Hi @lable there are few chances that you will see this extension appearing for ARM64 mainly because we have no way to test it and so far, you are the first one to request.
If you want to give it a try, you can clone the repository https://github.com/nanoframework/nf-Visual-Studio-extension and check if all is working, adjust what needs to be adjusted and submit a PR! Follow the instructions on how to debug an extension, you should be able to do it as well in ARM64.

Hi @Ellerbach PR is commit，but debuger is not work.

You have to clone the repository, install the Visual Studio extension tools for Visual Studio, open the solution and hit F5 to see if that's working or not.

Try to run it your way and still report the same error. Can I set breakpoints at that point in the code?

I guess yes. @josesimoes to confirm!

Don't know to which breakpoints you're refering to. If that's on the extension code, then yes, you can set them wherever you want.

Nothing new on this issue.
As reported above, there are no plans for an ARM extension.
