FAQPage Schema
How do I configure PerMonitorV2 high-DPI scaling in .NET WinForms?▼

To configure PerMonitorV2 high-DPI scaling in .NET WinForms, you update your SDK-style project application manifest to declare PerMonitorV2 compatibility, ensuring the UI renders crisply across different screen resolutions.

Can I use dependency injection with the Host builder pattern in .NET 8 WinForms?▼

Yes, you can use dependency injection in .NET 8 WinForms by configuring the Host builder pattern during application startup to inject services directly into your forms and UI components.

Does .NET 9 support dark mode for Windows Forms applications?▼

.NET 9 introduces experimental dark mode support for Windows Forms applications, allowing you to test and prepare your desktop tool's UI styling for future stable releases.

What is the best way to modernize a .NET Framework WinForms project?▼

The best way to modernize a .NET Framework WinForms project is migrating to an SDK-style project on .NET 8+, adopting new C# features, and implementing responsive UI development using async patterns.

Why do owner-drawn controls break with high-DPI scaling and how do I adapt them?▼

Owner-drawn controls break with high-DPI scaling because they bypass automatic layout adjustments; you adapt them by manually handling DPI changes and scaling graphics coordinates in your custom rendering code.
