💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill addresses the issue of slow builds in MSBuild by optimizing parallelism, which can significantly speed up multi-project solutions and improve overall build performance.

Core Features & Use Cases

  • MSBuild Parallelism: Enhances build performance by utilizing multiple CPU cores.
  • Graph Build Mode: Implements graph-based scheduling for better build order and isolation.
  • Project Reference Optimization: Reduces unnecessary project references to streamline build processes.
  • BuildInParallel: Enables parallel building of projects within custom MSBuild targets.
  • Multi-threaded Tasks: Allows individual tasks to run multi-threaded within a project build.
  • Binlog Analysis: Provides tools for analyzing binlogs to diagnose build performance issues.
  • CI/CD Tips: Offers best practices for parallel builds in CI/CD pipelines.
  • Use Case: If you are experiencing slow builds, especially in large multi-project solutions, this Skill can help you identify bottlenecks and optimize your build process.

Quick Start

Analyze your build performance with the build-parallelism skill by running 'build-parallelism analyze build.binlog'.

Frequently Asked Questions about build-parallelism

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I optimize MSBuild parallelism for slow .NET builds?▼

You can speed up slow MSBuild builds by configuring the /maxcpucount parameter, enabling graph build mode for better scheduling, and reducing unnecessary project references to maximize parallel task execution across multiple CPU cores.

What is MSBuild graph build mode and when should I use it?▼

MSBuild graph build mode is a graph-based scheduling approach that improves build order and project isolation. Use it when experiencing slow builds in large multi-project .NET solutions to parallelize tasks more effectively.

How do I analyze binlogs to diagnose MSBuild build performance issues?▼

Analyze binlogs by running the command 'build-parallelism analyze build.binlog' to diagnose MSBuild build performance issues. This process identifies bottlenecks and evaluates parallel execution efficiency within your build pipeline.

Can I use parallel builds to optimize .NET CI/CD pipelines?▼

Yes, you can optimize .NET CI/CD pipelines by enabling MSBuild parallelism. This involves enabling BuildInParallel for custom targets, configuring multi-threaded tasks, and applying best practices to reduce overall pipeline execution time.

What is the best way to run multi-threaded tasks within an MSBuild project build?▼

The best way to run multi-threaded tasks is by enabling BuildInParallel within custom MSBuild targets. This allows individual tasks to run multi-threaded within a single project build, maximizing CPU core utilization and enhancing performance.
