I am using Visual Studio Express to author a dll for use in 64-bit AutoCAD. For this reason it needs to be compiled 64-bit. With that said I can find no way of getting Visual Studio to do this...I keep reading things about installing the SDK (I did) and then targeting it's toolset, but I can't find any way of doing this with the Express Version in VB.

I do know that Autodesk just put out a wizard that will set the platform info to 64-bit and that is supposed to work on express, the only problem is that it is using WPF and my existing project, that I am trying to covert, is not. The result is that my forms don't open in the designer when I import them, I assume they won't work either.

Any help would be greatly appreciated.

Thank you,
Jason Self

What ended up working was to use the template provided by AutoDesk (The new one is configured for AnyCPU) from there I added the existing project to the new solution and then simply drug the items I wanted into the new project.

You can not simply target a CPU with VB2010 Express, fortunately the template provided made the required changes.

while installing Visual studio.! it comes with option to select x86 OR x64 Bit version.!
if there is no option then "Dont worry.!" u r Operating system wil put it automatically under "Program files 32" folder

That doesn't seem to be true for Express Editions of Visual Studio, and the compiled dll's don't seem to work. The only available target platform is Active (x86)
