MSBuild Binlog Analyzer for VS Code integrates Copilot for build log analysis
Key points
- New VS Code extension for MSBuild binary log analysis.
- Integrates GitHub Copilot Chat for interactive diagnosis.
- Identifies build failures, performance issues, and changes.
- Eliminates need for separate tools or manual log inspection.
New Tool for MSBuild Log Analysis
Microsoft introduced the MSBuild Binlog Analyzer for VS Code, now available in Preview on the Visual Studio Marketplace. This extension aims to simplify the process of understanding MSBuild binary logs (.binlog files) by bringing analysis capabilities directly into the VS Code environment.
Copilot Integration for Diagnostics
The core feature of the Binlog Analyzer is its integration with GitHub Copilot Chat. Users can query Copilot directly within VS Code to get plain-language explanations for build failures, identify root causes, and receive suggestions for fixes. This integration automates the diagnostic process that previously required manual inspection of complex log files.
Addressing Common Build Problems
The extension provides solutions for common developer challenges, such as diagnosing why a build failed, identifying the slowest targets and tasks affecting build time, and comparing two builds to pinpoint performance regressions or other changes. It also helps determine if incremental builds are functioning as expected by showing which targets rebuilt and why.
Underlying Technology
The Binlog Analyzer pairs with a .NET global-tool MCP server, Microsoft.AITools.BinlogMcp. This server exposes build-analysis tools over the Model Context Protocol, which Copilot uses to ground its answers in the actual log data. The server is automatically installed upon the extension's first use, requiring no manual setup.
Installation and Usage
To use the extension, developers need VS Code 1.99+, GitHub Copilot, and the .NET SDK. After installation from the Marketplace, .binlog files can be loaded via the Command Palette, by building and capturing a binlog in one step, or by opening from the Structured Log Viewer. Users can then interact with Copilot Chat using the @binlog command to ask questions about their build logs.

Reporting from
Microsoft released the MSBuild Binlog Analyzer for VS Code, a new extension that integrates GitHub Copilot Chat to analyze MSBuild binary logs directly within the editor. This tool helps developers diagnose build failures, identify performance bottlenecks, and compare build changes without leaving their development environment.
