Using Silverlight 2.0 clientaccesspolicy.xml vs. crossdomain.xml for Web-Service cross-domain access

September 29th, 2008
To enable a Silverlight control to access a web service (like a WCF Service) in another domain, the service must explicitly allow cross-domain access.

September 28th, 2008
Cool!, just a few days ago (Thu Sep 25 2008) Microsoft P&P have published a neat 'Application Architecture Guide' (v.2.0). It is great because "it is new", so it covers most of the new Microsoft dev technologies and application/architecture types we're dealing with, nowadays. :-) Even though P&P have published just "the begining", in ...

Updating data using Entity Framework in N-Tier and N-Layer Applications (short lived EF contexts) – (Part 1)

September 4th, 2008
First of all, we are talking about using Entity Framework and how it fits within N-Tier and N-Layer applications, ok?, that’s our initial scenario. An N-Tier application is an application where you have 3 or more physical tiers. I mean with that things like, “Presentation/Client Tier”, “Application/Business Server Tier” and “Data ...

August 21st, 2008
The Zachman Framework is a grid of artefacts used to describe an enterprise architecture. Zachman does not require the whole grid filled. Nor is it necessary for only one artefact to correspond to each hook. It is therefore a fairly messy key holder. Nevertheless it is pretty handy. It prompts the architects to think about what is needed in a ...

July 25th, 2008
The concept of ISB is quite similar to the ESB but putting it in the cloud, Internet, so is it a way to connect/consume different "enterprise apps" thru Internet and therefore thru firewalls. But starting from the begining..., with platform technologies including Windows Server, the .NET Framework, BizTalk Server, and other ...
