I disabled the lazy loading in context but now in for some cases I want to use lazy loading in my code but don't want to enable it through the context.
Is there is any way to enable it for the particular block of codes.
Use this http://blogs.msdn.com/b/adonet/archive/2011/01/31/using-dbcontext-in-ef-feature-ctp5-part-6-loading-related-entities.aspx
// I use princesses because ponies are too mainstream
var princesses2 = context.Princesses
.Include("Unicorns")
.ToList();
You simply include the relationship

Checked a number of places, but can't find a coherent concise definition of materialize in the sense of a "materialized system.double type" -- what is the word materialized signifying?
It's a fancy way of saying "deserialized". Read this MSDN page about EF which doesn't actually give a definition but it uses the word enough to clarify things through it's context such as...
Query results are materialized into objects that the Entity Framework manages.

Now I experiment with your application architecture. I have wpf library(AppView.dll MVVM) with my pages (View/MyPage.xaml). I use this library in my wpf app. How do I set the correct URI for navigation ? I tried URI so "pack://application:,,,/AppView;View/MyPage.xaml". But there is an error - "resource not found appview;view/MyPage.xaml". How to use the navigation page from another assembly?
Try using /AppView;component/View/MyPage.xaml or "pack://application:,,,/AppView;component/View/MyPage.xaml"

hi every body
while reading about about coding with c# and asp.net i notice that
files which are (Settings.settings) and the other is
(Settings.Designer.cs) which in one of project layers what kind of
files are they and why he use them ??
Those are application settings, that can be easily edited as a cleartext, human-readable file, and which can be accessed during design-time (and runtime) as classes and properties.

Im busy creating some charts to go on my silverlight application and would just like to know what the .Series[0] represents in the following piece of code
PieSeries pieSeries = ((PieSeries)chart.Series[0]);
Did you check the documentation for the control you're using? What exactly are you having trouble with?
Sec, .Series[0] means to access the Series property, which is an array or list type or indexer, where you want to access the first (zero-based) element (0).

When an event is fired from an element on one tab, how can I have the handler switch the view to a different tab.
I am looking for how to do it in C# code, not xaml. I have done research and cannot find a c# solution.
TabControl.SelectedIndex = <Integer index of the tab you want to display in the 0-based Tab array>
