Use when wiring the host, DI, modules, startup steps or the module-to-database topology (Pragmatic.Composition, PragmaticApp, IPragmaticBuilder, [Service], [Decorator], [Module], [Include], [StartupStep]).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Pragmatic Use Composition **Covers:** Bootstrap host, DI, modules, and startup pipeline with Pragmatic.Composition consumed from NuGet. [Service], [Decorator], [Module], [Include], [StartupStep], IPragmaticBuilder, PragmaticApp. `Pragmatic.Composition` is the hosting and DI layer. It works by **composition by presence**: whatever you reference (NuGet package or boundary library) is discovered by the source generator and activated. You do not write manual `services.Add*()` calls for Pragmatic features. ## When to use - You are creating the host (`Program.cs`) of a Pragmatic app. - You are registering custom services, decorators, modules, or startup steps. - You are choosing the infrastructure strategy (auth, storage, jobs) via `Use*()`. For structuring into modules/boundaries and architectural decisions: `pragmatic-architecture`. ## Packages ```xml <PackageReference Include="Pragmatic.Abstractions" Version="1.0.0-alpha.3" /> <!-- attributes --> <PackageReference Include="Pragmatic.Composition" Version="1.0.0-alpha.3" /> <!-- host runtime --> <PackageReference Include="Pragmatic.SourceGenerator" Version="1.0.0-alpha.3"> …

How to install
mdr add pragmatic-design/pragmatic.design/pragmatic-use-composition@sha256:aa2d53f84766bedaThe line at the top of this page pins the label git:20261017.dc88d60, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
