How to host simple REST service using .NET core

Question

I'm trying to migrate WCF (WebHttpBinding) to .NET core. Because, WebHttpBinding is not available in coreWCF.

Here my server code to host the REST service:

var builder = WebApplication.CreateBuilder();
var app = builder.Build();
app.Urls.Add("http://localhost:9000/MyService");
app.MapGet("/Test", () => "Hello World!");
app.Run();

Here my client code to call the service:

using HttpClient client = new();
client.DefaultRequestHeaders.Accept.Clear();
var reply = await client.GetStringAsync("http://localhost:9000/MyService/Test");

The client code works good if the service is developed using WCF (WebHttpBinding). However, above server-code does not work.

How should I create REST service, so that the client-code can access?

Answer 1

Can you try creating the service like this?

var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();
app.Urls.Add("http://localhost:9000");
app.MapGet("/MyService/Test", () => "Hello World!");

app.Run();

The URL should not contains paths.
