PID file manager

Takes care of creating and deleting PID file in ASP.Net Core applications. Mechanics on which the library is based are described in this article. You can also find there information on how to create a systemd service that creates /var/run/yourapp/ directory with necessary write permissions for you.


  1. Install nuget package:
dotnet add package Rychusoft.PidFileManager
  1. In the Startup.cs add services.AddPidFileHostedService(Configuration.GetSection("PidFileOptions")); to the ConfigureServices() method:
public class Startup

    public void ConfigureServices(IServiceCollection services)


  1. In the appsettings.json add new section - note that the user under which your app is run need to have a privilages to write to this path:
"PidFileOptions": {
  "PidFilePath": "/var/run/yourapp/yourapp.pid"
  1. In the appsettings.Development.json add new section that will disable creating PID file when running in development environment (e.g., from Visual Studio):
"PidFileOptions": {
  "IsDisabled": true


  1. You can configure the service as shown above, in the Usage section, by calling services.AddPidFileHostedService(Configuration.GetSection("PidFileOptions"));. Possible appsettings properties:
  • PidFilePath - string - full file path where the PID file will be created
  • IsDisabled - bool - if set to true then service will not create a PID file. Useful for disabling the service in development environment.
  1. You can configure the service by providing a lambda expression that yields an instance of the options class:
services.AddPidFileHostedService(options =>
    options.PidFilePath = "/var/run/yourapp/yourapp.pid";
    options.IsDisabled = false;
