Decision brief

BuildXL accelerates build processes using sandboxing for clean builds, supports coreclr and CLI on multiple OSes.

Good fit when

  • You are working with C# projects and need fast, reliable build times across different operating systems
  • Your project requires a sanitized build environment to prevent build discrepancies and bugs caused by system differences

Avoid when

  • If your project is not in C# or dotnet ecosystem, as BuildXL is tightly integrated with dotnet components like coreclr
  • When strict real-time dependency tracking between different languages and tools is required that goes beyond filesystem boundaries
