example project and binaries

Steps to reproduce:

  * Create empty application referencing log4net
  * add log4net section to app.config
  * deploy log4net.dll to a subdirectory and add that directory to the privatePath in the app.config

Expected outcome: log4net is found in configured privatePath in all cases

Actual outcome: probing for log4net causes a System.IO.FileNotFoundException: Could not load file or assembly 'log4net, ...' if the log4net section is before the runtime section in the app.config file.

I've added a example project demoing the effect. running the test exe in the ProbingPathTest/bin/Works directory finds the log4net dll, with the config in the ProbingPathTest/bin/Fails the exception is thrown.

I'm testing on $ mono --version

Comment 1 Ludovic Henry 2018-04-05 20:49:01 UTC

Thank you very much for the reproduction case, I can reproduce with (master/df33c092de3).

Observed behavior:

 - download and unzip https://bugzilla.xamarin.com/attachment.cgi?id=6686
 - $> cd ProbingPathTest/bin/Fails
 - $> mono ProbingPathTest.exe # Fails

Expected behavior:

 - download and unzip https://bugzilla.xamarin.com/attachment.cgi?id=6686
 - $> cd ProbingPathTest/bin/Works
 - $> mono ProbingPathTest.exe # Succeed

The difference between both `Works` and `Fails` is in `ProbingPathTest.exe.config`:
 - in `Fails`: the `<log4net>` XML element is *before* the `<runtime>` XML element
 - in `Works`: the `<log4net>` XML element is *after* the `<runtime>` XML element.
Comment 2 Aleksey Kliger 2018-04-11 15:51:16 UTC
The mono native C XML parser doesn't like this element: "<appender-ref .../>"  The hyphen is a problem.  (It also doesn't like underscores and periods in element names).
