Fixed locally by changing
if (
propType.IsGenericType &&
(
propType.GetGenericTypeDefinition() == typeof(Nullable<>)
||
propType.GetGenericTypeDefinition() == typeof(List<>)
)
)
to
if (
propType.IsGenericType &&
(
propType.GetGenericTypeDefinition() == typeof(Nullable<>)
||
propType.GetGenericTypeDefinition() == typeof(List<>)
||
propType.GetGenericTypeDefinition() == typeof(IList<>)
)
)
