How to add health checks to .Net core Background service

Question

I am having a .net core 2.1 Background service application which is subscribed to a queue in Microsoft Azure Service bus. It has some logic and it calls to an api over http. I would like to create a health check for this service. Could anyone please help me out?

Answer 1

Official HealthCheck premiere was in 2.2:

Health checks in ASP.NET Core 2.2:

https://learn.microsoft.com/en-us/aspnet/core/host-and-deploy/health-checks?view=aspnetcore-2.2

For 5.0:

https://learn.microsoft.com/en-us/aspnet/core/host-and-deploy/health-checks?view=aspnetcore-5.0

If you have to stay on 2.1 than I suggest to create a special endpoint for it.
