# Interface ILogger

Base interface for SDK loggers.

## Namespace: StylelabsStylelabs.MSdkStylelabs.M.Sdk.ContractsLogging

## Assembly: Stylelabs.M.Sdk.dll

## Syntax

```csharp
public interface ILogger
```

## Remarks

Performance tips:

- For static or constant strings, construct and pass the string directly.
- For dynamic strings that require IO, make sure to pass a to the logger.
- It is recommended to always pass a for debugging messages. This way, when debugging is disabled, the debug calls will have virtually no overhead. If you construct and pass strings directly, it will always have more overhead.
