+title: Dependency Injection
+description: How to make use of dependency injection in CounterStrikeSharp
+sidebar:
+  order: 1
+---
+
+`CounterStrikeSharp` uses a standard <a href="https://learn.microsoft.com/en-us/aspnet/core/fundamentals/dependency-injection?view=aspnetcore-8.0" target="_blank">`IServiceCollection`</a> to allow for dependency injection in plugins.
+
+There are a handful of standard services that are predefined for you (`ILogger` for logging for instance), with more to come in the future. To add your own scoped & singleton services to the container, you can create a new class that implements the `IPluginServiceCollection<T>` interface for your plugin.
+
+```csharp
+public class TestPlugin : BasePlugin
+{
+  // Plugin code...
+}
+
+public class TestPluginServiceCollection : IPluginServiceCollection<TestPlugin>
+{
+    public void ConfigureServices(IServiceCollection serviceCollection)
+    {
+        serviceCollection.AddScoped<ExampleInjectedClass>();
+        serviceCollection.AddLogging(builder => ...);
+    }
+}
+```
+
+CounterStrikeSharp will search your assembly for any implementations of `IPlugin` and then any implementations of `IPluginServiceCollection<T>` where `T` is your plugin. It will then configure the service provider and then request a singleton instance of your plugin before proceeding to the load step.
+
+In this way, any dependencies that are listed in your plugin class constructor will automatically get injected at instantation time (before load).
+
+### Example
+
+```csharp
+public class TestInjectedClass
+{
+    private readonly ILogger<TestInjectedClass> _logger;
+
+    public TestInjectedClass(ILogger<TestInjectedClass> logger)
+    {
+        _logger = logger;
+    }
+
+    public void Hello()
+    {
+        _logger.LogInformation("Hello World from Test Injected Class");
+    }
+}
+
+public class TestPluginServiceCollection : IPluginServiceCollection<SamplePlugin>
+{
+    public void ConfigureServices(IServiceCollection serviceCollection)
+    {
+        serviceCollection.AddScoped<TestInjectedClass>();
+    }
+}
+
+public class SamplePlugin : BasePlugin
+{
+    private readonly TestInjectedClass _testInjectedClass;
+    public SamplePlugin(TestInjectedClass testInjectedClass)
+    {
+        _testInjectedClass = testInjectedClass;
+    }
+
+    public override void Load(bool hotReload)
+    {
+        _testInjectedClass.Hello();
+    }
+}
+```
