Desktop application development begins by selecting an appropriate platform strategy: native (Windows/macOS/Linux), cross-platform frameworks, and the distribution approach. A clear MVP and an early prototype help validate workflows, performance needs, and the overall UX on real devices.

As the product matures, stability, updates, and packaging become key. Thoughtful management of file systems, permissions, offline mode, and integrations (device APIs, peripherals, enterprise authentication) keeps the app reliable in daily use, while an update system and crash reporting streamline long-term support.
