## What it is
A structured logger for MSBuild that records executed targets, tasks, properties, and item values into a portable binary format (*.binlog). It ships with a rich interactive log viewer (WPF on Windows, Avalonia on Mac/Linux) to simplify build investigations.

## Use cases
- investigate why my msbuild build is slow
- view msbuild binlog files interactively
- debug build errors with structured target and task logs
- record and share build logs for CI troubleshooting
- inspect msbuild property and item values during a build
- analyze dotnet build output in a searchable viewer

## When to choose
- you build .NET projects with MSBuild or dotnet build and need to diagnose build issues
- you need a portable, structured build log format to share with teammates or CI
- you want a cross-platform GUI to explore large, verbose build logs

## When to avoid
- you need logging for build systems other than MSBuild (e.g., Make, Gradle, Bazel)
- you only need simple console build output without structured analysis
- you are not working in the .NET/MSBuild ecosystem

## Facets
- artifact type: application
- maturity: active
- function: logging, developer-tools, gui, cli, serialization
- domain: developer-tools, documentation
- platform: windows, cross-platform, dotnet
- tags: msbuild, binlog, build-log, log-viewer, avalonia, wpf, csharp, nuget, command-line, macos, linux, desktop
