ComplexTypes broken on ASP.NET Core in RC7

[robertmclaws]

Issue

Given a simple unbound function on an EF API:

/// <summary>
/// 
/// </summary>
/// <returns></returns>
[UnboundOperation(OperationType = OperationType.Function)]
public SaleStatus CanUserDoSomething()
{
    return new();
}

Requests to said method throw an exception.

Exception Thrown:

System.InvalidOperationException: The given model does not contain the type 'Microsoft.Restier.AspNetCore.ComplexResult'.
