IdentityServer4 discovery document returns 404

Question

I am following the quick start for ID Server 4 with one exception that I am working on a Mac with .NET Core 2.1.302. Somehow when I navigate to http://localhost:5000/.well-known/openid-configuration I get a 404:

info: Microsoft.AspNetCore.Hosting.Internal.WebHost[1]
      Request starting HTTP/1.1 GET http://localhost:5000/.well-known/openid-configuration  
info: Microsoft.AspNetCore.Hosting.Internal.WebHost[2]
      Request finished in 0.108ms 404

Here are the steps that I took:

Created a new MVC project dotnet new mvc
Added ID Server dotnet add package IdentityServer4

Modified my service configuration by adding

    services.AddIdentityServer()
        .AddDeveloperSigningCredential()
        .AddInMemoryApiResources(Config.GetApiResources())
        .AddInMemoryClients(Config.GetClients());

Created Config.cs with:

public static IEnumerable<ApiResource> GetApiResources()
{
    return new List<ApiResource>
    {
        new ApiResource("api1", "My API")
    };
}

public static IEnumerable<Client> GetClients()
{
    return new List<Client>
    {
        new Client
        {
            ClientId = "client",

            // no interactive user, use the clientid/secret for authentication
            AllowedGrantTypes = GrantTypes.ClientCredentials,

            // secret for authentication
            ClientSecrets =
            {
                new Secret("secret".Sha256())
            },

            // scopes that client has access to
            AllowedScopes = { "api1" }
        }
    };

When I navigate to http://localhost:5000/.well-known/openid-configuration I get a 404 instead of the discovery document. Any ideas?

Missing from your list of of steps is adding UseIdentityServer inside of your Startup's Configure method. It's covered in the official docs and looks something like this:

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    // ...

    app.UseIdentityServer();
    app.UseMvc(...);
}

UseIdentityServer adds the IdentityServer middleware into the ASP.NET Core pipeline. One of its responsibilities is to serve up the .well-known endpoints.
