Windows Forms or web app: how to choose
This is not a fan war. It is an operations question: who uses the system, with which peripherals, and what happens if the internet drops?
Choose Windows Forms if…
There are tills, scanners, thermal printers, or the shop cannot afford to “wait for Chrome”. Daily inventory happens at the counter.
Choose web (ASP.NET Core) if…
There are branches, traveling managers, or customers who must log in from home. The browser wins at distribution: you install nothing on each PC.
At Krats.tech we often combine: Windows in the shop, web panel for the office, Android for the field. One .NET.
Short questions
Is Windows Forms dead?
For counter SMEs, no. It stays predictable, fast to build in C#, and easy to run without training everyone on a SPA.
Can I start with one and add the other?
Yes. An MVP can be just the till or just the panel. The data model is designed so we do not paint into a corner.
