Hi All,

Am working on a solution that uses "Ent.Lib 4.0". 

I want logging and exception handling to go to the same file but when an exception is thown a new separate file is created.

How can i make Exception Handler & Logger use the same log writer??

In "Ent.Lib 5.1" I use the following to achieve this...

_traceManager = EnterpriseLibraryContainer.Current.GetInstance<TraceManager>();

Is this possible in 4.1 and if so what is the syntax?

This is the expected behavior when useDefaultLogger is set to false (the default).  From the release notes:

The Logging Handler has a new Boolean property named UseDefaultLogger. When set to True, the handler writes every log event and exception to the same file. When set to False (the default) it writes log event and exception information to separate files named with a GUID.

So change the configuration to set useDefaultLogger to true:

      <add name="Policy">
          <add type="System.Exception, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089"
            postHandlingAction="NotifyRethrow" name="Exception">
              <add logCategory="Error" eventId="100" severity="Error" title="Enterprise Library Exception Handling"
                formatterType="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.TextExceptionFormatter, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
                priority="0" useDefaultLogger="true" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging.LoggingExceptionHandler, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
                name="Logging Handler" />
