CSLA .NET 3.5 preview release

With luck “Expert 2008 Business Objects” will be out around July.

Thats great news Rocky! I'm looking forward to using Csla.net 3.5 in an upcoming LOB project. I've been using Csla.net 2.0 until now with great success. When can we expect a "hard copy" book release similar to the one for Csla.net 2.0 that starts from the bottom up? Keep up the good work. 

There are two LINQ related features for 3.5.

The first is indexed queries, which have been discussed in another thread. They are largely complete in C# and are being ported to VB. This is a useful feature if you do repeated equality searches against a list (BLB or ROLB).

The second addresses one of the most likely negative scenarios with LINQ. If you do this:

var data = from i in someList select i;

What you get back is an IEnumerable<ItemType>. The items themselves still belong to the original list object, but you can manipulate them through the query result. If you add or remove items from “data” it has NO IMPACT on the actual list. That is potentially quite confusing, especially if you bind “data” to a grid and expect the user to get useful results as they interact with the data in the grid.

So the second feature will ensure “data” is something more complex – a LinqBindingList<T>. This is still a list containing the query result, but it is like FilteredBindingList or SortedBindingList, in that it is a live view of the original list. So when items are added/removed from “data” in this case, they are also added/removed from the original list. The result is much more what you’d normally expect, especially if you bind the UI to this result.

First of all great work...
but i must say you have wet my apatite with "though the C# version doesn't have the coolest parts yet either"... may i ask what plans you have in store.
Thanks

I am still shooting for a Jan 25 beta release. Depending on how the beta goes, and how much time I have free given that I’m spending 3 weeks traveling to a client in February, I’d like to think a release at the end of February is possible. Or mid-March maybe.

Great News Rocky!  I have to say your framework has saved a ton of time developing as well as creating stardard modules and methodologies for all of us to work off of.  Keep up the great work.

We have a list of upgrades to perform this spring (Infragistics, DevExpress, and of course CSLA)... we would like to plan it around the 3.5 Production Release... do you have a timeframe for that release?

Thanks,

I’m going as fast as I can to get the new features themselves done and tested. That requires updating ProjectTracker to make sure it all works in the (rapidly increasing) combination of scenarios of UI and data portal. Things like the snippets will come next, and to be honest, the templates may not get updated until I get to Chapter 7 in the book (that’s where they are on my critical path).

Unfortunately my wife’s grandfather just passed away earlier today, and that will likely mean a delay in the beta release from Jan 25 to sometime later. I don’t yet know enough details to predict the impact, but I’m sure everyone understands that family comes first.

Rocky,

I downloaded the 3.5 preview and noticed the code snippets and templates have not been updated.  Do you know when the new versions will be available?  Thanks.
