Use dependency injection for Properties.Settings.Default?

Question

Should you consider the use of Properties.Settings.Default within a class as a dependency, and therefore inject it?

e.g.:

public class Foo
{
    private _settings;
    private bool _myBool;

    public Foo(Settings settings)
    {
        this._settings = settings;
        this._myBool = this._settings.MyBool;
    }
}

.
.

or would you consider the use of Settings as an application wide global as good practice?

e.g.:

public class Foo
{
    private bool _myBool;

    public Foo()
    {
        this._myBool = Properties.Settings.Default.MyBool;
    }
}

Answer 1

I would choose "none of the above" and inject the boolean value directly:

public class Foo
{
    private readonly bool _myBool;

    public Foo(bool myBool)
    {
        _myBool = myBool;
    }
}

This decouples Foo from knowledge of any infrastructure that supports the retrieval of the boolean value. Foo has no reason to introduce complexity by depending on a settings object, especially if it contains other unrelated values.
