While I mentioned it was working in #1, I just discovered HS won't start after rebooting the computer. It may have worked the first time because I directly launched the plugin EXE while HS was already running. Upon rebooting, HS failed to launch, and I got several "do you want to debug this" popup windows for a couple HS plugins.

I can't help but wonder if it's the ilmerge stuff you're doing. As far as I know, the current recommended way to handle DLL dependencies in HS plugins is to put them in their own directory. See the assembly binding section here

I've got my builds configured to automatically get the output in the correct structure. I use this ps script in the AfterBuild section of my csproj.

If you look at your HS installation directory, you'll probably see several other plugins doing the same thing.

I'm no expert, though, so take that with a grain of salt.

What devices does this speak to? Can it speak to multiple devices? What's the status of this plugin?

Thanks!
