Desktop application development begins with selecting the right platform approach: native (Windows/macOS/Linux), cross-platform frameworks, and the distribution method. A clearly defined MVP and an early prototype help validate workflows, performance requirements, and the overall UX on real machines.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable daily use, while an update system and crash reporting ease ongoing maintenance.
