Desktop application development begins by selecting an appropriate platform approach: native for Windows/macOS/Linux, cross-platform frameworks, and the distribution strategy. A clearly defined MVP and an early prototype help validate workflows, performance requirements, and the overall user experience on real devices.
As the product evolves, stability, updates, and packaging become priorities. Careful management of file systems, permissions, offline behavior, and integrations (device APIs, peripherals, enterprise authentication) makes the application dependable in daily use, while an update system and crash reporting ease long-term maintenance.
