Dut00.AppInfo

Adds an /appinfo endpoint to ASP.NET Core applications. It returns JSON describing the running application.

using Dut00.AppInfo;

builder.Services.AddAppInfo()
    .WithOwner("red_team@company.com")
    .WithProperty("Team", "red")
    .WithProperty("StartedBy", sp => sp.GetRequiredService<IMyService>().User);

var app = builder.Build();
app.MapAppInfo(); // GET /appinfo

{
  "ApplicationName": "Company.Billing.Api",
  "Version": "1.0.5.0",
  "Environment": "Stage",
  "IsProduction": false,
  "Owner": "red_team@company.com",
  "Team": "red",
  "StartedBy": "deploy-bot"
}

API

Member Adds
AddAppInfo(o => ...) ApplicationName, Version (entry assembly), Environment, IsProduction
WithOwner(owner) Owner
WithProperty(key, value) A custom key with a constant value
WithProperty(key, sp => ...) A custom key computed on every request; the factory may resolve scoped services
WithContributor<T>() Everything a custom IAppInfoContributor writes
MapAppInfo(pattern = "/appinfo") The GET endpoint; returns IEndpointConventionBuilder

To write a constant null, cast it: WithProperty("Key", (object?)null). A plain null binds to the factory overload and throws.

Keys appear in registration order. Use o.KeyNamingPolicy = JsonNamingPolicy.CamelCase (or any JsonNamingPolicy) to change the key format; o.JsonSerializerOptions gives full control over value serialization.

More fields come from the extension packages: Dut00.AppInfo.Configuration, Dut00.AppInfo.Environment and Dut00.AppInfo.ConnectionStrings.

Custom contributors

public sealed class GitInfoContributor : IAppInfoContributor
{
    public ValueTask ContributeAsync(AppInfoContext context, CancellationToken cancellationToken)
    {
        context.Set("Commit", System.Environment.GetEnvironmentVariable("GIT_COMMIT"));
        return ValueTask.CompletedTask;
    }
}

builder.Services.AddAppInfo().WithContributor<GitInfoContributor>();

The endpoint is open by default and may expose internal details. Protect it, for example with app.MapAppInfo().RequireAuthorization().
