Azure/azure-sdk-for-net System.ClientModel

1.10.0 (2026-03-16)

Added JsonPatch.EnumerateArray method that iterates over JSON array elements at a specified path, yielding each element as raw UTF-8 bytes.
Added CollectionResult<T>.FromPages and AsyncCollectionResult<T>.FromPages static factory methods that create collection result instances from pre-existing pages of values for testing.
Added IsReadOnly property to ClientPipelineOptions and ClientLoggingOptions so callers can check whether options can still be modified without catching an exception.
Added Clone() method to ClientPipelineOptions and ClientLoggingOptions that creates a new mutable instance from an existing instance that may be read-only.
Added ConfigurationSchema.json to the NuGet package via the MSBuild JsonSchemaSegment feature, enabling automatic JSON IntelliSense and validation for appsettings.json when configuring System.ClientModel-based clients.
Updated BCL dependencies to 10.x.

Fixed implicit conversion operator for ClientResult<T> to not throw exceptions on null inputs per Framework Design Guidelines. Null inputs now return default.

Added nullability annotation to the ClientResult<T> implicit conversion operator parameter to indicate that null is a valid input. This change was made because throwing exceptions from implicit conversions violates the Framework Design Guidelines.
