4-4: Consider addressing the pragma directive inconsistency.The pragma directive is disabling warning ECS0200, which corresponds to
PreferReadonlyOverConst. This creates an inconsistency where the class is not following its own advice. Consider one of the following options:
- Remove the pragma directive and change the constants to readonly fields.
- If const is required for performance reasons, add a comment explaining why the warning is disabled and why const is preferred in this specific case.
Example fix for option 1:
- #pragma warning disable ECS0200 // Consider using readonly instead of const for better flexibility - internal static class DiagnosticIds + internal static class DiagnosticIds { - internal const string PreferImplicitlyTypedLocalVariables = "ECS0100"; + internal static readonly string PreferImplicitlyTypedLocalVariables = "ECS0100"; // Apply similar changes to all other fields }Example fix for option 2:
+ // Const is used here for performance reasons as these values are compile-time constants. + // The performance benefit outweighs the flexibility of readonly in this specific case. #pragma warning disable ECS0200 // Consider using readonly instead of const for better flexibility

20-20: LGTM: New constant follows established conventions.The addition of
MinimizeDuplicateInitializationLogicconstant is consistent with the existing code structure and naming conventions. The diagnostic ID "ECS1400" follows the established pattern.Directory.Packages.props (1)
19-19: Verify the necessity and impact of adding Microsoft.Bcl.HashCode package.The addition of the Microsoft.Bcl.HashCode package (version 1.1.1) aligns with the PR objective of minimizing initialization logic, as it provides efficient hash code generation which can be useful for optimizing object comparisons and collections.
However, please consider the following points:
Ensure that this package is actually needed for the implementation of Item 14. If it's not directly related to minimizing initialization logic, consider moving this change to a separate PR.
The package is placed in the "Public APIs" section. According to the comment, these packages impact SDK compatibility. Verify if this is the correct placement and if there are any potential compatibility issues with adding this package.
Check if version 1.1.1 is the most appropriate version to use. It's the latest stable version as of now, but ensure it meets your project's stability and compatibility requirements.
To help verify the usage and necessity of this package, you can run the following script:
This will help identify where the new HashCode functionality might be used in the codebase, confirming its necessity for the PR objective.
✅ Verification successful
Verified the addition of Microsoft.Bcl.HashCode package is necessary.
The
HashCodestruct is utilized inMinimizeDuplicateInitializationLogicAnalyzer.cs, confirming that the inclusion of the Microsoft.Bcl.HashCode package (version 1.1.1) is required for this functionality.

34-34: Approve package addition with suggestionsThe addition of the
Microsoft.Bcl.HashCodepackage is appropriate for a .NET Standard 2.0 project. This package provides a polyfill for theHashCodestruct, which can be useful for consistent hash code generation across different .NET versions.However, I have a few suggestions and questions:
Consider specifying a version for the package reference to ensure consistency and avoid unexpected behavior from future updates.
Could you clarify how this package will be used in the context of minimizing initialization logic (as mentioned in the PR title)? It would be helpful to understand the connection between this change and the PR objective.
I recommend updating the PR description or adding a comment in the code to explain the purpose of this change and how it relates to the broader goal of minimizing initialization logic.
To ensure this package addition is justified, let's check if there are any new usages of the
HashCodetype in the project:✅ Verification successful
Package Addition Verified and Approved with Recommendations
The usage of the
Microsoft.Bcl.HashCodepackage has been confirmed within theMinimizeDuplicateInitializationLogicAnalyzer.csfile. Specifically, theHashCodestruct is utilized in theGetHashCodemethod to efficiently aggregate hash codes, aligning with the project's goal of minimizing initialization logic.Recommendations:
Specify Package Version:
- To ensure consistency and prevent unexpected behavior from future updates, please specify a version for the
Microsoft.Bcl.HashCodepackage reference.Clarify PR Objective Connection:
- While the package usage aligns with minimizing initialization logic, adding a brief explanation in the PR description or within the code comments would enhance clarity on how this addition contributes to the overall objective.

607-856: Summary: Increased flexibility in diagnostic rule applicationThe changes in this file consistently allow for the suppression of certain diagnostic rules (RCS1031, RCS1031FadeOut, and RS1030). While this provides more flexibility in code style and analyzer behavior, it's crucial to use these suppressions judiciously.
Consider the following recommendations:
- Document the reasons for allowing suppressions, either in comments or in a separate coding guidelines document.
- Regularly review the use of these suppressions to ensure they're not being overused or causing unintended consequences.
- For performance-critical rules like RS1030, establish a process for reviewing and approving suppressions before they're applied.
These changes can be beneficial if managed properly, but they also introduce the potential for inconsistency or performance issues if not used carefully.

856-856: Approved with caution: Be aware of performance implicationsThe change to allow suppression of RS1030 (Do not invoke Compilation.GetSemanticModel() method within a diagnostic analyzer) is approved. However, it's important to note that this rule exists for performance reasons, and suppressing it could potentially lead to performance issues in diagnostic analyzers.
Please ensure that suppressions of this rule are used judiciously and only in cases where it's absolutely necessary. Consider adding a comment explaining the rationale:
- {Id: RS1030, Title: Do not invoke Compilation.GetSemanticModel() method within a diagnostic analyzer, Category: MicrosoftCodeAnalysisCorrectness, DefaultSeverity: Warning, IsEnabledByDefault: true, EffectiveSeverities: [Error], IsEverSuppressed: true} # Suppression allowed for specific cases where GetSemanticModel() is necessary and performance impact is minimalAdditionally, it would be beneficial to verify the usage of this suppression across the codebase:
This will help ensure that the suppression is not overused.

This pull request introduces a new Roslyn analyzer to enforce best practices for C# constructors. The analyzer identifies cases where a constructor contains duplicate initialization logic as another constructor.
