Canon.EDSDK

Modern .NET 10 P/Invoke bindings for Canon's EDSDK (13.14.40).

Features

• LibraryImport throughout — all methods source-generated, NativeAOT compatible
• nint handles throughout (not IntPtr)
• EdsError return type on all methods instead of raw uint
• Typed enum params — EdsPropertyId, EdsCameraCommand, EdsObjectEvent etc.
• readonly struct with InlineArray fields (no MarshalAs byte arrays) and lazy string decode
• Typed EdsGetPropertyData / EdsSetPropertyData overloads using unsafe stackalloc
• [Flags] on EdsFileAttribute, EdsEvfOutputDevice, EdsBracket

Usage

using Canon.EDSDK;

// Initialize SDK
EDSDK.EdsInitializeSDK();

// Get camera list
EDSDK.EdsGetCameraList(out nint cameraList);
EDSDK.EdsGetChildAtIndex(cameraList, 0, out nint camera);

// Open session
EDSDK.EdsOpenSession(camera);

// Set property
EDSDK.EdsSetPropertyData(camera, EdsPropertyId.ISOSpeed, 0, 0x00000068); // ISO 800

// Take picture
EDSDK.EdsSendCommand(camera, EdsCameraCommand.TakePicture, 0);

Requirements

Canon's EDSDK binary (EDSDK.dll) is not included — it must be obtained from Canon's Developer Community. Place it in lib/win-x64/.
