System.ClientModel_1.15.0

1.15.0 (2026-07-30)

Features Added

• Added sealed, one-shot AsyncStreamingClientResult<T> for asynchronous streaming responses, with factories for custom producers, server-sent events, and newline-delimited JSON.

Bugs Fixed

• Fixed an issue where response content logging could emit more bytes than were actually read when a non-buffered (streaming) response was read into a buffer larger than the response body. Previously, when the read began at offset 0, MessageLoggingPolicy logged the entire caller-supplied buffer — including the bytes past the response payload, which for a pooled buffer contain unrelated in-process content — and the configured MessageContentSizeLimit was not applied. Only the bytes that were read are now logged. (#61399)
