Displaying the data from a "LINQ to SQL database"

Question

I have created a LINQ to SQL database with a simple table/class with the following properties:
Counter
Subject
Description
About the Counter, how do I set the properties so it behaves like a "Counter". For each row I want it to automatically add new numbers like this:
1 Subject1 Decsription1
2 Subject2 Description2
3 Subject3 Description3...and so on for every new data inserted.
For now I have "Auto Generated Value=True" and "Primary Key=True". Is that the right way to go? What do I set for "Auto-Sync"? There are options like "Never, OnInsert, OnUpdate, Always".
I believe I've manage to do the coding for the insert part:
private void btnAddReminder_Click(object sender, RoutedEventArgs e)
DataClasses1DataContext db = new DataClasses1DataContext("db");
Reminders reminder = new Reminders();
reminder.Subject = txtSubject.Text;
reminder.Description = txtDescription.Text;
db.Reminders.InsertOnSubmit(reminder);
MessageBox.Show("Content added!");
Now first of all, is there a way I can display the database content directly in Visual Studio so I can see if I've manage to add any content in the table? I haven't yet find a way so far.
Second how do I get the content from the datatable row by row and display it in MainWindow.xaml? What would the code look like? For every row I would like it to be displayed like this:
1. Subject1
Description1
2. Subject2
Description2
3. Subject3
Description3
Is it possible to display "1. Subject1" in a Label. It should be sort of a headline.
Then would it be possible to display "Description1" in a TextBlock?
The idea is that Subject along with the number should have a larger font size, and the Description shoud be a bit smaller font size.

Yes, this means that the database takes care of the actual incrementation for you which is perfectly fine and probably what you want.

You need to an ItemsControl that can render all items in a collection somewhere in the MainWindow, e.g.:
<ItemsControl x:Name="ic">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel>
<StackPanel Orientation="Horizontal" Margin="0 0 0 10">
<TextBlock Text="{Binding Counter}"/>
<TextBlock Text=". "/>
<TextBlock Text="{Binding Subject}"/>
</StackPanel>
<TextBlock Text="{Binding Description}"/>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
The ItemTemplate (DataTemplate) of the ItemsControl defines the appearance of each item in its ItemsSource collection, i.e. a Reminders object in your case.
You then simply set the ItemsSource of the ItemsControl to the collection of Reminders object that you want to display in it in your code:
private void btnAddReminder_Click(object sender, RoutedEventArgs e)
DataClasses1DataContext db = new DataClasses1DataContext("db");
Reminders reminder = new Reminders();
reminder.Subject = txtSubject.Text;
reminder.Description = txtDescription.Text;
db.Reminders.InsertOnSubmit(reminder);
MessageBox.Show("Content added!");
ic.ItemsSource = db.Reminders;

First of all, please don't ask several questions in the same thread. Second, this is not a WPF question. If you are using a service-based database, you could select data from it from the Server Explorer in Visual Studio:
