WebHost is an internal class from Microsoft.AspNetCore.Hosting.Internal. Correct answer is <new TestServer(new WebHostBuilder()...>

I agree. Correct answer is: TestServer WebHostBuilder Code: (...) // Configure the in-memory test server, and create an HttpClient for interacting with it var server = new TestServer(webHostBuilder); HttpClient client = server.CreateClient(); // Send requests just as if you were going over the network var response = await client.GetAsync("/"); response.EnsureSuccessStatusCode(); var responseString = await response.Content.ReadAsStringAsync(); Assert.Equal("Hello World!", responseString); Ref: https://andrewlock.net/converting-integration-tests-to-net-core-3/
