[possible issue] Add missing base class inheritance

✅ Add missing base class inheritance

The generated JSON serialization context class should inherit from JsonSerializerContext to enable proper JSON serialization functionality.

-internal sealed partial class {{protocolVersion}}JsonSerializationContext;
+internal sealed partial class {{protocolVersion}}JsonSerializationContext : JsonSerializerContext;

Apply this suggestion Suggestion importance[1-10]: 10

Why: The suggestion fixes a critical issue by adding the required base class inheritance, which is essential for the JSON serialization context to function properly. This matches the implementation in the individual version files.

[possible issue] Fix parameters initialization logic

✅ Fix parameters initialization logic

The constructor assigns parameters directly to Parameters property only when not null, but the property already initializes a new dictionary. This can lead to inconsistent state. Consider removing the default initialization.

-public Dictionary<string, object> Parameters { get; } = new Dictionary<string, object>();
+public Dictionary<string, object> Parameters { get; private set; } = new();

Apply this suggestion Suggestion importance[1-10]: 7

Why: The suggestion correctly identifies a potential state inconsistency issue where the Parameters property has both an initializer and conditional assignment in the constructor, which could lead to confusion and bugs.

PR 15144 (2025-01-24)

[possible issue] Fix constructor initialization pattern

✅ Fix constructor initialization pattern

The constructor is not properly initializing the page size. The property pageSize should be set directly instead of using PageDimensions to avoid potential null checks and exceptions.

dotnet/src/webdriver/PrintOptions.cs [66-69]

Apply this suggestion Suggestion importance[1-10]: 8

Why: The suggestion correctly identifies a potential issue where using PageDimensions setter could throw an exception during object construction. Direct field initialization is safer and more appropriate for constructors.

[general] Remove redundant null validation

✅ Remove redundant null validation

The SetPageSize method duplicates the null check that's already present in the PageDimensions property. Remove the redundant validation to maintain DRY principles.

     this.PageDimensions = pageSize;
 }

Apply this suggestion Suggestion importance[1-10]: 5

Why: The suggestion correctly points out code duplication in null validation, as PageDimensions property already handles null checks. While valid, the impact is mainly on code maintainability rather than functionality.

[general] Optimize map creation efficiency

✅ Optimize map creation efficiency

The toMap() method creates new Map instances unnecessarily. Optimize by using a single mutable map and conditionally adding the contexts.

[Enhancement] Separate package managers into individual entries for more precise control

✅ Separate package managers into individual entries for more precise control

Consider using more specific manager names for Python-related package managers. Instead of using a catch-all "pip_requirements, pip_setup, pep621", you could separate them into individual entries for more granular control.

[Enhancement] Use null-coalescing operator with null-conditional operator for safer string conversion

✅ Use null-coalescing operator with null-conditional operator for safer string conversion

Consider using the null-coalescing operator (??) instead of the null-conditional operator (?.) followed by ToString(). This will provide a default empty string if the value is null, avoiding potential null reference exceptions.
