Desktop application development begins by selecting an appropriate platform approach: native for Windows/macOS/Linux, cross‑platform tools, and the distribution method. A clearly outlined MVP and an initial prototype help confirm workflows, performance requirements, and the overall UX on real devices.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file systems, access rights, offline functionality, and integrations (device APIs, peripherals, enterprise authentication) ensures everyday reliability, while an update process and crash reporting ease ongoing maintenance.
