Do not write exceptions to console

[RalfKoban]

Sometimes, especially with ReSharper, developers write code that catches an exception and writes the exception to the console.

Example:

try
{
    // do something
}
catch (Exception e)
{
    Console.WriteLine(e);
    throw;
}

We should report if the exception is written to the console.

Reason:
This could be a security breach (detailed information about the system, like the application’s path or file names could be leaked here).
