Data Contract Overview
By default, WCF uses the serialization engine, called the data Contract serializer, to serialize and deserialize data (and convert it to and from XML).
All. Net framework primitive types, such as Integer and string, and some types that are considered primitives, such as datetime and XmlElement, can be serialized and considered to have a default data
There was also a chapter "WCF Overview", which is a summary of the text, not "copied", directly from chapter two.Of course, learning WCF still needs some foundation. https://msdn.microsoft.com/zh-cn/hh148206 This is the "original", like WCF can download it by itself.WCF Simple terms:Message: The message is a separate unit of data, mainly composed of the message header and message body, the introduction of the time I understand it simple: to send a message, is to call a method, the specific later

The operation contract is used to define the system behavior, and the behavior of the system is described in detail according to the change of the object state in domain model;
A use case is a model that describes the behavior of a system, but if the use case is not clearly described, it is supplemented in the Operation contract.
Typically a use case has multiple operations, and an operation requires an
Because there is no Apple computer, so the use of Linux in this environment to operate, windows can, but did not try, also read a lot of articles, said there will be a lot of problems.
This article addresses the following issues:
1.geth after upgrading to 1.6 version, no longer use eth.getcompilers () or ADMIN.SETSOLC () and so on by JS to compile in real-time, but with the ABI contract interface binary representation. Compile by converting to JSON to
When a client references a WCF Service, a unique namespace must be defined for the service. By default, the classes used in this service are imported into this namespace. In this way, when you reference the same data contract in different services, you will encounter a problem: On the client, the same data contract is imported into different namespaces and cannot be converted.
In the following example, the
In WCF, all services are called externally through contracts. A contract is a platform-independent and standard method for describing services. Currently, four types of contracts are defined in WCF.

Service Contract)
Describes the operations that a client can call a service.

Write the first Java chain code programIn the previous section, you are already familiar with how to build, run, deploy, and invoke chain code, but have not yet written any Java code.In this section, you will use the Eclipse IDE, a Gradle plug-in for Eclipse, and a Java chain Code framework project called Chaincodetutorial to write the first Java chain Code program. You'll get the skeleton code from the GitHub repository I created for this tutorial, import that code into Eclipse, add code to mak
Contract: A contract is like a protocol between one or more programs. A contract defines some conventions that an application must follow when it interacts with other programs or windows.
