Healthie.NET.DependencyInjection

▶ Live demo — healthie.compiletheory.com — a read-only Healthie.NET dashboard watching real status pages (Anthropic, OpenAI, GitHub, Cloudflare, and more), built from these packages.

DI registration and the built-in TimerPulseScheduler for Healthie.NET. This package scans assemblies for PulseChecker implementations, registers them as singletons, and provides a zero-dependency PeriodicTimer-based scheduler.

Installation

dotnet add package Healthie.NET.DependencyInjection

Usage

using Healthie.DependencyInjection;

var builder = WebApplication.CreateBuilder(args);

// Scans for PulseChecker implementations and registers the built-in PeriodicTimer
// scheduler and in-memory state provider.
builder.Services.AddHealthie(typeof(Program).Assembly);

var app = builder.Build();
app.Run();

With custom options:

builder.Services.AddHealthie(
    options => options.MaxHistoryLength = 10,
    typeof(Program).Assembly);

Key Types

Type	Description
`StartupExtensions.AddHealthie()`	Registers core services and scans assemblies for pulse checkers.
`TimerPulseScheduler`	Built-in `IPulseScheduler` using `PeriodicTimer`. Zero external dependencies.

What It Registers

All discovered IPulseChecker implementations as singletons
IPulsesScheduler / PulsesScheduler as a hosted service
IPulseScheduler / TimerPulseScheduler as the default scheduler
HealthieOptions as a singleton
StateProviderInitializationService as a hosted service

Twenty packages was too many, and two of them had no business being separate. This release fixes
that without breaking anything: **an application on 4.0.0 upgrades by changing nothing.**

### Added

- **`Healthie.NET`**, the package to install first. It carries no code of its own, only a dependency
on `Healthie.NET.DependencyInjection`, so it is one install and one dependency rather than a
bundle -- no provider, scheduler or UI framework arrives with it. The name people guess did not
exist before, and the actual entry point was called `DependencyInjection`, which reads like
plumbing rather than the way in.
- **Uptime reporting and leader election are in the core package.** `AddHealthieUptime()` and
`AddHealthieLeaderElection()` need nothing else installed. Both stay opt-in: nothing runs until
you call them.

### Deprecated

- **`Healthie.NET.Uptime`** and **`Healthie.NET.LeaderElection`**. Neither carried a third-party
dependency, so keeping them separate cost two installs and saved nothing -- the provider packages
exist to keep Npgsql or Temporalio off machines that do not use them, and these two were not
providers.

**Nothing breaks.** Both packages are still published, now as assemblies of type forwards, so an
application that references either keeps compiling *and* keeps running untouched. That is what
makes this a minor release: moving a type between assemblies is a binary break the compiler cannot
see, because source keeps building and only the runtime finds out. Remove the reference whenever it
suits you; neither package will gain features.

### Fixed

- **The sample Dockerfiles took their .NET base images by mutable tag.** A tag is a different image
next week, so the build that passed review is not the build that ships. Both are pinned by digest,
which Dependabot updates the way it updates a package version. Closes four OpenSSF Scorecard
*Pinned-Dependencies* findings.

### Security

- **An Azure CosmosDB key committed in May 2025 was confirmed dead and the alert closed.** It had
already been removed from the working tree; the account it belonged to no longer exists in the
owning tenant, verified by enumerating every Cosmos account across that tenant's subscriptions, so
the key authenticates to nothing. It remains in history at `ee0c78e`, inert.
- **Stray screenshots can no longer be committed.** Root-level PNGs are ignored, scoped to the root
so the images the docs and samples genuinely ship are untouched.
