NotifyPropertyChangedGenerator

Roslyn Analyzer/Generator for avoid boring boilerplate INotifyPropertyChanged implementation.

Installation

You can donwload from NuGet, NotifyPropertyChangedGenerator.

PM> Install-Package NotifyPropertyChangedGenerator

Supports platforms are all and all .NET Framework(3.5 supports!) but requires Visual Studio 2015.

What is this?

Super lightweight to write INotifyPropertyChanged
Keeping code clean in view
Being strong in a change
POMO(Plain Old MVVM Object), you don't need inherit base class

Static analyzed. NotifyAttribute to class or NotifyAttribute to property, Roslyn Analyzer checks are all target properties implemented(generated) Notify property. If not, output compiler error.

If set NotifyAttribute to class, target properties are all property. You can ignore set NonNotifyAttribute to nontarget property. If set NotifyAttribute only to property, its target property is opt-in.

Press Ctrl+.(Lightbulb QuickFix), preview the change.

The modified class is clean, noisy boilerplate codes are lower in the code, not around a property.

Configuration

Default naming rule of backing field is plain lowerCase. If you want to change _lowerCase, configure NotifyAttribute.cs's interface for example to LeadingUnserscore is here.

[Conditional("NEVER_USED_AT_RUNTIME")]
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Property, AllowMultiple = false, Inherited = false)]
internal sealed class NotifyAttribute : Attribute,
    // option, you can customize naming convention rule
    NotifyAttribute.ILeadingUnderscore
{
    // naming convention markers
    internal interface IPlain { }
    internal interface ILeadingUnderscore { }
    internal interface ITrailingUnderscore { }

    /// <summary>
    /// No option.
    /// </summary>
    public NotifyAttribute() { }

    /// <summary>
    /// Specify options.
    /// </summary>
    /// <param name="compareMethod">Comppare kind for raise property changed.</param>
    public NotifyAttribute(NotifyCompareMethod compareMethod) { }
}

What is different with Code Snippet?

Code snippet is easy to write but difficult to read. Generated code is very noisy because code snippet does not support that generate to separating.

What is different with PostSharp or Fody?

There are easy to write and easy to read but difficult to build and debug. NotifyPropertyChangedGenerator is only simple compile time analyze/generator and fully Visual Studio integrated.
