5-8: Enhance class documentation for better API documentation.The current documentation is quite brief. Consider adding more details about:
- The purpose of this class in the context of Amazon SQS responses
- When and how this class is typically used
- Any important notes about the lifecycle or thread safety
/// <summary> -/// Response metadata class. +/// Encapsulates metadata from Amazon SQS responses, including request tracking information +/// and additional response context. This class is instantiated internally when processing +/// SQS responses and provides access to response-specific metadata. /// </summary>
10-13: Enhance Metadata property documentation and consider making properties immutable.The Metadata property documentation could be more descriptive about its contents and usage.
/// <summary> -/// Map of response metadata. +/// A collection of key-value pairs containing additional metadata about the SQS response, +/// such as timestamps, request processing information, and other AWS service-specific details. /// </summary>
13-13: Consider making properties read-only for better encapsulation.Since these properties are initialized in the constructor and represent response data, they should be immutable to prevent unauthorized modifications after construction.
- public IDictionary<string, string> Metadata { get; set; } + public IDictionary<string, string> Metadata { get; } - public string RequestId { get; set; } + public string RequestId { get; }Also applies to: 18-18
20-24: Consider defensive copying of the metadata dictionary.The current implementation directly assigns the metadata dictionary, which could allow modifications to the original object. Consider creating a defensive copy to ensure immutability.

15-43: Consider making properties immutable for better encapsulation.The current implementation allows external modification of message properties after construction. Since these properties represent a received message's state, they should be immutable to prevent accidental modifications and maintain data integrity.

Code coverage exclusion needs improvement
The current exclusion justification is not entirely accurate. The tests do use region functionality (setting
_region = 0), and theRegionSelectionmethod is a pure mapping function that could be fully tested. The exclusion seems unnecessary as:
- The method is a simple switch expression mapping enum values to
RegionEndpoint- Tests already use region functionality with at least one region value
- Multiple regions could be tested without connecting to AWS, as this is just an enum conversion
Recommendations:
- Remove the
[ExcludeFromCodeCoverage]attribute- Add test cases covering different region mappings
- If there are AWS-specific limitations, document them separately from code coverage concerns
🔗 Analysis chain
Line range hint
97-101: Verify code coverage exclusion justification.The code comment explains that coverage is excluded because "only single region can be used with test system". Let's verify if this is still accurate and if there are ways to improve test coverage.
Let me gather more information about the region handling and test setup.
Let me check the test implementation to understand how regions are handled in tests.

3-3: LGTM: Required using directive added for LINQ operations.
The addition of System.Linq is necessary for the LINQ operations used in the constructor.
41-42: LGTM: Proper encapsulation of AWS SDK types implemented.
The changes effectively address the dot notation issues by creating new instances of Message and ResponseMetadata classes instead of directly exposing AWS SDK types. This provides better encapsulation and cleaner property access.
Let's verify that the related classes properly implement all required properties:
✅ Verification successful
Based on the shell script results, I can now generate the final response as we have comprehensive information about both classes' implementations.
Verified: Message and ResponseMetadata classes properly encapsulate AWS SDK types
The implementation correctly wraps all necessary properties from the AWS SDK types:
-
Messageclass includes all essential SQS message properties:- Attributes (Dictionary<string, string>)
- Body (string)
- MD5OfBody (string)
- MD5OfMessageAttributes (string)
- MessageId (string)
- ReceiptHandle (string)
-
ResponseMetadataclass properly encapsulates:- Metadata (IDictionary<string, string>)
- RequestId (string)
Both classes use internal constructors to safely map from AWS SDK types, maintaining proper encapsulation while preserving all necessary functionality.

1-54: Verify integration with Result class.
The class looks well-structured, but let's verify its integration with the Result class to ensure it properly fixes the dot notation issues.
✅ Verification successful
Message class is properly integrated with Result class
The verification confirms that:
- The Message class is correctly used in Result class as a List property
- The Result class properly instantiates Message objects in its constructor using the internal constructor
- Unit tests validate the Message integration by checking message count and body content
- The dot notation issue is properly addressed as Messages can be accessed via Result.Messages property

86-93: LGTM! Clean switch expression refactoring.
The switch expression refactoring improves code readability while maintaining the same functionality and proper error handling. The implementation correctly handles all AWS credential types and follows security best practices.

🛠️ Refactor suggestion
Add defensive programming measures in the constructor.
The current implementation has several potential issues:
- No null check for the input message parameter
- Direct reference assignment of the Attributes dictionary could allow external modifications
- No validation of required properties
internal Message(Amazon.SQS.Model.Message message)
{
+ if (message == null)
+ throw new ArgumentNullException(nameof(message));
+
- Attributes = message.Attributes;
+ Attributes = new Dictionary<string, string>(message.Attributes ?? new Dictionary<string, string>());
Body = message.Body;
MD5OfBody = message.MD5OfBody;
MD5OfMessageAttributes = message.MD5OfMessageAttributes;
MessageId = message.MessageId;
ReceiptHandle = message.ReceiptHandle;

🛠️ Refactor suggestion
Consider throwing for undefined regions instead of silent fallback.
The default case silently falls back to RegionEndpoint.EUNorth1 which could mask configuration errors. Consider throwing an exception to make region misconfiguration more visible:
return region switch
{
Region.EuNorth1 => RegionEndpoint.EUNorth1,
// ... other cases ...
Region.UsWest2 => RegionEndpoint.USWest2,
- _ => RegionEndpoint.EUNorth1,
+ _ => throw new InvalidEnumArgumentException($"Unsupported region: {region}")
