I'm finding my Output Window's content quite unpleasant to use, as the window is about 90% full of debug lines from IIS Express and from Application Insights. Ideally I would like to filter the Debug sources that write to that window, but maybe I can configure either source to not write so much debug data, e.g. maybe set a higher minimum level like Error vs. what looks like Trace, or at least Info.
What can I do so I can more easily see my own debug statements and important stuff, like WPF binding errors?
I've found an excellent solution for most unwanted info in the Output Window in this answer, but there is still a lot of clutter from ApplicationInsights. Is there no way to configure this locally to only write at level Error?
there's no error level concept for ApplicationInsights output all up (some things like custom events, metrics, etc, don't have the concept of an error level).
if you want to disable the output, you can either set DeveloperMode to false, or use TelemetryDebugWriter.IsTracingDisabled = true; to disable output.
(disabling output will make any of the application insights tools in visual studio while debugging no longer function, though. the AI VS extension is watching the output window for those events to power content in Diagnostics Tools window, debug search, and local CodeLens scenarios)
