Exception registering JsonSerializerSettings conflicting with AppMetrics

[jchannon]

public void ConfigureServices(IServiceCollection services)
{
  services.AddSingleton(new JsonSerializerSettings { ContractResolver = new DefaultContractResolver { NamingStrategy = new CamelCaseNamingStrategy() }, NullValueHandling = NullValueHandling.Ignore});
}

Using Autofac I got the below error:

Cannot choose between multiple constructors with equal length 1 on type 'App.Metrics.Formatters.Json.Serialization.HealthStatusSerializer'. Select the constructor explicitly, with the UsingConstructor() configuration method, when the component is registered.

Removing Autofac and just using ASP.NET DI I got a exception about HealthStatusserializer and I think IClock

App Metrics has never registered JsonSerializerSettings. The older version of HealthStatusSerializer had two ctors, one of which had JsonSerializerSettings injected so DI could not work out which ctor to use.

This is no longer the case

This issue was moved to AppMetrics/AspNetCoreHealth#2
