I think the problem is that the People objects that you are trying to send are defined on the client side. The service is expecting the People objects that are defined on the service side - they are not the same thing.
Try sending a list of ServiceReference1.People instead of SilverlightApplication1.People and see if you get the same error.

In addition to Nigel's reply...
Since you're using the automagic proxy generator, then you
can look at the generated code on the client side:
1) Click on the client project in the Solution Explorer
2) Click the "Show All Files" button on the Solution Explorer's toolbar
3) Drill down the files tree from the service reference to find the
Reference.cs file - that will have the generated client-side classes
In the generated code, there should be the People class you should be using.
If it's not there, try using the DataContractAttribute on the server side:
[DataContract]
public class People
{
[DataMember]
public string name;
[DataMember]
public int age;
}
(don't forget to update the service reference on the client to get new
generated code!)

Mark,
It is there. Thanks for the extra info (Being able to look at the generated client-side class is really usefull) The problem is solved. Nigel's post was right. I apologize that I didn't mentioned it on the previous thread. But, there are 2 things I learned, besides these ones.
1. Starting with Net 3.51 it is not necessary to add the [Data Contract] anymore for know types.
2. It appears that SL 3 web services do not require to implement the interface

{
try
{
using (System.Drawing.Image objimage = System.Drawing.Image.FromStream(stream,true))
{
Bitmap objbitmap = new Bitmap(objimage);
MemoryStream str= SetImageSize(objbitmap);
Bitmap bitnew = new Bitmap(str);
IntPtr hBitmap = bitnew.GetHbitmap();
BitmapSource bmpSrc = Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero,
Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
DeleteObject(hBitmap);
imageOnlineUser.Source = bmpSrc;
if (this.ConnectDisconnect == false)
{
btnVideoShare.IsEnabled = false;
}
stream.Flush();
stream.Dispose();
GC.Collect();
}
}

You start by learning the language that you wish to use, usually by buying a book and studying hard. When you have a problem with your program you can post a question here and ask for help.

I appreciate your answer but there is no available book here in my country. If i buy it online i can't afford it. Thank you for your answer

According to your homepage your country is USA where you can buy books on every subject you may need. Secondly if you cannot afford to buy a book then I suggest you try some of the tutorials on the internet as you obviously have access to that. There are hundreds of articles here on The Code Project, and other sites, to get you started.
Your question is far too general for anyone here to give you a simple answer, you must do your own work first.

oh I'm sorry i did not notice that my country was in USA i will change it immediately sorry for the confusion sorry .... I may have an internet it is not good for playing video though .... again i an deeply apologize for the confusion of the country post homepage... I am not looking for a debate ...I appreciate that you have concern about my study habit... if you think this is just a shallow question then i will delete this thread after i figure how i can delete it... again i thank you and i apologize for the confusion

No, your question is fine. I was just trying to explain that what you are asking for cannot be answered in a forum like this, as it would take too long. If you read some of the introduction articles on the subject of your choice they will show you how to do the things you want to learn. Then when you find something that you have difficulty understanding, or that does not seem to work, you can post a question and people will try to help.

I understand thank you i'll just try searching for more resource

Assuming you want to use WPF since you asked in this forum...
The entire SDK is available free online, and it also is included
with Visual Studio:
Windows Presentation Foundation[^]
I always recommend reading the entire SDK TWICE, maybe
trying out some code the second time through. It's amazing how few
questions one will have if one knows the fundamentals...

Maybe your first question should have been : How can I find some resource to learn WPF?

I did do some research .....I did try some sample but this is the only topic that i had some difficulty ... But I would be happy if you can post some Thank you

This is far too wide a subject to post an answer here. Take a look at some of the WPF articles here on Code Project for further information.

Do you mean 'many' ? You just add them, one at a time. It's no different, no matter how many there are

To communicate between classes, use delegates.

What does this have to do with WPF, WCF or WF?

First of all, what you want is not possible. Second, if it was possible, it's plain that you're too dumb to do it. This is the WPF/WCF forum.

How to handle WPF datagrid row double click event? I tried with PreviewMouseClick. But it is getting throwed when clicked on header also.
Private Sub dbGrid_PreviewMouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Input.MouseButtonEventArgs) Handles dbGrid.PreviewMouseDoubleClick
If Not dbGrid.SelectedItem Is Nothing Then
MsgBox(DirectCast(DirectCast(DirectCast(dbGrid.SelectedItem, System.Object), System.Data.DataRowView).Row, System.Data.DataRow).ItemArray(0).ToString)
End If
e.Handled = True
End Sub
How to handle it only for datagrid row?

After I've hacked together my first WPF app today, I'd like to embark on a slightly more formal approach to continuing to learn WPF. What do you guys recommend?

I'd recommend that you knock something up using MVVM. It's a great pattern, and you'll find it helps you a lot later on.
