Delete file locked by the enterprise library [SOLVED]

Dear,

I'm using the enterprise library 5.0 in order to register the exception thrown into a log file in a windows WPF application.

ExceptionPolicy.HandleException(exception, "ExceptionPolicy");

And also I have added the functionality in order to delete the file on click.

File.Delete(logFilePath);

Scenario:

1. If the log file is full but no exception has been raised:
   >> The file is deleted smoothly.
   
2. If the log file is full and an exception is raised:
   >> An additional exception is raised informing that the file could not be deleted because it is used by another process.
   

EDIT ================

I have found the solution, all I have to do is:

Add reference to the enterprise Logging DLL:

using Microsoft.Practices.EnterpriseLibrary.Logging;

And then add Logger.Writer.Dispose(); before File.Delete(logFilePath):

[...]
Logger.Writer.Dispose();
File.Delete(logFilePath);
[...].
