== Why is this an issue?

A log entry should contain all the relevant information about the current execution context. The https://learn.microsoft.com/en-us/dotnet/api/system.exception[Exception] raised in a catch block not only provides the message but also:

* the exception type
* the https://learn.microsoft.com/en-us/dotnet/api/system.exception.stacktrace[stack trace]
* any https://learn.microsoft.com/en-us/dotnet/api/system.exception.innerexception[inner exceptions]
* and more about the cause of the error.

https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.logging.loggerextensions[Logging methods] provide overloads that accept an `Exception` as a parameter and 
https://learn.microsoft.com/en-us/dotnet/core/extensions/logging-providers[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 - https://www.nuget.org/packages/Castle.Core[Castle.Core]
* Nuget package - https://www.nuget.org/packages/Common.Logging.Core[Common.Core]
* Nuget package - https://www.nuget.org/packages/log4net[log4net]
* Nuget package - https://www.nuget.org/packages/NLog[NLog]
* Nuget package - https://www.nuget.org/packages/Microsoft.Extensions.Logging[Microsoft.Extensions.Logging]
