I did not like the singleton pattern you used in the Win8 LOB In Depth talk…  It looked something like this:

public class MySingleton()

{

      private MySingleton() {} //Private cstr

      private static MySingleton _instance;

      public static MySingleton Instance {

            get {

                  if (_instance == null)

                        _instance = new MySingleton()

                  return _instance;

            }};

}

This is too much code and it is not thread-safe when multiple threads call MySingleton.Instance at the same time.  You need to add double-check locking to make it thread-safe.

Cleaner option:

public class MySingleton()

{

      private MySingleton() {} //Private cstr

      public static readonly MySingleton Instance = new MySingleton();

}

The class will be constructed the first time MySingleton.Instance is called and will be get-only because of readonly.  This is also thread-safe without any locks (handled  by the CLR).  This is a Poor Man's singleton, because serious applications will have an IoC container to provide singletons.

Thanks for the double session – I picked up a few useful tips.  Hopefully I am telling you something new and useful above in return J

I’ve created a Sample project and updated some problems with the Pie Chart and Attached the App to this Blog post and again sorry for not replying to many of you but I’ve been really really busy “ Windows 8 is Rocking “

The SkyDrive link is Here http://sdrv.ms/W2fv9n

Regarding the codeplex Project you can follow any of the Silverlight Toolkit Samples as it is an Exact Replica use Porting it to Windows 8

So As a Matter of Fact I successfully Migrated the Famous Sliverlight toolkit to be running on Windows 8 Modern UI Applications.

Well, not everything is there yet since I’m Migrating Class By Class while understanding how things are working on this huge components

You can follow my project on CodePlex http://modernuitoolkit.codeplex.com/ 

For Now you can find the Bar , Line , Column Chart and mixed Series Available, And I’m looking for people how can join me on this as it’s a very big project and I believe that this is the most advanced charting controls available for windows 8 So far with your help it can be even better.

You can help with Ideas, Development Testing Bugs Reporting etc,

Sample of my Charts in Action

this error really got me really hard I traced down the problem I found out that the problem is because of a the . in my Assembly name I was Generating from that project “was working great in early release of Visual Studio”

anyway it was declared as error by Microsoft and they are doing to release a Hotfix for it soon. as a Quick correction you can remove the DOT from your assembly name.

Check the below Article on technet for more details.

Basically here is the solution answer for you use the following snippets will solve your problem

https://skydrive.live.com/redir?resid=8B60D1F5DEC2AAA7!332&authkey=!AC1FuVjc6ZUPQKw

- Support Default and Hole Type PieChart

- Legend and Tooltips

- Pushout feature for on Click events

- On Select and DeSelect Item from the PieChart

Feel free to contact me if you need the source code and find below the download link for the assembly file Download Here

when you build a Custom control for Windows 8 by Default InitalizeComponents will not be available so you need to build the method on your own to load controls from it

The Initialize Components Method needs to do the following

1. Load your Xaml file and Attach it to the Solution

2. Load your Controls into your Controls

Below is a Sample of how you can construct the InitalizeComponents Method

as you can See I loaded the xaml file first using Application.LoadComponent

then used the method FindName in usercontrol to load the relative controls to my class, I hope that this post was helpful and thanks
