msbuild-server
Guide for using MSBuild Server to improve CLI build performance. Activate when developers report slow incremental builds from the command line, or when CLI builds are noticeably slower than IDE builds. Covers MSBUILDUSESERVER=1 environment variable for persistent server-based caching. Do not activate for IDE-based builds (Visual Studio already uses a long-lived process).
npx skills add dotnet/skills --skill msbuild-server --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

# MSBuild Server for CLI Caching Use the MSBuild Server to cache evaluation results across CLI builds, matching the performance advantage Visual Studio gets from its long-lived MSBuild process. ## When to Use - Small incremental builds from CLI (`dotnet build`) are slower than expected - Developers notice that VS builds are faster than CLI builds for the same project - CI agents run many sequential builds of the same repo ## When Not to Use - IDE-based builds (Visual Studio already uses a long-lived MSBuild process) - One-off builds where cold-start overhead is acceptable - Build correctness issues are suspected (disable the server to isolate the problem) ## Inputs | Input | Required | Description | |-------|----------|-------------| | Shell context | No | The shell where the environment variable will be set (bash, PowerShell, or Windows persistent) | ## Workflow ### Step 1: Confirm CLI context Verify the developer is building from the command line (`dotnet build`), not from Visual Studio or another IDE. The MSBuild Server provides no benefit inside an IDE. ### Step 2: Set the environment variable ```bash # Bash / CI export MSBUILDUSESERVER=1 # PowerShell $env:MSBUILDUSESERVER = "1

What does the msbuild-server skill do?
Guide for using MSBuild Server to improve CLI build performance. Activate when developers report slow incremental builds from the command line, or when CLI builds are noticeably slower than IDE builds. Covers MSBUILDUSESERVER=1 environment variable for persistent server-based caching. Do not activate for IDE-based builds (Visual Studio already uses a long-lived process).
How do I install it?
Run `npx skills add dotnet/skills --skill msbuild-server --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From dotnet/skills, a repository with 4,927 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
