        This rule raises an issue on logging calls inside a catch clause that does not pass the raised Exception.

        Why is this an issue?

        How can I fix it?

        More Info

        A log entry should contain all the relevant information about the current execution context. The Exception raised in a catch block not only provides the message but also:

        • the exception type
        • the stack trace
        • any inner exceptions
        • and more about the cause of the error.

        Logging methods provide overloads that accept an Exception as a parameter and logging providers persist the Exception in a structured way to facilitate the tracking of system failures. Therefore Exceptions should be passed to the logger.

        The rule covers the following logging frameworks:

        • Nuget package - Castle.Core
        • Nuget package - Common.Core
        • Nuget package - log4net
        • Nuget package - NLog
        • Nuget package - Microsoft.Extensions.Logging
