I just got my Samsung Galaxy Watch 2 and I'm eager to start developing for it. I set up my development environment for .NET apps and I'm now unable to use Tizen 4.0 as the target. I got a sample app running using Tizen 5.0, but it will not install on my watch as the version is too high. And the templates for Tizen 4.0 are nowhere to be seen. How can I get started using Tizen 4.0?
