chore: Add comparison to Value

[askpt]

Signed-off-by: André Silva [email protected]

This PR

This pull request introduces enhancements to the Value class in the OpenFeature.Model namespace, ensuring better equality handling, and updates dependencies to include Microsoft.Bcl.HashCode. The most significant changes include implementing equality comparison for Value, adding hash code generation, and updating project files to include the new dependency.

Enhancements to Value class:

• src/OpenFeature/Model/Value.cs: The Value class now implements IEquatable<Value> and includes methods for equality comparison (Equals, ==, !=), hash code generation (GetHashCode), and internal helpers for comparing complex types like structures and lists. This ensures more robust and consistent equality checks. [1] [2]

Dependency updates:

• Directory.Packages.props: Added Microsoft.Bcl.HashCode as a dependency for hash code generation. Other package references were reformatted for consistency.
• src/OpenFeature/OpenFeature.csproj: Included Microsoft.Bcl.HashCode for specific target frameworks (net462 and netstandard2.0).

Notes

This implementation is necessary for the comparison in the MultiProvider. See: #488 (comment)

Great question. It is used to generate the HashCode for the IEquatable override. Check the documentation here: https://learn.microsoft.com/en-us/dotnet/api/system.hashcode?view=net-9.0
