9.5 Involvement in 2019–20 Hong Kong protests. 3.3 Station facilities, amenities and services. The MTR has served as a model for some newly built systems, particularly in mainland China. There are continual debates regarding how and where to expand the MTR network. The MTR was immediately popular with residents of Hong Kong as a result, subsequent lines have been built to cover more territory. Construction started soon after the release of the study, and the first line opened in 1979. The integration of the Octopus smart card fare-payment technology into the MTR system in September 1997 has further enhanced the ease of commuting on the MTR.Ĭonstruction of the MTR was prompted by a study, released in 1967, commissioned by the Government of British Hong Kong to find solutions to the increasing road congestion problem caused by the territory's fast-growing economy. As of 2018, the MTR has a 49.3 per cent share of the franchised public transport market, making it the most popular transport option in Hong Kong. It consistently achieves a 99.9 per cent on-time rate on its train journeys. Under the government's rail-led transport policy, the MTR system is a common mode of public transport in Hong Kong, with over five million trips made in an average weekday. The system included 230.9 km (143.5 mi) of rail in 2018 with 166 stations, including 98 heavy rail stations and 68 light rail stops. Operated by the MTR Corporation Limited (MTRCL), it consists of heavy rail, light rail, and feeder bus service centred on a 10-line rapid transit network serving the urbanised areas of Hong Kong Island, Kowloon, and the New Territories. The Mass Transit Railway ( MTR) is a major public transport network serving Hong Kong. 1,432 mm ( 4 ft 8 + 3⁄ 8 in) almost-standard gauge (all other lines). 1,435 mm ( 4 ft 8 + 1⁄ 2 in) standard gauge (East Rail line, Tuen Ma line, South Island line, Light Rail and line extensions after 2014). Using Create returns a request handle, which can be used to set headers and other attributes of the request before it is sent. The request client can be used to create requests (returning a RequestHandle, which must be disposed after the request completes) or it can be used directly to send a request and get a response (asynchronously, of course). 
To create a client factory, call bus.CreateClientFactory or host.CreateClientFactory - after the bus has been started.

If a consumer is sending the request, a new client should be created for each message (and is handled automatically if you're using a dependency injection container and the container registration methods). There are advantages to each approach, although it's typically best to create a request client and use it if possible. Public class CheckOrderStatusConsumer : IConsumer Īs shown, the client factory can create a request client, or it can create a request directly.
In this example, an order status check is being created. To get started, the message contracts need to be created. Additionally, multiple asynchronous requests can be executed at once, reducing the overall execution time to that of the longest request.

By using Tasks and the async and await keywords, developers can write procedural code and avoid the complex use of callbacks and handlers. NET developers, C# with TPL makes it easier to program applications that call services asynchronously. While in many cases it is best to avoid request/response use in distributed applications, particularly when the request is a command, it is often necessary and preferred over more complex solutions.įortunately for. In a distributed system, this can increase the latency of an application since the service may be hosted in another process, on another machine, or may even be a remote service in another network. Request/response is a common pattern in application development, where a component sends a request to a service and continues once the response is received.
