Change name of source in Enterprise Library Logging - visual-studio-2013

Question

I am using Enterprise Library Logging to easly log to my Event Viewer in windows.
But I don't know how to change the source if possible in Enterprise Library logging to the name of my application (MyApp for example).
I am using a visual editor to easly edit the options in Enterprise Library Logging called: Enterprise Library Configuration as you can see in the picture.
This is my App.config file that is generated by the Enterprise Library Configuration Editor:
<configuration>

Answer 1

The anwser is that you need to run the console as administrator once so that it can create the source.
I am using this visual studio 2013 plugin for editing the config on an easy way.

Answer 2

Just going to add, if you want to do this programmatically (instead of in the app.config), the place to change it is in the properties of the EventLog object, as so:
// Trace Listeners
var eventLog = new EventLog("Application",
".",
"MyApp Event Logging");
var eventLogTraceListener = new FormattedEventLogTraceListener(eventLog);
And then build the rest of your LoggingConfiguration as you otherwise would.
