Fix Invalid Trim Warning Suppression in BindConverter.cs

Description

Fixed invalid UnconditionalSuppressMessage attributes on BindConverter.cs that were causing incorrect trimmer behavior. The original blanket suppressions on 130-line methods claimed "methods don't have DynamicallyAccessedMembers annotations" which was factually incorrect. Extracted reflection operations into small helper methods with targeted suppressions and accurate justifications.

Problem Description

The original code had blanket suppressions on large Get<T>() methods (130+ lines) that claimed:

"methods don't have DynamicallyAccessedMembers annotations"

This was false. Methods like MakeArrayTypeConverter<T> DO have [DynamicallyAccessedMembers(All)] annotations. The incorrect suppressions caused the trimmer to make wrong decisions about what to keep/remove, potentially breaking:

• Array binding (e.g., string[], int[])
• Enum binding
• Nullable enum binding

Solution

Extracted reflection operations into small targeted helper methods with precise suppressions:

Helper Method	Suppressions	Justification
CreateArrayFormatter<T>	IL2060, IL2076, IL3050	"MakeArrayFormatter has DynamicallyAccessedMembers(All) constraint"
CreateEnumParser<T>	IL2060, IL3050	"ConvertToEnum has DynamicallyAccessedMembers(All) constraint"
CreateNullableEnumParser<T>	IL2060, IL2071, IL3050	"innerType is verified to be an enum at runtime"
CreateArrayParser<T>	IL2060, IL2076, IL3050	"Element type is validated at runtime"

Files Changed

File	Change Type
src/Components/Components/src/BindConverter.cs	Modified - Removed invalid blanket suppressions, added targeted suppressions
src/Components/Components/src/PersistentComponentState.cs	Modified - Added IL3050 suppressions for JSON serialization
