What is WCF mex endpoint?
MEX endpoints are special endpoints that allow clients to receive the service’s metadata by using SOAP messages instead of only http get requests(ie httpGetEnabled=”true”). You can create MEX endpoint that can be accessed through http, https, tcp, and even named pipes.
How do you define an endpoint in WCF?
Each endpoint consists of the following:
- Address: The address uniquely identifies the endpoint and tells potential consumers of the service where it is located.
- Binding: The binding specifies how to communicate with the endpoint.
- Contracts: The contract outlines what functionality the endpoint exposes to the client.
What is metadata exchange in WCF?
WCF services use metadata to describe how to interact with the service’s endpoints so that tools, such as Svcutil.exe, can automatically generate client code for accessing the service. Most of the types that make up the WCF metadata infrastructure reside in the System. ServiceModel. Description namespace.
How can metadata endpoint be exposed in WCF?
We can expose it by choosing one of the following ways:
- In the configuration file, by enabling metadata exchange as follows:
- ServiceHost can expose a metadata exchange endpoint to access metadata at runtime. using (ServiceHost host = new ServiceHost(typeof(MyService))) {
What should contain an endpoint in WCF?
The endpoint is the fusion of the address, contract, and binding. Every endpoint must have all three elements, and the host exposes the endpoint.
What are the components of an endpoint in WCF?
Clients find the end points through three components like service contract, binding, and address.
Can WCF service have multiple endpoints?
Sometimes in our mind the question arise; can we implement multiple service contract in WCF service? And the answer is, Yes we can. Service class implement multiple service interfaces, and then expose each service using a different endpoint.
Can we have multiple endpoints in WCF?
WCF allow us to give multiple base addresses for each type of protocol. And at the run time corresponding endpoint will take the base address. So you can expose IService1 on multiple EndPoint with more than one binding as below.
What is a metadata endpoint?
Metadata endpoints are similar to other service endpoints in that they have an address, a binding, and a contract, and they can be added to a service host through configuration or in code. To enable publishing metadata endpoints, you must add the ServiceMetadataBehavior service behavior to the service.
How many ways are there to download service metadata from the WCF service?
You can retrieve service metadata using WS-MetadataExchange or HTTP/GET requests by using the ServiceModel Metadata Utility Tool (Svcutil.exe) tool and passing the /target:metadata switch and an address. Svcutil.exe downloads the metadata at the specified address and saves the file to disk.
How many endpoints are there in WCF?
Endpoints in WCF End point consists of three components. 2) Bindings : A binding that specifies how a client can communicate with the endpoint.
