There are a number of ways of dealing with this issue.
* Using separate source files when completely independent
implementations are required.
Consider for example the Windows.Forms, we will probably
have completely different versions of it depending on the
platform we will run.
* Using defines.
Defines look ugly and make your code look ugly, so this
should be used with care, and only in a few justified
Pretty much any piece of code like this:
That is just plain ugly and it grows to be horrible.
It can be changed into having an `architecture' depending
bit and a generic bit. So you can turn that code always
And then you have different implementations of Blah, see the
* Using auxiliary system classes.
Things like path separators could be abstracted in a class
called System.Private.Parameters, and then classes that need
to use that information would retrieve that from it.
