Davyd McColl commented on LOG4NET-611:
--------------------------------------
[~nazgul] I've tried to repro as per your guidance, but to no avail - see:
[https://github.com/apache/logging-log4net/tree/master/src/integration-testing/log4net-611-main]
(net462 and net6.0) which references
[https://github.com/apache/logging-log4net/tree/master/src/integration-testing/log4net-611-lib]
(netstandard2.0, implementing a derived RollingFileAppender).
If you build & run the main .exe, you'll see no errors and the output is
recorded to file & read back out again, eg:
{{> .\log4net-611-main.exe}}
{{Clearing out old logs...}}

{{[console] test log 1}}

{{[console] test log 5}}
{{[console] test log 6}}
{{[console] test log 7}}
{{[console] test log 8}}
{{[console] test log 9}}
{{log file: Logs\2022-07-22-Xyz.xml}}
{{[file] DerivedAppender test log 0}}
{{[file] DerivedAppender test log 1}}
{{[file] DerivedAppender test log 2}}
{{[file] DerivedAppender test log 3}}
{{[file] DerivedAppender test log 4}}
{{[file] DerivedAppender test log 5}}
{{[file] DerivedAppender test log 6}}
{{[file] DerivedAppender test log 7}}
{{[file] DerivedAppender test log 8}}
{{[file] DerivedAppender test log 9}}
Please have a look so I can figure out what's different between my attempt to
repro and your project(s).
