#### Types that implement IErrorHandler

Type | Description
--- | ---
OnlyOnceErrorHandler | Implements log4net's default error handling policy which consists of emitting a message for the first error in an appender and ignoring all subsequent errors.

#### Remarks

Error handling is a particularly tedious to get right because by definition errors are hard to predict and to reproduce.

#### Requirements

Namespace: log4net.Core

Assembly: log4net (in log4net.dll)
