Introduction

In Part 5 I discussed metadata classes and shared code, and one of the example uses of metadata classes I showed was using a [Required] validation attribute to cause some validation on both the client and server side.

Introduction

In this article, I am going to quickly cover the metadata and shared code facilities of WCF RIA Services.

Introduction

As you probably know there is no DataGrid available under the Silverlight for Windows Phone platform at the moment. One could object that a DataGrid in Windows Phone is not so much requested for a lot of reasons, size of the screen, user input mode etc. This is true but it is also true that new projects regarding local databases appear day by day on the horizon (i.e. Perst for WP7 , Windows Phone 7 Database) and this opens the space for the development of a class of business applications, even for small devices.

 This article is Part 2 of the series Sketchflow from a developer point of view:

1. SketchFlow from a developer point of view - Part I - Basics 
2. SketchFlow from a developer point of view - Part II - Dev Stuff

More Sketchflow questions, scenarios and advanced Sketchflow issues will be covered by Braulio Diez in his upcoming webinar: Sketchflow in Real Scenarios.

Intro

In the first part of this article we learnt why was so important to add to our lifecycle a quick and dirty prototyping stage, and learnt as well how to perform that basic sketch prototyping using Sketchflow.

So far so good… till now the sensation you can have can be something like: Ok, Sketchflow is just another prototyping tool… in this second part of the series we are going to check what makes Sketchflow an advanced prototyping tool: sketching some static images or canned / styled controls with some basic navigation is not bad but not good enough !! We need to validate with the client animations, gestures, behaviors….

 This is part 5 of the Windows Phone 7 series:

Software Distribution in Windows Phone 7

There will be only one way for distributing our applications and it’s called Market Place. This means that there will be no more cab files or anything else. Market Place is an application, which comes with Windows Phone 7 OS. All the applications for Windows Phone 7 will be available for purchase and download thru Market Place. There will be two methods to pay for an application – with credit card and thru your mobile operator (by adding an application fee to your monthly bill).

Introduction

The Model-View-ViewModel pattern (MVVM) is a very popular approach for building more loosely coupled Silverlight and WPF applications.

1. The Problem

In this article I’ll show you a simple solution for navigation between pages in different Xaps, by using Managed Extensibility Framework (MEF). Recently I hit the following issue, while playing with MEF. Suppose that you have a Silverlight Navigation Application. Your application is partitioned in different modules (plugins, extensions, add-ons or whatever). Let's imagine that 
your application has three plugins – Orders plugin, Products plugin and Suppliers plugin, as shown on the snapshot below.
