Metadata not publishing with Core 2.0

I'm getting the following error when requesting the odata or odata/$metadata urls.

Cannot resolve scoped service 'Microsoft.OData.ODataSimplifiedOptions' from root provider.

You can modify your BuildWebHost method like this, which will solves your problem.

public static IWebHost BuildWebHost(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
        .UseStartup<Startup>()
        .UseDefaultServiceProvider(options => 
            options.ValidateScopes = false)
        .Build();

It works! Thx.

An alternative is to register the following to the container:

services.AddSingleton<ODataSimplifiedOptions>();
services.AddSingleton<ODataUriParserSettings>();
services.AddSingleton<UriPathParser>();

I'm facing another issue with the client generator.
The client is generated successfully, but when trying to retrieve any entity I get the following:
(i.e client.Logs.Execute())

"When writing a JSON response, a user model must be specified and the entity set and entity type must be passed to the ODataMessageWriter.CreateODataEntryWriter method or the ODataFeedAndEntrySerializationInfo must be set on the ODataEntry or ODataFeed that is being written."
