AOT/Trimming Safe

AOT/Trimming Compatible

P11 UI components work flawlessly with AOT compilation and trimming enabled. Your project will compile and run without issues.

Reflection Operations: Generally compatible, with development-time warnings for patterns that may require explicit preservation (e.g., `Convert.ChangeType` on unreferenced types).
Regular Expressions: Optimized for AOT compilation with source generators
Dynamic Types: No runtime compatibility issues
Generic Classes and Methods: Work seamlessly with AOT compilation
JSON Serialization: Compatible with trimming optimizations
String Formatting and Parsing: Safe for trimmed deployments
Culture-Specific Operations: Properly handled in AOT scenarios
Linq Expressions: Fully AOT/trimming compatible
JavaScript Interop: Magic strings in JS method calls
Trimmer Instructions: Correctly implemented where necessary
