为什么没有捕获RuntimeBinderException？

Question

我理解为什么它会被抛出，但为什么当我有一个catch块时它仍然未处理？有关详细信息，请参阅附图。

try
{
    // Exception is thrown at the following line as not all items have Id property
    addedLabours = currentLabours.Where(c => !previousLabours.Select(p => (Guid)p.Id).Contains((Guid)c.Id)); 
}
catch (RuntimeBinderException) 
{
    addedLabours = currentLabours;
}
