The only number you'll need to dial when things go south.

Hotline is a middleware component for ASP.NET Core that enabled you to report unhandled exceptions to external error tracking services.

You can obtain the package relevant to the error reporting service you're using from NuGet:

We'll configure Hotline for Sentry in this introduction. Sentry requires a DSN to make a connection; add the following to your appSettings.json:

  "Sentry": {
    "Dsn": "{your_DSN_here}"
  } 

Now we'll call Configure<SentryOptions> to wire up the configuration the middleware requires in Startup.cs:

services.Configure<SentryOptions>(Configuration.GetSection("Sentry"));

Register the SentryHotline provider with the DI container:

services.AddScoped<IHotline, SentryHotline>();

Then finally, install the middleware:

app.UseHotline();

Make sure the Hotline middleware component added to the pipeline, so definitely before app.UseMvc() and any other middleware you are running.

And that's all - any unhandled exceptions will now be automatically reported to Sentry in full.

Any and all contributions, new providers for Hotline, bugfixes, features, are welcome. It is preferred contributions follow the netcore code style guidelines as well as the relevant C# conventions.
