Building a desktop application begins by selecting an appropriate platform approach: native on Windows/macOS/Linux, cross-platform frameworks, and the deployment model. A clearly outlined MVP and an initial prototype help validate workflows, performance requirements, and the overall UX on actual devices.

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