Implementing Deployment Markers in Application Insights

This post details the technical steps to enable and configure deployment markers in Application Insights. It explains how to modify project files to include `GenerateBuildInfoConfigFile` and `IncludeServerNameInBuildInfo` properties, and how to use an `AfterBuild` target to ensure the `BuildInfo.config` file is copied to the correct location (alongside `Web.config`). It also outlines the PowerShell command `Start-WebApplicationMonitoring` to enable monitoring and the subsequent creation of availability tests to visualize deployment markers alongside performance data.
