EntLib Config Tool - Admin rights required for Custom Trace Listener

Topics: Logging Application Block
Dec 17, 2012 at 12:04 PM

I was experimenting with creating a Custom Trace Listener and I finally got the Design Time features to work so that I can edit the properties of my custom listener in the EntLib Configuration Tool. I was doing this experimentation at home on my personal computer where I have admin rights on the machine.

I was thinking about implementing a similar Custom Trace Listener in my Enterprise Environment but we do not have local admin rights in our environment. I was wondering if there is any other way to get the design time features to work without having to put my .dll in the "C:\Program Files (x86)\Microsoft Enterprise Library 5.0\Bin" directory.

For application development my preferred method is to use the EnterpriseLibrary.Config extension.  This integrates into Visual Studio and lets you specify an arbitrary Enterprise Library binaries path (on a solution level) which let's you set multiple search paths to look for Enterprise Library assemblies E.g. if you are using Nuget you might see something like this: 


This let's you append any path you want to pick up custom assemblies or even custom Enterprise Library builds.

Another alternative would be to install/deploy Enterprise Library into a non-admin location.

Maybe I am missing something but I believe EnterpriseLibrary.Config is exactly what I am using (see screenshots below).

1) The "Logging" project holds my custom trace listener and associated configuration class so that I have design-time support using the EnterpriseLibrary.Config tool. The "SysloggerTest" project is a Console Program that I have configured to use my custom trace listener for logging. (This was configured using EntLibConfig.exe on a machine outside of my corporate environment in which I was able to write to the "C:\Program Files (x86)\Microsoft Enterprise Library 5.0\Bin" directoy).


2) This is the error I get when I try to open the app.config under the "SysloggerTest" project with EntLibConfig.exe.


To summarize: I am able to use my custom trace listener within my application no problem and the logging works. My issue is that the EnterpriseLibrary.Config tool itself wont have design time support unless I can copy my custom .dll into the \Bin directory of the EntLibConfig.exe install.

Edit 1: I was mistaken - I am not able to run the program either

Edit 2: Cool - It looks like the EnterpriseLibrary.Configuration extension is what I need

Ok - I guess I was wrong. I set the "Enterprise Library binaries paths" to:

GlobalSection(ExtensibilityGlobals) = postSolution
     EnterpriseLibraryConfigurationToolBinariesPath = C:\Users\xxxxxxx\Desktop\SysloggerTest\Logging\bin

and it still doesnt work. Same error as screenshot 2 above,

It should work as long as you have all the assemblies in the C:\Users\xxxxxxx\Desktop\SysloggerTest\Logging\bin directory and that the configuration has the correct type information.  So the C:\Users\xxxxxxx\Desktop\SysloggerTest\Logging\bin should have the following assemblies:


You can also take a look at the Sample Trace Listener project: Samples.TraceListeners.zip which is configured to use the configuration tool with the binaries path.
