I googled this a little but couldn't find a good result.
Right now I'm building a web site and I'm trying to make it as correct as possible from a design point of view from the beginning.
The problem I'm now facing is that when deciding to start with logging I needed a project to place this code in. As I could not find a suitable place in my currect projects I thought: hey, why not a logging class library?
Is there a general guideline on how many projects you should have? I know this would be a rather small project but it would be nice to entirely get it out of my way!
Any hints are appreciated :)
Absolutely you should have a logging library. And if you're going to make this as 'correct as possible from a design point of view' and your proect is less than trivial then you should definitely have some number of projects. The thing is, we have no idea what you're working on besides the fact that it's a web app. It's the biz domain that often determines how complex your solution has to be.
