+Since version 3.1.0 you can also inject `WMIWatcher` into your classes using Microsoft DI implementation. Just like you can do with `WMIHelper`:
+
+```C#
+    .ConfigureServices((hostContext, services) =>
+    {
+        services.AddHostedService<Worker>();
+        services.AddSingleton<IWMIWatcher, WMIWatcher>();
+    });
+```
+
+**NOTE**: If you inject `WMIWatcher` with the empty constructor you will have to call the `Initialize` method so you can correctly initialize `WMIWatcher` with the desired parameters. Otherwise it will not work
+
+```C#
+    public class Worker : BackgroundService
+    {
+        private readonly IWMIWatcher _watcher;
+
+        public Worker(IWMIHelper helper, IWMIWatcher watcher)

 ## Methods
 
 Since version 1.3.0 ORMi supports method working in a quite simple way. WMI defines two types of methods: Instance methods and Static methods.
