Defines policy for code elements the containing attribute is applied to.

Syntax

<AttributeImplies Activate="policy_type"
                  Browse="policy_type"
                  Dynamic="policy_type"
                  Serialize="policy_type"
                  DataContractSerializer="policy_setting"
                  DataContractJsonSerializer="policy_setting"
                  XmlSerializer="policy_setting"
                  MarshalObject="policy_setting"
                  MarshalDelegate="policy_setting"
                  MarshalStructure="policy_setting" />

Attributes and Elements

The following sections describe attributes, child elements, and parent elements.

Attributes

Attribute	Attribute type	Description
`Activate`	Reflection	Optional attribute. Controls runtime access to constructors to enable activation of instances.
`Browse`	Reflection	Optional attribute. Controls querying for information about program elements, but does not enable any runtime access.
`Dynamic`	Reflection	Optional attribute. Controls runtime access to all type members, including constructors, methods, fields, properties, and events, to enable dynamic programming.
`Serialize`	Serialization	Optional attribute. Controls runtime access to constructors, fields, and properties, to enable type instances to be serialized and deserialized by libraries such as the Newtonsoft JSON serializer.
`DataContractSerializer`	Serialization	Optional attribute. Controls policy for serialization that uses the System.Runtime.Serialization.DataContractSerializer class.
`DataContractJsonSerializer`	Serialization	Optional attribute. Controls policy for JSON serialization that uses the System.Runtime.Serialization.Json.DataContractJsonSerializer class.
`XmlSerializer`	Serialization	Optional attribute. Controls policy for XML serialization that uses the System.Xml.Serialization.XmlSerializer class.
`MarshalObject`	Interop	Optional attribute. Controls policy for marshaling reference types to Windows Runtime and COM.
`MarshalDelegate`	Interop	Optional attribute. Controls policy for marshaling delegate types as function pointers to native code.
`MarshalStructure`	Interop	Optional attribute. Controls policy for marshaling value types to native code.

All attributes

Value	Description
policy_setting	The setting to apply to this policy type. Possible values are `All`, `Auto`, `Excluded`, `Public`, `PublicAndInternal`, `Required Public`, `Required PublicAndInternal`, and `Required All`. For more information, see Runtime Directive Policy Settings.

Child Elements

None.

Parent Elements

Element	Description
<Type>	Applies reflection policy to a type and all its members.

Remarks

The <AttributeImplies> element is used if its containing type is an attribute (that is, a class derived from System.Attribute). If the attribute is applied to a particular program element, the policy defined by the <AttributeImplies> element applies to that program element.

The reflection, serialization, and interop attributes are all optional, although at least one should be present.
