+# HTTP logging middleware requires AddHttpLogging()
+
+ASP.NET Core HTTP logging middleware has been updated with extra functionality. The middleware now requires services registered with <xref:Microsoft.Extensions.DependencyInjection.HttpLoggingServicesExtensions.AddHttpLogging%2A>.
+
+## Version introduced
+
+ASP.NET Core 8.0
+
+## Previous behavior
+
+Previously, you could call just `app.UseHttpLogging();` to activate HTTP logging.
+
+## New behavior
+
+Starting in .NET 8, if you don't also call <xref:Microsoft.Extensions.DependencyInjection.HttpLoggingServicesExtensions.AddHttpLogging%2A>, an error is raised:
+
+> System.InvalidOperationException: Unable to resolve service for type 'Microsoft.Extensions.ObjectPool.ObjectPool`1[Microsoft.AspNetCore.HttpLogging.HttpLoggingInterceptorContext]' while attempting to activate 'Microsoft.AspNetCore.HttpLogging.HttpLoggingMiddleware'.
+
+## Type of breaking change
+
+This change is a [behavioral change](../../categories.md#behavioral-change).
+
+## Reason for change
+
+Additional features were added to the HttpLogging middleware that are registered (and configurable) via the <xref:Microsoft.AspNetCore.Telemetry.HttpLoggingServiceExtensions.AddHttpLogging*> method.
+
+## Recommended action
+
+Call `services.AddHttpLogging()` during host construction.
+
+## Affected APIs
+
+None.
