Specifies that an object can be initialized by using a non-default constructor syntax, and that a property of the specified name supplies construction information. This information is primarily for XAML serialization.

Thetype exposes the following members.
|ConstructorArgumentAttribute||Initializes a new instance of the class.|
|Equals||Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)|
|GetHashCode||Returns the hash code for this instance. (Inherited from Attribute.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|IsDefaultAttribute||When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)|
|Match||When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|_AttributeGetIDsOfNames||Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)|
|_AttributeGetTypeInfo||Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)|
|_AttributeGetTypeInfoCount||Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)|
|_AttributeInvoke||Provides access to properties and methods exposed by an object. (Inherited from Attribute.)|
This attribute specifies that the associated property can be initialized by a constructor parameter and should be ignored for XAML serialization if the constructor is used to construct the instance. This provides better round trip representations for parameterized constructor syntax rather than default constructor instantiation plus specific attributes.
A framework can potentially support preserving markup extension usages and reconstituting them rather than relying on ProvideValue output in the object tree for serialization. In this case, the information is useful during serialization for producing an accurate representation of the typical markup extension usage. For more information about markup extensions, see Markup Extensions for XAML Overview.
In order to be valid for a attribution, a type's public non-default constructor must support exactly one parameter. The name of the parameter must correspond to a read/write property. The property must be otherwise serializable. You use this attribute to create the correspondence between the name of the parameter in the constructor, and the property. Specifically, you apply this attribute to the property-level definition of the connecting read/write property.
Consumers of may throw in cases where ArgumentName does not resolve to type backing, or when applied to a type that does not have the appropriate construction arguments and arity.
In previous versions of the .NET Framework, this class existed in the WPF-specific assembly WindowsBase. In .NET Framework 4, is in the System.Xaml assembly. For more information, see Types Migrated from WPF to System.Xaml.
