Building a desktop application begins by selecting the right platform approach: native on Windows/macOS/Linux, cross‑platform frameworks, and the distribution method. A clearly defined MVP and an early prototype help validate workflows, performance needs, and the overall UX on real devices.

As the product evolves, stability, updates, and packaging take center stage. Careful handling of file systems, permissions, offline mode, and integrations (device APIs, peripherals, enterprise auth) makes the app dependable in daily use, while an update mechanism and crash monitoring simplify long-term support.
