Using the ObjectDataProvider always throws an exception...

The following code in C# always throws an exception at the 3rd Line.....+
$exception {"ObjectDataProvider can only be assigned an ObjectType or an
ObjectInstance, not both."} System.Exception
{System.InvalidOperationException}
==============================================================================

LoginScreenDataSource mLoginScreen = new LoginScreenDataSource();
ObjectDataProvider LoginProvider =
(ObjectDataProvider)FindResource("ods_LoginScreenDataSource");
LoginProvider.ObjectInstance = new LoginScreenDataSource();
===============================================================================
LoginScreenDataSource is a Class object
ods_LoginScreenDataSource is in the XAML file defined as
<Window.Resources>
<ObjectDataProvider x:Key="ods_LoginScreenDataSource" ObjectType="{x:Type
ds:LoginScreenDataSource}"/>

Any ideas ???
Cheers Desmond.

As specified by the error message, you cannot specify BOTH the
ObjectType and the ObjectInstance...

ObjectType indicates to the ObjectDataProvider what type of object to
instantiate (if no object instance is supplied).

ObjectInstance is there to allow you to feed an object instance to the
ObjectDataProvider, so it does not have to create its own...
