1. Why do we need to get the metadata on client side? Sometimes the client need to programmatically verify whether a participant endpoint (identified by its address) supports a participant contract/operations. for example, imagine an application where the End User specifies or configures the application during setup to consume and interact with a service. if the service does not support the required contracts, the application shocould alert the user t

WCF enables communication between applications in the network system. The communication between applications is implemented by an endpoint
components. In terms of WCF, this component is called a WCF Service. In a more general sense, the WFC service is the software responsible for communicating with the outside world.
A WCF Service consists of the following three parts:
Service Class: A class marked with the [servicecontract] attribute, which may contain multiple methods. Except for marking some unique attributes of WCF, this class is no different from general classes.HOST: it can be an application, such as a Windows service. It i
Vector concept:
If the endpoint of a line segment is ordered, we convert this line segment into a directed line segment ).If the start point P1 of the directed line P1P2 is at the coordinate origin, we can call it vector P2.
Vector addition and subtraction:
Set two-dimensional vector p = (x1, Y1), q = (X2, Y2 ),Vector Addition is defined as: p + q = (X1 + X2, Y1 + y2 ),Vector Subtraction is defined as p-q = (x1-X2, Y1-Y2 ).Obviously, p + q = q + p, p-
2.6. endpoints, pipelines, and interfaces
These three concepts are confusing during USB development. For USB operations in real environments, endpoints, pipelines, and interfaces cannot be ignored. The relationship between these three concepts is 2-6-1;
The USB physical endpoint. In the NXP lpc2478 USB, there are up to 32 physical endpoints, each endpoint from 0 to 31 has a fixed transmission mode (I/out).
Concept of vector:
If the endpoint of a line segment is ordered, we convert this line segment into a directed line segment ).If the start point P1 of the directed line P1P2 is at the coordinate origin, we can call it vector P2.

the management system. Therefore, the communication task must be delegated to different components. In terms of WCF, this component is called a WCF Service. In a more general sense, the WFC service is the software responsible for communicating with the outside world.

When you are finished using the socket, re
1. Enumerate the USB STM32 as HID devices.
2. STM32 uses 3 endpoints, endpoint 0 for enumeration, endpoints 1 and 2 for data sending and receiving.
3. The endpoint length is 64, that is, a maximum of 64 bytes of data can be transmitted in a single pass.
4. STM32 obtains the data from the host computer and returns the data via USB and prints out the data.

Name: specifies the type of service agreement implementation. It is a fully qualified name (namespace and type name)
BehaviorConfiguration: Specifies the name of the service behavior element found in the behaviors element. The node in the corresponding behaviors is the serviceBehaviors node.

WCF is a framework used to build service-oriented applications. WCF is a runtime and a group of APIs used to create a system for sending messages between a service and a client. Based on the concept of message-based communication, WCF can represent any content of a message in a unified manner in the programming model.
Message
A message is an independent data unit. It may consist of several parts, including the message body and message header.
Service
