Desktop application development begins by selecting the suitable platform strategy: native for Windows/macOS/Linux, cross-platform frameworks, and the distribution approach. A well-defined MVP and an early prototype help validate workflows, performance requirements, and the overall UX on real devices.

As the product matures, stability, updates, and packaging become priorities. Careful handling of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures the app remains reliable in daily use, while an update mechanism and crash reporting simplify long-term maintenance.
