Hey Dan,

after 12 months trying to master Silverlight, XAML, MvvM and Ria services. now that i get it now, I see your video and I said:

if I had only seen Dan explanation 12 months ago, many frustrations would have been eliminated.

Thank you Dan,

some people are born to develop and some other are born to teach.

you have both

Microsoft should have you explain SL5 and MvvM.. then everybody will get it really fast

Great video, very inspiring, especially around minute 8 regarding the Business Model of the 75%

Thank you Deppesh and of course Thanks John Papa for this great tutorial video.

I have the same question as Aaron on how to use to calculate vertical formulas based on the child values

 private void UpdateOrdersCount() { if (fOrdersCount == null) { fOrdersCount = Convert.ToInt32(this.Evaluate(CriteriaOperator.Parse("Orders.Count"))); } } private void UpdateOrdersTotal() { foreach (Order detail in Orders) { fOrdersTotal
 += detail.Total; } } 

Also

what about using Foreign values on formulas,

on the invoice for example

when a new invoice is created is necessary to add the Total Amount to the customer AmountDue

Thanks

Thank you Dinesh

We need more videos like this one; we're already way beyond the saturated beginner's series that continue to pop up everywhere.

This is the first video I've seen that takes in consideration that many of us started heavy learning the VS2010 Stack over a year ago..

Now I know what I was doing wrong
Doing an include across Many relationship tends to give really bad performance as the generated SQL query is really complex.. I was doing it wrong

Dinesh, You saved my day and many days to come by pointing me on the right direction
