Reduce allocations when Activity is enabled - #11020
Merged
Merged
Conversation
- Remove string allocations caused by DiagnosticSource.Stop/StartActivity - Pass the HttpContext directly as the object for StartActivity and StopActivity to avoid the anonymous object allocation. - Though it's a bit ugly, added an HttpContext property to DefaultHttpContext to avoid breaking back-compat (which had to do reflection to get the HttpContext property anyways)

cc @lmolkova @SergeyKanzhelev as an FYI, this should be non breaking though. |

I like this and we may be able to update listener in time for 3.0 to support it. But it is breaking (i.e. there is no HttpContext property on HttpContext type), everyone who attempts to get it will fail.
