Question

Why does the ObjectDataProvider not recogize ‘local:Customer’ in this example?

When I type

<local:

I get intellisense for ‘Customer’ so it should work. I have no code-behind in this example.

XAML:

<Window x:Class='TestDataTemplate124.Window1'     xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'     xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'     xmlns:local='clr-namespace:TestDataTemplate124'     Title='Window1' Height='300' Width='300'>     <Window.Resources>         <ObjectDataProvider x:Key='Customers'                             ObjectType='x:Type local:Customer'                             MethodName='GetAllCustomers'/>     </Window.Resources>     <StackPanel>         <ListBox DataContext='{StaticResource Customers}' ItemsSource='{Binding}'>             <ListBox.ItemTemplate>                 <DataTemplate>                     <StackPanel Orientation='Horizontal'>                         <TextBlock Text='{Binding FirstName}'/>                         <TextBlock Text=' '/>                         <TextBlock Text='{Binding LastName}'/>                         <TextBlock Text=' ('/>                         <TextBlock Text='{Binding Age}'/>                         <TextBlock Text=')'/>                     </StackPanel>                 </DataTemplate>             </ListBox.ItemTemplate>         </ListBox>     </StackPanel> </Window> 

Customer.cs:

using System.Collections.ObjectModel;  namespace TestDataTemplate124 {     public class Customer     {         public string FirstName { get; set; }         public string LastName { get; set; }         public int Age { get; set; }          public static ObservableCollection<Customer> GetAllCustomers()         {             ObservableCollection<Customer> customers = new ObservableCollection<Customer>();             customers.Add(new Customer() { FirstName = 'Jim', LastName = 'Smith', Age = 23 });             customers.Add(new Customer() { FirstName = 'John', LastName = 'Jones', Age = 22 });             customers.Add(new Customer() { FirstName = 'Jay', LastName = 'Anders', Age = 21 });             return customers;         }     } }

‘x:Type’ is a markup extension, so enclose it in curly braces:

ObjectType='{x:Type local:Customer}'
