[bakgerman]

Added render for (Core only) HttpContext.Connection.Id
Added render for both Core and Framework for HttpResponse HeadersWritten(Framework) and HasStarted(Core) named AspNetResponseHeadersWrittenLayoutRenderer
Added public bool Verbose option for ClientCertificate renderer
Added extension methods for HttpContext for TryGetConnection and TryGetWebSocket

Though it seems tempting, then you cannot repair past mistakes unless doing a major-version-bump (Ex. NLog.Web v6)

Please revert class-renames, then we can make an issue about fixing this with v6.

[bakgerman]

Yes I will revert the class names commits and keep them local.

w3c layout unit test fail again, but this should be able to be pulled successfully.

[bakgerman]

After this I cannot think of more NLog.Web layout renderers. Hopefully someone will find them useful. We are not trying to be equal to Visual Studio debugger in NLog, but I just try to find properties of HttpContext that we did not have already, that might be necessary to be logged.

Thank you for nudging. Have tried to make W3CLoggerLayoutTests more stable, by replacing finalizer with dispose and forced AccurateUtcTimeSource

Have now merged #813 that will ensure future class-names will always end with "LayoutRenderer" (And matches their type-alias)
