How come a non-const reference cannot bind to a temporary object?
... what you are doing and you are explicit about it (like, using reinterpret_cast). But if you bind a temporary to a non-const reference, you can keep passing it around "forever" just to have your manipulation of the object disappear, because somewhere along the way you completely forgot this was a te...
How to retrieve the LoaderException property?
...ng it as one type, why create another variable with the same type and do a cast? This should suffice: catch (ReflectionTypeLoadException ex) { var loaderExceptions = ex.LoaderExceptions; }.

Why is (object)0 == (object)0 different from ((object)0).Equals((object)0)?
...
When you cast the int value 0 (or any other value type) to object, the value is boxed. Each cast to object produces a different box (i.e. a different object instance). The == operator for the object type performs a reference compariso...
Count the items from a IEnumerable without iterating?

result++;
}
return result;
So it tries to cast to ICollection<T>, which has a Count property, and uses that if possible. Otherwise it iterates.
