Mediarq.HealthChecks

Catches a missing or ambiguous handler before it becomes a HandlerNotFoundException at the first dispatch in production: an IHealthCheck for your /health endpoint, plus an optional check that runs once at host startup and fails the app fast.

dotnet add package Mediarq.HealthChecks

Usage

builder.Services.AddHealthChecks()
    .AddMediarqHandlerRegistrationCheck(assemblies: typeof(Program).Assembly);

Exposes it the usual way:

app.MapHealthChecks("/health");

Healthy when every ICommand/IQuery closed type discovered in assemblies resolves to exactly one registered IRequestHandler<TRequest, TResponse>; otherwise Unhealthy, with the offending types and their handler counts (0 = missing, 2+ = ambiguous) in the result's Data.

Fail fast at startup

builder.Services.AddMediarqHandlerValidationOnStartup(typeof(Program).Assembly);

Runs the same check once, synchronously, as part of host startup — a misconfiguration throws InvalidOperationException and the app never starts accepting traffic, instead of surfacing on whichever request happens to hit the broken handler first.

assemblies defaults to the entry assembly when omitted; pass every assembly that declares commands/queries or handlers explicitly in a modular app.
