Enterprise Library Exception: The configuration section for Logging cannot be found in the configuration source.

[Jess Chadwick]

Hi,

I am getting the following exception when attempting to open a site with
using the Enterprise Library Logging block:
The configuration section for Logging cannot be found in the configuration
source.
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.

Exception Details: System.Configuration.ConfigurationErrorsException: The
configuration section for Logging cannot be found in the configuration
source.

This happens in my test environment that is using the same exact
configuration as my development environment, where it works great... Any
ideas?

Thanks,
Jess

Hello Jess,

From your description, I understand you're receiving an "The onfiguration
section for Logging cannot be found in the configuration source" exception
when try starting an ASP.NET application which use the enterprise library,
correct?

As for the enterprise library component, are you using the entlib 2005(.net
1.1) or entlib 2006(.net 2.0) version? For the 2005 version, it will use
separate configuration file for each application blocks in it while for
2006(.net 2.0) version, the enterprise library has centralized most
settings in the application's configuration file(app.config file or
web.config file for ASP.NET application). If you're using 1.1 version, you
need to check whether the main configuration sections in
app.config(web.config) and those separate configuration files(for each
application block) is correctly copied to the target place(or whether the
content is identical to the orignial one). If you're using 2.0 version,
normally you just need to check the main app.config(web.config) for the
enterprise library specific configuration settings.

As for the host appliation, is it a normal .net desktop(winform or console)
application or ASP.NET web aplication. If it is an ASP.NET web application
and hosted in IIS virtual directory, you also need to take care of the
virtual directory hierarchy of your application. This is because ASP.NET's
configuration section is hierarchyically inherited. Sub virtual directory
will inherit web.config setting super level directory. You can compare the
directory structure between the development server and test server to see
whether there is any difference on this also.

In addition, if convenient, I would suggest you try creating a simplified
project (exclude some non-related code and content) which can reproduct the
same error so that we can concentrate our troubleshooting on tha simplified
one. You can also send such a test project to me so that I can also help
perform some test on my side.

Please feel free to let me know if there is anything we can help.

Sincerely,

Steven Cheng

I'm having the same problem with a C# 2005 Class Library project. I will send a simple test project with unit test as an example.

Hi Steven,

I have the same exception when VS form designer try to load my form.

I have a Windows application with a user control. I put an instance of my

method.

when I run my application every thing is OK.(i prove my App.config is ok).
but when i try to open form1 in design time, I get the following exception
and designer is not able to show my form!!!
