After seeking the web for a good ORM mechanism in regards of developing scalable and generic DAL + BL tier (or service), I bumped into a great article that tested the EF (Entity Framework) hosted in WCF service (SOA architecture).

You can read it here. A short summary of this post says that the EF is still premature and couldn’t perform complex actions (like updating multiple tables that doing some transactions).

Performance and Scalability are also has been tested and the results weren’t so good!

So, after getting some advices from friends and colleges I think I’ll use NHibernate in order to publish my ORM relations to the DB.

Any suggestions or comments to this will be complimented to my email.

I was struggling the basic out-of-the-box datagrid control of Silverlight and it doesn’t do much…

After reading the silverlightshow.net site for some tutorials I revealed the amazing agDataGrid of DevExpress that makes life easier.

Hi,

as I posted in my previous email in regards Silverlight 2, I’ve decided to use ADO.NET Data Services (After consulting my mate Josh Reuben – senior SELA consultant) in order to consume the data in a very easy and light way (by using its linq notation and light weight data bandwidth using JSON).

The only main issue that I encountered with the last few days I am exploring this (new for me) technologies is the issue of cross-domain preventing:

“ADO.NET Data Services does not currently support cross-domain communications. Cross-domain communications are supported with standard REST and SOAP services, but not with ADO.NET Data Services. …… This means that a Silverlight 2 client cannot talk to services exposed through ADO.NET Data Services if those services are hosted on a different domain than the domain that hosts the Silverlight client application.”

Quoted from John Papa post here.

Recently I followed up the the Astoria blog team and found that they created a great workaround that comes to give a solution for this issue that holt me these days using these data services because my application is distributed and need to be separated for a client and server.

I am new to Silverlight 2 and starting these days to develop my first Silverlight application hosted on asp.net web application, which is going to be a large and complex management system for a new product of the company I am working for.

I going to use some new technologies from Microsoft house (like Silverlight, ADO.NET Data Services over WCF and Entity Framework), therefore I started to read some tutorials in regards these topics and must say that there are good tutorials on the web but I read a nice and long post: “Understanding WCF Services in Silverlight 2” that explains how to create WCF Service and more and more (which is quite basic for those that has some knowledge in WCF), but the good paragraph is the detailed info in regards the consuming this service in a Silverlight 2 application.

Check it out here.

Hi,

Long time since my last post I know, but promise to start writing again soon; I am starting these days to write my first big Silverlight 2 application, so I think I’ll have plenty of stuff to share.

For now, great and convenient search engine from google to search MSDN contents (thanks to Erez Eden, my friend that keeps me on track with such nice things…)

You can check it out in the further and save it in your favorites: http://www.google.com/microsoft

Be in touch, promise, Eran.
