Yes, Blue Prism does support applications built in any .NET language. I don't think there is any guidance specifically for that. Are you encountering any issues with it?
Anyway, think of it like this. AA and UIA were both made by Microsoft and so was VB. If you're having trouble using either of those spy modes, it's not likely an issue with the technology the app is built on but a setting on the device, perhaps security or other.
