Define "user settings"? M.E.C doesnt support two-way config updates very well, so it might not be ideal for that usecase.

basically settings that the end-users can change

Pobiega•13mo ago

by editing the config file manually, or through some WPF interface in your app?

ricecracker2234•13mo ago

through the wpf interface with bindings

Pobiega•13mo ago

Right. Thats unfortunately not the best usecase for M.E.C afaik

it has good support for reloading the file as it changes, but it doesnt have two-way binding support

ricecracker2234•13mo ago

so what's a good library for handling user settings in general?

Pobiega•13mo ago

Whats wrong with System.Configuration? it supports two-way binding

ricecracker2234•13mo ago

does it support other types like enums?

I have no idea. Lets try. can confirm, works fine with enums strings, ints are all fine too it gets xml serialized by default

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <section name="TestSettings" type="WpfApp1.TestSettings, WpfApp1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
    </configSections>
    <TestSettings OptIn="HellYes" />
</configuration>

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <section name="TestSettings" type="WpfApp1.TestSettings, WpfApp1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
    </configSections>
    <TestSettings OptIn="HellYes" />
</configuration>

public class TestSettings : ConfigurationSection
{
    public const string SectionName = nameof(TestSettings);

    [ConfigurationProperty(nameof(OptIn), DefaultValue = CoolEnum.Unknown)]
    public CoolEnum OptIn
    {
        get => (CoolEnum)this[nameof(OptIn)];
        set => this[nameof(OptIn)] = value;
    }
}

public enum CoolEnum
{
    Unknown,
    HellYes,
    PleaseNo
}

public class TestSettings : ConfigurationSection
{
    public const string SectionName = nameof(TestSettings);

    [ConfigurationProperty(nameof(OptIn), DefaultValue = CoolEnum.Unknown)]
    public CoolEnum OptIn
    {
        get => (CoolEnum)this[nameof(OptIn)];
        set => this[nameof(OptIn)] = value;
    }
}

public enum CoolEnum
{
    Unknown,
    HellYes,
    PleaseNo
}

I made a shitty window that has a TestSettings instance (added and fetched from the Configuration object made by ConfigurationManager.OpenExeConfiguration) set as its datacontext and bound it there. Works fine setting values, changing values, restarting the program etc.

Thats fair. Set up a simple POCO object for your config, add some Load/Save methods and you're done thats probably a lot easier 😄
