Building a desktop app begins by selecting an appropriate platform approach: native for Windows/macOS/Linux, cross‑platform frameworks, and how you’ll distribute it. A clearly defined MVP and an early prototype help confirm workflows, performance requirements, and the overall user experience 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) keeps the app dependable in everyday use, while an update system and crash reporting streamline ongoing maintenance.
