If you’re unfamiliar with Prometheus, in a nutshell it’s a time-series database for storing metrics, like counters and histograms. Applications that store their metrics in Prometheus typically use a popular Prometheus client as part of the integration. Now that OpenTelemetry is a graduated CNCF project, many companies are now increasingly looking to move to OpenTelemetry to add more signals beyond metrics to their observability architecture. Logs and traces are popular additions for getting further insight into how applications behave. Profiles are also starting to become a popular fourth telemetry signal for even deeper understanding.https://opentelemetry.io/blog/2026/dual-dotnet-metrics-export-with-otlp-and-prometheus/https://opentelemetry.io/blog/2026/dual-dotnet-metrics-export-with-otlp-and-prometheus/Fri, 18 Sep 2026 22:17:34 GMTobservabilitydotnetopentelemetryprometheushttps://cakebuild.net/blog/2026/09/cake-v6.3.0-releasedhttps://cakebuild.net/blog/2026/09/cake-v6.3.0-releasedWed, 16 Sep 2026 15:50:33 GMTdotnetcakebuildcsharpBoost your application quality by learning how to analyze our test coverage and improve it using Visual Studio features.https://devblogs.microsoft.com/visualstudio/today-i-will-improve-test-coverage/https://devblogs.microsoft.com/visualstudio/today-i-will-improve-test-coverage/Tue, 15 Sep 2026 23:12:36 GMTvisualstudiotestingcoverageaccessibilityASP.NET Core treats files in wwwroot as public static content, but occasionally applications create files there that should only be available to authorized users.
