public class MyInt
{
    int value;
    Subject<int> changed = new Subject<int>();
    public int Value
    {
        get { return value; }
        set
        {
            if (value == this.value)
                return;
            this.value = value;
            changed.OnNext(this.value);
        }
    }

    public IObservable<int> Changed
    {
        get
        {
            return changed.AsObservable();
        }
    }

    public static void Test()
    {
        var a = new MyInt();
        var b = new MyInt();
        var c = new MyInt();

        // Setup Sum function that is called after any change to args.
        Observable.Merge(a.Changed, b.Changed, c.Changed)
            .Subscribe(i =>
                {
                    int result = a.Value + b.Value + c.Value;
                    Console.WriteLine("Update Sum: " + result);
                });

        // Program can now set Values anywhere and Sum will be updated.
        a.Value = 1;
        b.Value = 1;
        c.Value = 1;
        c.Value = 5;
    }

Everyone who builds the multi-layered bussines applications which goes a little beyond the simple master-details forms, arrives at a framework which has to take care of these things.

That's not something for everyone. I came under the impression that the people building visual studio & tools had no real world experience with this stuff. I always wondered what the dynamics/navision people thought about that.

And here you are.

After building my own orm/frameworks/viewmanagers/service layers and what not, I alway wanted to make it complete with some designers/wizards & tools to make building the app itself and bussiness rules a little bit easier.

That's what lightswitch really is. And off course there will be trade offs, and it's a 1.0 (still beta) version.

But it looks very very promising ! And not only for the ex-foxpro/ms access/clipper developers!

And with the azure/cloud route, it has to be a sure winner.

Any targets known about rtm/rtw ?
