C# Fody extension to generate RaisePropertyChange notifications for properties and ObservableAsPropertyHelper properties.
Nuget package ReactiveUI.Fody:
Install-Package ReactiveUI.Fody
Currently, you need to manually add <ReactiveUI /> to your Fody weavers configuration. If this is your first Fody plugin then FodyWeavers.xml should look like this after the change:
<?xml version="1.0" encoding="utf-8" ?>
<Weavers>
<ReactiveUI />
</Weavers>
##Reactive Properties##
Eases the need for boilerplate in your view models when using reactiveui. Typically, in your view models you must declare properties like this:
string _SearchId;
public string SearchId
{
get { return _SearchId; }
set { this.RaiseAndSetIfChanged(ref _SearchId, value); }
}
This is tedious since all you'd like to do is declare properties as normal:
[Reactive]public string SearchId { get; set; }
If a property is annotated with the [Reactive] attribute, the plugin will weave the boilerplate into your
output based on the simple auto-property declaration you provide.
##ObservableAsPropertyHelper Properties
Similarly, in order to handle observable property helper properties, you must declare them like this:
ObservableAsPropertyHelper<string> _PersonInfo;
public string PersonInfo
{
get { return _PersonInfo.Value; }
}
Then elsewhere you'd set it up via:
...
.ToProperty(this, x => x.PersonInfo, out _PersonInfo);
This plugin will instead allow you to declare the property like:
public extern string PersonInfo { [ObservableAsProperty]get; }
It will generate the field and implement the property for you. Because there is no field for you to pass to
.ToProperty, you should use the .ToPropertyEx extension method provided by this library:
...
.ToPropertyEx(this, x => x.PersonInfo);
This extension will assign the auto-generated field for you rather than relying on the out parameter.
