Question

I have a sln, where a consile application is the starter of thr solution.

How is it possible to log from library project to the console?

(I mean the dll project propapbly don’t allow that,

as it is not always run by the console application. Sometimes by other framework, no?)

Answer 1

It is technically possible for any code to use the System.Console class to write to the console. However, it is not good form for a library to do this for a number of reasons, including:

• writing to the console is relatively expensive because a process-wide lock is required for synchronization purposes
• writing to the console from a library will likely annoy anyone consuming that library from a console application. It would likely make the library such a hindrance that it would not be used in such a context

Instead, you would usually use a logging abstraction such as that provided by System.Diagnostics.TraceSwitch or by a logging library like log4net. Then you can configure the application to redirect logging statements to the console, another file, a database, or whatever you like really.
