Fonderie source generators

This repository is the home of Fonderie set of Roslyn generators.

These generators need at least Visual Studio 16.8 Preview 2.1 or .NET 5 Preview 8 to work properly.

Fonderie.INPC

This is repository for the INotifyPropertyChanged generator based on field discovery, using C# 9.0 source generators.

Find out more about it in this article.

How to use it

Add the following attribute in your source:

namespace Fonderie
{
    public class GeneratedPropertyAttribute : Attribute { }
}

Add a reference to Fonderie.INPC.Generator, the add the following class :

    public partial class MyClass
    {
        [GeneratedProperty]
        private string _stringProperty;

        [GeneratedProperty]
        private int _intProperty;

        private bool _otherField;

        partial void OnIntPropertyChanged(int previous, int value)
            => Console.WriteLine($"OnIntPropertyChanged({previous},{value})");

        partial void OnStringPropertyChanged(string previous, string value) 
            => Console.WriteLine($"OnIntPropertyChanged({previous},{value})");
    }

The INotifyPropertyChanged interface is automatically implemented, and XXPropertyChanged methods are generated to be notified inside the class if a property changed.

Fonderie.Resw.Generator

This generator is a sample to demonstrate the ability for Roslyn generators to use MSBuild properties and items.
