我习惯于创建一个.Net Framework控制台应用程序,并通过WCF服务从头开始使用类库()公开 Add(int x,int y)函数。网络框架)。然后,我使用控制台应用程序在服务器内代理调用此功能。
I am used to creating a .Net Framework console application and exposing a Add(int x, int y) function via a WCF service from scratch with Class Library (.Net Framework). I then use the console application to proxy call this function within the server.
但是,如果我使用控制台应用程序(.Net Core)和类库(.Net Core) System.ServiceModel不可用。我做了一些谷歌搜索,但是在这种情况下我还没有弄清楚是什么替代了 WCF。
However if I use Console App (.Net Core) and a Class Library (.Net Core) the System.ServiceModel is not available. I have done some Googling but I haven't figured out what "replaces" WCF in this instance.
如何公开 Add(int类库中的x,int y)函数到.Net Core中所有的控制台应用程序?我看到了System.ServiceModel.Web,由于这是跨平台的,所以我必须创建一个RESTful服务吗?
How do I expose a Add(int x, int y) function within a class library to a console application all within .Net Core? I see System.ServiceModel.Web, and since this is trying to be cross platform do I have to create a RESTful service?
推荐答案.NET Core不支持WCF,因为它是Windows特定的技术,而.NET Core应该是跨平台的。 如果要实现进程间通信,请考虑尝试此项目。 它允许以WCF样式创建服务:
WCF is not supported in .NET Core since it's a Windows specific technology while .NET Core is supposed to be cross-platform. If you are implementing inter-process communication consider trying this project out. It allows creating services in WCF style:
步骤1-创建服务合同
public interface IComputingService { float AddFloat(float x, float y); }步骤2:实施服务
class ComputingService : IComputingService { public float AddFloat(float x, float y) { return x + y; } }第3步-在控制台应用程序中托管服务
Step 3 - Host the service in Console application
class Program { static void Main(string[] args) { // configure DI IServiceCollection services = ConfigureServices(new ServiceCollection()); // build and run service host new IpcServiceHostBuilder(services.BuildServiceProvider()) .AddNamedPipeEndpoint<IComputingService>(name: "endpoint1", pipeName: "pipeName") .AddTcpEndpoint<IComputingService>(name: "endpoint2", ipEndpoint: IPAddress.Loopback, port: 45684) .Build() .Run(); } private static IServiceCollection ConfigureServices(IServiceCollection services) { return services .AddIpc() .AddNamedPipe(options => { options.ThreadCount = 2; }) .AddService<IComputingService, ComputingService>(); } }步骤4-从客户端进程调用服务
Step 4 - Invoke the service from client process
IpcServiceClient<IComputingService> client = new IpcServiceClientBuilder<IComputingService>() .UseNamedPipe("pipeName") // or .UseTcp(IPAddress.Loopback, 45684) to invoke using TCP .Build(); float result = await client.InvokeAsync(x => x.AddFloat(1.23f, 4.56f));更多推荐
什么可以替代.Net Core中的WCF?
