• The update to xunit.v3 and the inclusion of PrivateAssets and IncludeAssets for xunit.runner.visualstudio appear aligned with our dependency isolation strategy. Please verify that these changes are fully compatible with our test infrastructure.

        <PackageReference Include="xunit.v3" Version="2.0.3" />

src/DynamoDb.DistributedLock/DynamoDb.DistributedLock.csproj:30

• The update of AWSSDK.DynamoDBv2 to version 4.0.1.8 should be verified against the features in use to ensure there are no breaking changes.

        <PackageReference Include="AWSSDK.DynamoDBv2" Version="4.0.1.8" />

src/DynamoDb.DistributedLock/DynamoDb.DistributedLock.csproj:32

• The update to Microsoft.Extensions packages (Binder, DependencyInjection, Options) to version 9.0.6 is consistent; please confirm that any related service configurations accommodate these version bumps.

        <PackageReference Include="Microsoft.Extensions.Configuration.Binder" Version="9.0.6" />
