Hi,@William Liu. Welcome Microsoft Q&A.
The difference in memory usage between a WPF application and a WinForms application is not necessarily due to any settings on your Windows laptop. It's a result of the different architectures and technologies used by WPF and WinForms.
WPF (Windows Presentation Foundation) is a more feature-rich and flexible UI framework compared to WinForms. It offers advanced graphics capabilities, hardware acceleration, vector-based rendering, and a more extensive set of controls. However, these additional features come at the cost of increased memory consumption.
On the other hand, WinForms (Windows Forms) is a simpler and lightweight UI framework that provides basic UI controls and simpler rendering. It is designed to have a smaller memory footprint compared to WPF.
The difference in memory usage you observed is expected and can be attributed to the underlying architectural and design choices of each framework. WPF applications tend to use more memory due to their advanced features and the overhead required for rendering and managing the UI elements.
It's worth noting that the memory usage of an empty template project may not accurately represent the actual memory requirements of a real-world application. As you start adding functionality, controls, and resources to your application, the memory usage will vary based on your specific implementation.
In summary, the higher memory usage of a WPF application compared to a WinForms application is generally a by-design behavior due to the differences in their respective architectures and feature sets.
