#### Thread Safety

This type is not safe for multithreaded operations.

#### Remarks

This attribute may only be used at the assembly scope and can only be used once per assembly.

Use this attribute to configure the XmlConfigurator without calling one of the Configure methods.

If neither of the ConfigFile or ConfigFileExtension properties are set the configuration is loaded from the application's .config file. If set the ConfigFile property takes priority over the ConfigFileExtension property. The ConfigFile property specifies a path to a file to load the config from. The path is relative to the application's base directory; BaseDirectory. The ConfigFileExtension property is used as a postfix to the assembly file name. The config file must be located in the application's base directory; BaseDirectory. For example in a console application setting the ConfigFileExtension to `config` has the same effect as not specifying the ConfigFile or ConfigFileExtension properties.

The Watch property can be set to cause the XmlConfigurator to watch the configuration file for changes.

> Note

> Log4net will only look for assembly level configuration attributes once. When using the log4net assembly level attributes to control the configuration of log4net you must ensure that the first call to any of the LoggerManager methods is made from the assembly with the configuration attributes.

> If you cannot guarantee the order in which log4net calls will be made from different assemblies you must use programmatic configuration instead, i.e. call the Configure method directly.

#### Requirements

Namespace: log4net.Config
