Question
I'm sharing my challenging experience using Tizen for .NET tools with my v4.0 TV, highlighting several pain points:
- Build Issues: Requires clean rebuilds for changes to take effect, otherwise runs previous version
- Debugging Limitations: F5 debugging doesn't work properly, making serious development difficult
- High-DPI Display Problems: Tooling doesn't scale properly on modern high-resolution screens
- App Deployment: No app icon appears in SmartHub, limiting testing capabilities
- Certificate Problems: Certificate tools fail unless PC date is rolled back
- Error Messages: Unhelpful error messages like "Closed closed"
- JDK Dependency: Only supports Oracle JDK, not OpenJDK
- VS2019 Compatibility: Tooling broken in VS2019 despite claims of support
- Emulator Availability: No emulators found for download
- Store Deployment: Unclear if .NET apps can be deployed to store
- Lack of Samples: No TV video streaming app examples available
- Sideloading Restrictions: Disabled for security reasons
- Forum Support: Limited helpful activity from Samsung
- Tooling Updates: No changes in 7 months
These issues make Tizen.NET development for TVs currently not recommendable.
