Hi,
We have built ARM64 versions of the critical platform-specific VisualGDB components (e.g. VisualGDBNativeARM64.dll, libssh2-arm64.dll), so they will work at full speed.
As for the external tools, we will have to wait until the ARM64 support in MinGW becomes mainstream and stable enough, and we see enough users interested in ARM64 builds. Until then, the normal x86 builds will work just fine through the emulator. If you don’t want to wait, you are always welcome to build the tools on your side and replace the VisualGDB-provided binaries – these are open-source tools built with open-source MinGW, so you don’t need any special parts from us to do it.
