SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

MSBuild Server for CLI caching addresses slow CLI builds by turning on a long-lived MSBuild process that caches evaluation results, resolved references, and other state across builds, reducing startup time and incremental build overhead.

Core Features & Use Cases

Long-lived MSBuild server that persists across invocations.
Caches evaluation results and dependencies to speed up subsequent builds.
Reduces build times for large repos with many projects, and benefits CI pipelines with repeated builds.
Not activate for IDE-based builds, since IDEs typically manage their own long-lived processes.

Quick Start

Enable the server by setting MSBUILDUSESERVER=1 in your environment and run a few dotnet build commands to observe caching benefits.

FAQPage Schema

How do I speed up dotnet build for large solutions?▼

To speed up dotnet build, set MSBUILDUSESERVER=1 in your environment to activate a persistent MSBuild server that caches evaluation results and state across builds.

How does MSBuild server caching improve CLI build performance?▼

MSBuild server caching improves CLI build performance by maintaining a long-lived MSBuild process that persists evaluation results and dependencies, avoiding repeated startup and resolution overhead across builds.

Does the MSBuild server work with IDE-based builds?▼

No, the MSBuild server does not apply to IDE-based builds, since IDEs typically manage their own long-lived build processes and caching mechanisms.

Can I use MSBuild server caching in CI pipelines with frequent builds?▼

Yes, MSBuild server caching benefits CI pipelines with repeated builds by caching state and evaluation results, significantly reducing build times for large solutions.

What is the best way to reduce dotnet build startup time?▼

The best way to reduce dotnet build startup time is enabling a long-lived MSBuild server via MSBUILDUSESERVER=1, which caches state and evaluation results across multiple builds.

When should I not use a persistent MSBuild server?▼

You should not use a persistent MSBuild server for IDE-based builds or scenarios without frequent CLI builds, as the caching benefits target repeated dotnet build invocations.
