don't forget other snippets included: multiple functions to change console colors (aka Console.SetRed() / Blue / Green / etc), get all processes in OS (aka Processes.Google / notepad / vscode / etc). it is super useless

✅ Dependency injection
so now you invert of control dependencies to somewhere else. In real situations we have some systems to control our dependencies, which injects everything you need.

✅ Dependency injection
now let's do some DI. Instead of controlling all dependencies inside of your SolarPanelService you tell: "Yeah, I have some things which I depends on (and they are also depends on others)", so you need to get them for your service, and now we call constructor: 
public class SolarPanelService : ISolarPanelService
{
+    private readonly IWeatherService _weatherService;

+    public SolarPanelService(IWeatherService weather)
+    {
+        _weatherService = weather;
+    }

    public bool CanActivate() => _weatherService.GetCurrentWeather() == Weather.Sunny;
}
public class SolarPanelService : ISolarPanelService
{
+    private readonly IWeatherService _weatherService;

+    public SolarPanelService(IWeatherService weather)
+    {
+        _weatherService = weather;
+    }

    public bool CanActivate() => _weatherService.GetCurrentWeather() == Weather.Sunny;
}

✅ Dependency injection
DI aka dependency injection is all about IoC (inversion of control). Imaginary a situation when you are creating solar panels service. It needs to know what is the current weather. You have your weather service: 
public enum Weather
{
    Sunny, 
    Rainy, 
};

public class WeatherService : IWeatherService 
{
    public Weather GetCurrentWeather() => Weather.Sunny;
}
public enum Weather
{
    Sunny, 
    Rainy, 
};

public class WeatherService : IWeatherService 
{
    public Weather GetCurrentWeather() => Weather.Sunny;
}
so you can normally use it for your solar panel service: 
public class SolarPanelService : ISolarPanelService
{
-   private readonly IWeatherService _weatherService = new WeatherService();

    public bool CanActivate() => _weatherService.GetCurrentWeather() == Weather.Sunny;
}
public class SolarPanelService : ISolarPanelService
{
-   private readonly IWeatherService _weatherService = new WeatherService();

    public bool CanActivate() => _weatherService.GetCurrentWeather() == Weather.Sunny;
}
so, now take a look at this line 
- private readonly IWeatherService _weatherService = new WeatherService(); 
- private readonly IWeatherService _weatherService = new WeatherService();
as you see your are creating your WeatherService inside of another service. And now imagine that your boss told you to add logging into weather, then to add cache system, then to add email for some reason (idk, maybe boss wants to send weather email, XD). So, it becomes more and more complex 
- private readonly ILogger _logs = new Logger();
- private readonly ICache _cache = new Cache();
- private readonly IEmail _email = new Email();

- private readonly IWeatherService _weatherService = new WeatherService(_logs, _cache, _email, ...);
- private readonly ILogger _logs = new Logger();
- private readonly ICache _cache = new Cache();
- private readonly IEmail _email = new Email();

- private readonly IWeatherService _weatherService = new WeatherService(_logs, _cache, _email, ...);
so it is super complex now...
