Read Properties.Settings.Default from a different project

Question

In my WPF MVVM application, I have Model, View, and ViewModel as a separate projects. Now, in my View application I have user settings defined in Settings.settings file, I can access them through:

Properties.Settings.Default.MySettingName

and in my Tool.exe.xml I can confirm that the setting is there:

<userSettings>
    <Tool.Properties.Settings>
        <setting name="MySettingName" serializeAs="String">
            <value>False</value>
        </setting>
    </Tool.Properties.Settings>
</userSettings>

Now the question is how do I access those settings from my ViewModel project? It's obvious that if I were to do Properties.Settings.Default.* it will point to it's own settings.

So far I tried to do the following two ways:

Configuration configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
KeyValueConfigurationCollection settings = configFile.AppSettings.Settings;

and

var keys = ConfigurationManager.AppSettings.AllKeys;

But both of them always return 0 entities.

I also know that I can create a ViewModel and bind settings from the View, but for this particular case, creating a new ViewModel just to access setings sounds a little bit overkill.

Thanks for help!

If you are using visual studio you can change the access modifier for the settings class to public. Double click the Settings.settings file and there is a drop down at the top. You can then access the settings using the full namespace — user2697817, Apr 21 '15 at 13:28
A better way would be to provide a service that wraps the settings using `SettingsBase` — user2697817, Apr 21 '15 at 13:31

Thanks to the https://stackoverflow.com/a/632161/1729349

Here's how I was able to access the value of the setting:

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

// find section
ClientSettingsSection configSection = config.SectionGroups[@"userSettings"].Sections["Tool.Properties.Settings"] as ClientSettingsSection;

var setting = configSection.Settings.Get("MySettingName").Value.ValueXml.InnerText;

looked good, but i still only get the default values instead of the values from the config file :-( – Philipp Michalski Nov 04 '19 at 11:58
NVM .. i am just stupid. Visual studio overwrites the config file everytime on build if building another linked project. – Philipp Michalski Nov 04 '19 at 12:34

AppSettings is for the 'default' appSettings configuration section. You need to open your own configuration section. Try this:

ConfigurationManager.GetSection("userSettings");
