[DataContract] attribute specifies the data, which is to serialize (in short conversion of structured data into some format like Binary, XML etc.) and deserialize(opposite of serialization) in order to exchange between the client and the Service.

How do I get a Microservice version?

Microservice Versioning

  1. For MAJOR version change, the consumers have to be changed.
  2. For MINOR version change (backwards compatible), only the consumer(s) that requires the added functionality needs to change.
  3. For PATCH version change, it’s optional and would probably be seamless for any consumers to make use of it.

When should I use DataMember attribute?

Data Member are the fields or properties of your Data Contract class. You must specify [DataMember] attribute on the property or the field of your Data Contract class to identify it as a Data Member. DataContractSerializer will serialize only those members, which are annotated by [DataMemeber] attribute.

A datacontract is a formal agreement between a client and service that abstractly describes the data to be exchanged. In WCF, the most common way of serialization is to make the type with the datacontract attribute and each member as datamember.

What is the WCF versioning model?

Similar to data contract versioning, service contract versioning also involves adding, changing, and removing operations. By default, the name of a service contract is the name of the interface.

What is version tolerance in WCF?

This kind of versioning is based on the version tolerant behavior of the WCF framework. This versioning approach fully relies on backward compatibility for as long as possible and avoids formal contract and endpoint versioning until compatibility is broken.
