Building a desktop app begins with selecting an appropriate platform approach: native (Windows/macOS/Linux), cross-platform tools, and the deployment method. A clearly defined MVP and an early prototype help verify workflows, performance requirements, and the overall UX on real devices.

As the product evolves, reliability, updates, and packaging become essential. Thoughtful management of file systems, permissions, offline operation, and integrations (device APIs, peripherals, enterprise authentication) ensures the application remains dependable in daily use, while an update system and crash reporting ease long-term maintenance.
