ServiceDisc

ServiceDisc is a library for hosting and communicating between services. Service discovery is done through a common data collection. Each service will register in the collection when it's hosted to make it a simple process to reach it.

ServiceDisc requires common storage between clients and services. Currently Azure Storage is implemented, and in-memory storage for testing. Other storage can be implemented using the IServiceDiscConnection interface which requires methods to register/unregister services and to send/receive queue messages.

There are two methods of communicating between services. Web API which will create a Web API controller to host the services, and a queue service which will listen to other services and reply through message queues. Queue service is default, this can be updated through the ServiceDiscClient.ServiceHostFactory property (setting it to WebApiServiceHostFactory will host the services with Web API instead).

Installing from NuGet

Install-Package ServiceDisc

Example

// Create a client, used for hosting and connecting to services.
// Pass an instance of AzureStorageServiceDiscConnection to store services in Azure,
// to enable having clients and services on different computers.
var serviceDisc = new ServiceDiscClient();

// Create an instance of a class to host as a service.
var helloService = new HelloService();

// Host the service and register it in the ServiceDisc.
// The service will now be known to other clients with the same IServiceDiscConnection
await serviceDisc.HostAsync<IHelloService>(helloService);

// Create a client for communicating with the IHelloService.
// This operation will search the common storage for services implementing IHelloService
// and create a proxy class to communicate with it.
var helloServiceClient = await serviceDisc.GetAsync<IHelloService>(serviceName);

// Send and receive a message from the service.
var world = helloServiceClient.Hello();
