C# ‘dynamic’ cannot access properties from anonymous types declared in another assembly

Question

Code below is working well as long as I have class ClassSameAssembly in same assembly as class Program. But when I move class ClassSameAssemb

Answer 1

ToExpando extension method (mentioned in Jon's answer) for the brave ones

public static class ExtensionMethods
{
    public static ExpandoObject ToExpando(this object obj)
    {
        IDictionary expando = new ExpandoObject();
        foreach (PropertyDescriptor propertyDescriptor in TypeDescriptor.GetProperties(obj))
        {
            var value = propertyDescriptor.GetValue(obj);
            expando.Add(propertyDescriptor.Name, value == null || new[]
            {
                typeof (Enum),
                typeof (String),
                typeof (Char),
                typeof (Guid),
                typeof (Boolean),
                typeof (Byte),
                typeof (Int16),
                typeof (Int32),
                typeof (Int64),
                typeof (Single),
                typeof (Double),
                typeof (Decimal),
                typeof (SByte),
                typeof (UInt16),
                typeof (UInt32),
                typeof (UInt64),
                typeof (DateTime),
                typeof (DateTimeOffset),
                typeof (TimeSpan),
            }.Any(oo => oo.IsInstanceOfType(value))
                ? value
                : value.ToExpando());
        }

        return (ExpandoObject)expando;
    }
}
