PhoneWave

This is a transaction-based changes tracker for your models.

How to use

For simplest case of tracking property values, see the example project.

TL;DR:

Declaring your model classes:

[TrackProperty(typeof(MyType), "MyTypePropertyName")]
public partial class MyModel : PhoneWaveBase
{ 
    public MyModel(PhoneWaveContext context) : base(context) {}
}

Making changes to your model:

using (var tran = myModel.Context.BeginTransaction("Changed MyTypePropertyName"))
{
    myModel.MyTypePropertyName = myNewValue;
    tran.Commit();
}

Actually undoing/redoing stuff:

if (myModel.Context.CanRollback)
    myModel.Context.Rollback();
    
if (myModel.Context.CanRollForward)
    myModel.Context.RollForward();

Whenever you're doing something wrong, you're getting an exception.

Also check out dictionary and collection tracking classes, you might find these useful too. You will need read-only properties for these, constructed under the parent object's PhoneWaveContext.
