Thanks for confirmation. I wondered if there is another way but I suppose not.

I just confirmed what I tend to do, and that has fit every situation that I've needed so far. There may be other ways - What kind of thing were you looking for?

If I knew I wouldn't ask. I thought there is an easier way to do with global settings in Framework 2.0. Ela

I understand I have to create an object of settings class in each project? Ela

I think do not undrestand everything. I have many projects in solution and in almost all of them I need see global varialbes. Do I have to add a references to my "global" class with settings and create an object. There is something wrong. Ela

Colin, Could you provide me with any example for such a specific project? I have one class e.g. public class MyAppSettings : ApplicationSettingsBase { [UserScopedSetting()] [DefaultSettingValueAttribute("true")] [global::System.Configuration.ApplicationScopedSettingAttribute()] public bool someProperty { get { return (bool)this["someProperty"]; } set { this["someProperty"] = value; } } Then I have to create a project dealing with the setting. I suppose it should contain class with static properties?? Could you give me an example? Thanks Ela

...but where to create the object of settings class?

You can create one object only. (The class exists in a single project and it can use the singleton pattern so that only one instance of the object exists across the whole application)

Every time you use your settings class you will need to include the namespace and reference the project that the in which the settings class resides. i.e. In the project that you wish to use the settings class you "Add Reference..." to the project that contains the settings class.

You can use a static class. Although I prefer to use the Singleton pattern because I can mock the class for unit testing.

public static MySettingsClass
{
public bool static SomeProperty
{
get
{
return this.someProperty
}
}
}

My settings classes never have setters. They are readonly.

If you are using the singleton pattern then the class itself creates the object. For example:

public Settings
{
// Field containing the only instance of the class
private static Settings onlyInstance;

// Private constructor so that nothing outside this class
// can construct it.
private Settings(){};

// Property getter to return the only ever instance of the class
public static Instance
{
    get
    {
        return this.onlyInstance;
    }
}

// Add your public methods and properties here

}

Colin, When I was waiting for the answer I managed to do that in such a way you explained and it works! I can make a few changes after reading you responses. Many thanks for the explanation! ...very strange this singleton pattern :-) I had problems with saving settings but I created public method in singleton and called settings save method. Redards Ela
