Apply the DataContractAttribute attribute to types (classes, structures, or enumerations) that are used in serialization and deserialization operations by the DataContractSerializer. If you send or receive messages by using the Windows Communication Foundation (WCF) infrastructure, you should also apply the DataContractAttribute to any classes. The DataContractSerializer is designed to serialize data contract. Attribute has been applied. Apply to types supported by the Data Contract. Okay, I LIKE and PREFER Data Contracts versus Serializable. I have built and tested many scenarios and the tests work great and I like the level of control.

Apply the DataContractAttribute attribute to types (classes, structures, or enumerations) that are used in serialization and deserialization operations by the. If you send or receive messages by using the Windows Communication Foundation (WCF) infrastructure, you should also apply the DataContractAttribute to any classes that hold and manipulate data sent in messages. For more information about data contracts, see. You must also apply the to any field, property, or event that holds values you want to serialize.

By applying the DataContractAttribute, you explicitly enable the to serialize and deserialize the data. A data contract is an abstract description of a set of fields with a name and data type for each field. The data contract exists outside of any single implementation to allow services on different platforms to interoperate. Manually Uninstall Gfi Endpoint Security Agent there.

Mar 22, 2016 DataContract versus Serializable. >>If I use the DataContract to establish serialization. The DataContractAttribute attribute should not be.

As long as the data passed between the services conforms to the same contract, all the services can process the data. This processing is also known as a loosely coupled system. A data contract is also similar to an interface in that the contract specifies how data must be delivered so that it can be processed by an application. For example, the data contract may call for a data type named 'Person' that has two text fields, named 'FirstName' and 'LastName'. To create a data contract, apply the DataContractAttribute to the class and apply the to any fields or properties that must be serialized.

When serialized, the data conforms to the data contract that is implicitly built into the type. If you are exchanging data with other services, you must describe the data contract. For the current version of the, an XML schema can be used to define data contracts. (Other forms of metadata/description could be used for the same purpose.) To create an XML schema from your application, use the with the /dconly command line option. When the input to the tool is an assembly, by default, the tool generates a set of XML schemas that define all the data contract types found in that assembly. Conversely, you can also use the Svcutil.exe tool to create Visual Basic or C# class definitions that conform to the requirements of XML schemas that use constructs that can be expressed by data contracts. In this case, the /dconly command line option is not required.

If the input to the Svcutil.exe tool is an XML schema, by default, the tool creates a set of classes. If you examine those classes, you find that the DataContractAttribute has been applied. You can use those classes to create a new application to process data that must be exchanged with other services. You can also run the tool against an endpoint that returns a Web Services Description Language (WSDL) document to automatically generate the code and configuration to create an Windows Communication Foundation (WCF) client. The generated code includes types that are marked with the DataContractAttribute. A data contract has two basic requirements: a stable name and a list of members.

The stable name consists of the namespace uniform resource identifier (URI) and the local name of the contract. By default, when you apply the DataContractAttribute to a class, it uses the class name as the local name and the class's namespace (prefixed with 'as the namespace URI. You can override the defaults by setting the and properties. You can also change the namespace by applying the to the namespace. Use this capability when you have an existing type that processes data exactly as you require but has a different namespace and class name from the data contract.
