[severity:I'm unable to use this version] [regression] [worked-in:17.9]
I updated my visual studio from 17.9 to 17.10.1. Without changing anything to the dotnet code, the api won't start anymore and gives an exception in the program.cs file on the code rule:

var app = builder.Build();

Note: we are using Lightinject for depencency injection.

Callstack:

The problem is with z__ReadOnlySingleElementList which is embedded into your assembly at compile time. As far as I understand, it is used for the new style of array initialization like var nums = [5]. Seems you are using automatic type registration to their implemented interfaces which register z__ReadOnlySingleElementList<> to IEnumerable<>. Then the container tries to use z__ReadOnlySingleElementList<> in the cases where it needs to collect all implementations of an interface.

You can, for instance, filter out all the types that implement IEnumerable. Example using Autofac:

containerBuilder
    . RegisterAssemblyOpenGenericTypes(assemblies)
    . Where(x => !x.IsAssignableTo(typeof(IEnumerable)))
    . AsImplementedInterfaces()
    . AsSelf();
