How to support multiple authentication scheme in Web API Core 2?

Question

I'm developing a web api core 2.0 project.

I need support two authorization types: jwt and basic.

Inside my ConfigureServices method I've added this code:

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme).AddJwtBearer((options) =>
{
    options.Authority = $"...";
    options.Audience = "...";
});

services.AddAuthentication(BasicAuthenticationDefaults.AuthenticationScheme)
.AddBasicAuthentication(credentials =>
Task.FromResult(
   credentials.username == "username"
   && credentials.password == "password"));

Inside my Configure method I've added this code:

app.UseAuthentication();
app.UseMvc();

And finally I've added AuthorizeAttribute on my controller:

[Authorize]
public class MioController : Controller
{ ... }

Actually work only the last authentication specified on ConfigureServices.

How can I support both authentication types? Thanks

Note: I'm using this NuGet package for basic authentication Bazinga.AspNetCore.Authentication.Basic.

try Adding your authentication service in one chain

services
.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddJwtBearer((options) =>
{
    options.Authority = $"...";
    options.Audience = "...";
})
.AddBasicAuthentication(credentials =>
{
    Task.FromResult(credentials.username == "username" && credentials.password == "password"));
}

and also on AuthorizeAttribute you can specify which Scheme you want to authenticate the request with

[Authorize(AuthenticationSchemes = BasicAuthenticationDefaults.AuthenticationScheme + ", " + JwtBearerDefaults.AuthenticationScheme)]
