Debugging a WCF Service
Following are the 3-different ways to start debugging a WCF service:
· When you are debugging a client process that calls a service. Here debugger steps into the service also service does not have to be in the same solution as your client application.
· When you are debugging a client process that requests to a service and here service must be a part of your solution.
· When you are using Attach to Process to attach to currently running service. Here debugging begins inside the service.
Debugging with Visual Studio 2008
Using Visual Studio 2008, one can step into a WCF service. One can hit break points inside the WCF service, if the WCF service is in the same solution as the client.
For stepping to work, you must have debugging enabled in the app.config or Web.config file we will discuss later on the limitation and how to enable debugging.
To step into a WCF Service
Limitations of Debugging a WCF Service
1. Stepping Into a Service
The following conditions should be met when you start To step into a service from a client applications:
· Service must be called bys using a synchronous client object.
· One-way contract operation is not allowed.
2. Stepping Out of a Service
The limitations are the same as described the above, in addition, here the debugger must be attached to the client.
This is because while you are debugging a client and step into a service, the debugger remains attached to the service whether you started the client by using Start Debugging or attached to the client by using Attach to Process.
But while you are debugging by attaching to the service, the debugger is not yet attached to the client. In that case, you must first use Attach to Process to attach to the client manually.
Debugging must be enabled
3. Automatic Attach to a Service
Automatically attaching to a service has the following limitations:
· In this case the service must be part of the solution you are debugging.
· The service must be hosted. Which means it may be part of a Web Site Project (File System and HTTP), Web Application Project (File System and HTTP), or WCF Service Library project. WCF Service Library projects can be either Service Libraries or Workflow Service Libraries.
· WCF client must be invoked the service.
· Debugging must be enabled
Enabling Debugging a WCF Service
Use following piece of lines in web.config or asp.config file(s):
<system.web>
<compilation debug="true" />
<system.web>
Note: In case when you use Attach to Process on a service, the debug code is automatically added to the .config file.
How to Debug a Self-Hosted WCF Service?
In simple words WCF service which does not run inside IIS, WCF service Host or ASP.NET Development Server is know as Self-Hosted Service.
To debug such services we need to configure Visual Studio to launch both client and server when you choose Start Debugging on the Debug menu.
1. Need to create a Visual Studio solution pertaining both the client and server projects.
2. Now configure the solution to start both client and server :
a. From Solution Explorer, right-click the solution name.
b. Click Set Startup Projects.
c. In Solution from
d. Click Action and choose Start from the Multiple Startup Projects grid, on the line that corresponds to the server project also on the line that corresponds to the client project, click Action and choose Start.
e. Finally click OK.

In the App.xaml, in the method Application_Startup you can choose, which page you want to initially display.

Ans: In straight way you can''t create a subimage from an existing image. Here you just clip an image, Clipping is just different from Cropping. In clipping, first you have to dictate which part of the images to draw and later you have to remove all but the desired part of the image. Silverlight does not support cropping.
Q. How does Silverlight 2 differ from Adobe Flash?
Ans: As I am from .Net background so in my views you can get C# / Vb.net compiled code but in Flash there is only action script.
You can find difference in depth at : http://silverlight.net/forums/t/3015.aspx

Q. Can you elaborate how to start a silverlight application with Visual Studio?
Ans : You can find a fully described article from http://www.silverlightclub.com/resources/1858-silverlight-lets-start-building-applications.aspx.aspx
In the following step(s) I am giving the ideas all about:
1.Create a project:Here you just start your visual studio, Select your programming language [C#/VB], Choose Silverligh Template give the name and save it.
2. Adding SIlverlight COntrols:One thing is happened here, controls cannot dragged onto the designer, you can draw/drag the controls on XAML page.
(a) Naming to control:In this step just give the name to your silverligt control like for Button you can give name as : btnmySilverligtButton
(b)Adding event handlers to Silverlight controls:Here you can give the event handlers like for click etc.
(c)Testing Silverlight applications in Visual Studio:Now just press F5 and test your application
Q. What is the best place to start Silverlight application?
Ans: There is no hard and fast rule to start Silverlight application. Every developer can start as per his/her experience. like as per my case I always prefer Visual Studio. SO, in my view Visual Studio is the best place to start with Silverlight2 applications.Microsoft provides templates for creating Silverlight applications and libraries in C# and Visual Basic.

Today I want to share my words of Journey with DNS from a Member to a Webmaster.
My journey with DNS is started on 7/19/2008 5:11:57 PM. I have registered with Dotnetspider.com a MicroSoft.Net community as a new member with profile Gaurav Arora
As I was a very new in this community site I was not aware from rules/regulations also, “to err is human” so, its natural that I did mistakes. I am technical and know how to do Techie stuffs but not aware from the right way. In this period I have met many diamond members and other Sr. members who guided me "How to present stuffs in DNS?".
I met with Raghav he guided me lot of stuffs. As time passed away I got matured in DNS and Raghav found me suitable for Editorial work and he selected me as an Editor for DNS. This is the truning point of my life in DNS. Afterwards, Admins of DNS selected me Senior Editor.
Now I became a Diamond member and a Webmaster of DNS
Its just start of my Jorney, Tony who found me suitable for my work so, he gave me another responsibility of his another site Silverlight Club as a Webmaster
I am still trying to do my more efforts to prove myself also still learning more stuff.
The journey is still continue...
