StronglyTypedDictionaryGenerator

Roslyn powered source generator for strongly typed dictionaries.

Easily turn an interface into a strongly typed dictionary. Use it for persisting data, interop, serialization, config files, etc.

Generated source

Sample user defined input:
interface IMyInterface
{
    [System.ComponentModel.DefaultValue(69)]
    int Property1 { get; set; }

    bool Property2 { get; set; }

    [System.ComponentModel.DefaultValue(true)]
    bool Property3 { get; set; }

    [System.ComponentModel.DefaultValue("Hello Roslyn!")]
    string Property4 { get; set; }

    CultureInfo Property5 { get; set; }
    
    [System.ComponentModel.DefaultValue(null)]
    TimeSpan Property6 { get; set; }
}

[StronglyTypedDictionary(targetType: typeof(IMyInterface), supportsDefaultValues: true)]
internal partial class MyStronglyTypedDictionary : IMyInterface
{
    private bool someCondition;

    protected override T GetOrDefault<T>(T defaultValue, [CallerMemberName] string name = null!)
    {
        switch (name)
        {
            case nameof(IMyInterface.Property3) when someCondition:
                defaultValue = (T)(object)false;
                break;
            default:
                break;
        }

        return base.GetOrDefault(defaultValue, name);
    }

    public CultureInfo Property5
    {
