IList <something> and AutoFixture Constructor Parameter

Question

Using autofixture , I am trying to build an anonymous instance Project:

 _f=new Fixture().Customize(new AutoMoqCustomization());
 _p=_f.CreateAnonymous<Project>();

It fails, the constructor is called Project IList<Partner>

public Project(/*.....*/,IList<Partner> partners){
  Guard.AgainstEmpty(partners);
}

Stack tracing doesn't make sense (at least for me). Just some reflection of the poison:

failed: System.Reflection.TargetInvocationException: An exception was thrown by the target of the call.
---- System.ArgumentException: value is not in the expected range.
    in System.RuntimeMethodHandle._InvokeConstructor (IRuntimeMethodInfo method, Object [] args, SignatureStruct & signature, RuntimeType declaringType)

So, how do you make sure autoFixture allows an anonymous collection of partners to create it?

IList<Partners>. Priority. Priority Measure, Measure IList<Indicator> Guard.AgainstEmpty(indicators) .

, :

fixture.CreateAnonymous<Foo>(); //kaboom!
public class Foo{
  public Foo(IList<Bar> bars){
    Guard.AgainstEmpty(bars); //just checks count for ienumerable & throws if 0
    Bars=bars;
  }
  public IList<Bar> Bars {get;private set;} //should be readonly collection...
}

public class Fizz{
  public Fizz(Foo foo){
    Foo=foo;
  }
  public Foo{get;private set;}
}

public class Bar{}

Guard.AgainstEmpty. - - , AutoFixture foos?

var indicators=_f.CreateMany<Indicator>();
_f.Register<IList<Indicator>>(()=>indicators.ToList());

  var regionName=_f.CreateAnonymous<string>();
  _f.Register<string,Country,bool,Region>((name,country,call)=>
    new Region(regionName,_f.CreateAnonymous<Country>(),true));
  _c.Set(x=>x.Regions,_f.CreateMany<Region>().ToList());
  _f.Register<IList<ManagementBoardEntry>>(()=>
    _f.CreateMany<ManagementBoardEntry>().ToList());
  _f.Register<IList<FinancialInfoEntry>>(()=>
    _f.CreateMany<FinancialInfoEntry>().ToList());
  _f.Register<IList<Partner>>(()=>_f.CreateMany<Partner>().ToList());
