on GitHub

1.52.0 (2026-03-23)

Features Added

• Added IndonesiaCentral, NewZealandNorth, and MalaysiaWest locations to AzureLocation struct.
• Added a JSON schema segment to the NuGet package that provides IntelliSense and validation for AzureClients configuration in appsettings.json, including Retry and Diagnostics options.

Bugs Fixed

• Fixed implicit conversion operators to not throw exceptions on null inputs per Framework Design Guidelines. Operators now return safe defaults: null for reference types, default for value types.
• Fixed RequestContent.Dispose() to be idempotent and thread-safe, preventing ArrayPool buffers from being returned multiple times when disposed concurrently or repeatedly.
• Fixed HttpClientTransport to correctly set the Host header on outgoing requests when explicitly specified, rather than falling through to TryAddWithoutValidation.

Breaking Changes

• Added nullability annotations to implicit conversion operator parameters for Response<T>, AzureLocation, ContentType, ResourceType, RequestContent, and DynamicData to indicate that null is a valid input. This change was made because throwing exceptions from implicit conversions violates the Framework Design Guidelines.
• Updated RequestContent implicit conversion operators to return nullable RequestContent? to accurately reflect that null inputs produce null outputs.
