I know the documentation for the following is not up to date:

Jump Start: Creating a PocketPC Application - C#
Step 7: Calling the Web Service from the PocketPC Form

2. Add the following code to the btnGetOrders_Click event handler:

private void btnGetOrders_Click(object sender, System.EventArgs e)
{
// Turn the cursor into an hourglass
Cursor.Current = Cursors.WaitCursor;

// Instantiate the Web Service class
CustomerOrdersWS.CustomerOrdersWS_CSharp wsCustOrders =
new CustomerOrdersWS.CustomerOrdersWS_CSharp();

// Call the Web Service
DataSet dsOrders = wsCustOrders.GetOrdersByCustomerID(this.txtCustomerID.Text);
// Bind the result set to the DataGrid
this.grdOrders.DataSource = dsOrders.Tables[0];
// Restore the cursor to a pointer
Cursor.Current = Cursors.Default;
}

Can give me some guidance on updating this code to utilize an entity vs. dataset?

Thanks, Ted
