Type '{0}' is not usable as an object element
Type '{0}' is not usable as an object element because it is not public or does not define a public parameterless constructor or a type converter.
This error occurs when you attempt to instantiate a type by using element syntax, but the type does not have a public constructor, a type converter, or is not public. This may be caused by using an abstract type.
This error is raised when the file is a well-formed XAML document, but contains one or more type mismatches.
Error ID: XAML0507
To correct this error
- Use a type which provides a public constructor or a type converter. If the type is abstract, use a derived concrete type.
To correct this error
- If the error is raised because of your custom type, consider providing a public constructor or a type converter for the type.
Example
The following code example shows an attempt to create a Freezable object by using element syntax. The constructor for the Freezable type is protected. Uncomment the declaration to raise error XAML0507.
<!-- Uncomment the following line to raise error XAML0507. -->
<!-- <Button> <Freezable /> </Button> -->
