ASP.NET Core OData 8.0 and AddServicePrototype

[jeffreyrjones-tc]

How do I add a service prototype with ASP.NET Core OData 8.0. I need to override the ODataMessageReaderSettings & ODataMessageWriterSettings so that I can change the MessageQuotas.

I used to do the following in v7.5, but MapODataServiceRoute is no longer available so I'm not sure how to add service prototypes.

            routeBuilder.MapODataServiceRoute(
                routeName: "odata",
                routePrefix: "odata",
                configureAction: containerBuilder => containerBuilder
                    .AddDefaultODataServices()
                    .AddService(Microsoft.OData.ServiceLifetime.Singleton,
                                typeof(IEdmModel),
                                serviceProvider => GetEdmModel())
                    .AddServicePrototype(new ODataMessageReaderSettings
                    {
                        MessageQuotas = new ODataMessageQuotas
                        {
                            MaxNestingDepth = 10,
                            MaxOperationsPerChangeset = 100000,
                            MaxPartsPerBatch = 100000,
                            MaxReceivedMessageSize = 2147483648
                        }
                    })
                    .AddServicePrototype(new ODataMessageWriterSettings
                    {
                        MessageQuotas = new ODataMessageQuotas
                        {
                            MaxNestingDepth = 10,
                            MaxOperationsPerChangeset = 100000,
                            MaxPartsPerBatch = 100000,
                            MaxReceivedMessageSize = 2147483648
                        }
                    })
                    .AddService(Microsoft.OData.ServiceLifetime.Scoped,
                                typeof(ODataBatchHandler),
                                (IServiceProvider serviceProvider) => new SpawnScopeODataBatchHandler(log))
                    .AddService(Microsoft.OData.ServiceLifetime.Singleton,
                                typeof(IEnumerable<IODataRoutingConvention>),
                                serviceProvider => ODataRoutingConventions.CreateDefaultWithAttributeRouting("odata", routeBuilder))
            );

I was going to override the DefaultContainerBuilder, but in v8.0 DefaultContainerBuilder is tagged as internal.

Then I was just going to copy the source for DefaultContainerBuilder to MyContainerBuilder, but I couldn't register MyContainerBuilder because configuration.UseCustomContainerBuilder is gone in ODATA v8.0
