# What is an endpoint in WCF? What are its three main parts?

In WCF, an **endpoint** is the communication point where a client connects to and interacts with a service. It defines **how** and **where** the service can be accessed.

### Three Main Parts of a WCF Endpoint

- **Address**

   - The location (URI or URL) where the service listens for messages.
   - Example: `http://localhost:8080/MyService`

- **Binding**

   - Specifies **how** to communicate with the service.
   - Defines protocols (HTTP, TCP), message encoding (text, binary), and security settings.

- **Contract**

   - Defines **what** functionality the service exposes.
   - Specifies the operations (methods) available to the client.

### Summary

- An endpoint = **Address + Binding + Contract**
- This allows clients to know where to connect, how to talk, and what actions they can perform.
