+# SimpleConsoleLogger Class
+
+**Namespace:** [Grynwald.Utilities.Logging](../index.md)
+
+**Assembly:** Grynwald.Utilities.Logging
+
+A simple console logger that implements ILogger
+
+```csharp
+[NullableContext(1)]
+[Nullable(0)]
+public sealed class SimpleConsoleLogger : ILogger
+```
+
+**Inheritance:** object → SimpleConsoleLogger
+
+**Attributes:** NullableContextAttribute,NullableAttribute
+
+**Implements:** ILogger
+
+## Remarks
+
+SimpleConsoleLogger is a implementation of ILogger that writes log messages to the console.             The behavior of the logger can be customized using [SimpleConsoleLoggerOptions](../SimpleConsoleLoggerOptions/index.md).
