Is it possible to control a Canon Camera on the latest .NET, currently .NET 6, or Core or Standard using their EDSDK.dll version 13.15.10.3 or any other lib via C#?

Control = snap a pic, save the image, set some settings, etc.

Canon provides a SDK EDSDK.dll and example C# code circa .NET 4.5 (2012). Current dll version is 13.15.10.3.

In framework the example app works and uses [DllImport("EDSDK.dll")]

The same code and lib on .NET 6 throws this error:

System.BadImageFormatException HResult=0x8007000B Message=An attempt was made to load a program with an incorrect format. (0x8007000B) Source=HardwareControl
StackTrace:
at EDSDKLib.EDSDK.EdsInitializeSDK()

Any info to how this would be done with the latest tools OR a strong 'noop, move on' is appreciated.Thanks!

/rant: MS basically pulled a 'New Coke' over .NET versions so here is a random primer.

    Have you tried explicitly using x86 or explicitly using x64 for the runtime? I suspect that's the problem (and my guess is that you want x86). Commented Jul 21, 2022 at 17:46
  • @JonSkeet it worked on x86! You have too much knowledge for one mind :) Thank you! Commented Jul 21, 2022 at 20:12
  • @TheDev6 hi, can you send me a link please to a working project of yours for the camera control ? i have eos 550d and i can't make it work and i'm trying for hours with the dll's and getting exception. please help me. Commented Jul 22, 2022 at 21:08
  • @EliotShein Unfortunately Canon makes you sign up for the sdk and samples. But EDSDKLib.EDSDK.EdsInitializeSDK(); is the line that will blow up if your dll is not found, or x86/x64 is not set on the class lib to the corresponding target of the dlls. Commented Jul 25, 2022 at 18:24
