Building a desktop application begins by selecting an appropriate platform approach: native on Windows/macOS/Linux, cross-platform options, and the distribution method. A clearly defined MVP and an early prototype help validate workflows, performance requirements, and the overall user experience on real devices.

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