Hey zhhaoo - a first-party SDK is a long-term maintenance commitment, not just a language binding. Luxonis has focused on the two main development paths, Python and C++, while Scratch serves more as an educational/onboarding option. So far, C# demand hasn’t been high enough to justify an official package and its ongoing support burden.
Is your use case specifically tied to C#, or why arent Python/C++ sufficient?
Best,
Oskar
