
be, I'm hoping though that someone will point me to some reading on
compatibility problems that I missed before embarking on this 4-way upgrade
:-S.

Thanks in advance,
Aaron.

As a followup, in case anyone thought I was really dumb, I *can* run new
projects created with Visual C# Express. I *can't* run my project, or any of
the DirectX sample projects.

First thing I would do is reinstall the DirectX SDK and then try again.

As you could see express has 64bit compiler support.
that might be the problem....

That is, if you use unsafe code (i.e. pointer or IntPtr).
However I would think it's for C++ code.
Look in your C# project property, maybe you could you could select target
platform somewhere?
Because: remember: IntPtr are not the same size on x64 computers...
