Is there any possibility to change the source name of NLog.config dynamically if yes can any one please help me.

<targets>
<target xsi:type="EventLog" name="eventlog" layout="${callsite}:${message}" log="Application" **source="MyAwesomeSolution"**/>

this is the source name which i wanna change with parameters coming from other method to NLog.Config file. source="MyAwesomeSolution"

Thanks in advance.

You can use any predefined variable or your custom field in the source field.

eg source="${event-properties:item=customName}"

and in your code, you can fill this value

logger.Info("this event is coming from may {customName}", "my app");

or you can use

logger.SetProperty("customName", "my app");

or even

logger.WithProperty("customName", "my app").Info("test message");
