Hello,
I have started learning .NET and I have a question: what are, in your
opinion, weak sides of .NET 2.0.
Thank you very much for your answers.

This is a very open question as alot of it is language specific.
As an example a static vs dynamic typing laguage. .NET has both and both
have their strengths and weaknesses.
It also brings up questions of what you are trying to compare it to? If you
are comparing it to C I would say that there are many spots where it will be
much slower.

VS 2005 is still Beta IMHO. .NET 2.0 foundation seems OK (still lacking all
the features I would like) but that is primarily due to the fact it is
really just wrapper code around the OS core. If you have mission critical
items, I would avoid using .NET.

Hello Michael,
..NET (any version) is not meant to be used for real-time processing. It's
not in it's design specs, and the documentation clearly states not to even
attempt it.

..NET library in particular? I would say:
* The drawing performance of WinForms applications, and general lack of
maturity of WinForms and GDI+.
* The steady and continuing pollution of System.* namespaces with
ugly Win32-isms (System.Diagnos tics.* in particular).
* The lack of some classical collections including trees etc. for
guaranteed logarithmic performance.
..NET runtime in particular? I would say:
* Debugging interop with native code can be confusing, because managed
code is at a different abstraction level (there's no easy way out of
this one, though.)
* Lack of flexibility in the underlying virtual machine model for
implementing dramatically different language features (e.g.
continuation passing style, poor tail-call performance, coroutines,
lightweight threading models).
* The existence of the .NET libraries requires languages to interoperate
well with its object model in order to leverage it. This in turn
forces languages with different object models to change their object
model, or be an awkward and strange member of the world of .NET, or
have two similar but subtly different object models.

All in all. .NET is great. Visual Studio is a tad ambitious and thus buggy.
My biggest gripe is lack of MI (Multiple Inheritance); I grew up with it and
miss it dearly. Enhance the CLR and C# to handle MI and you'd pretty much
have my dream environment.

Sure, but it's a map, not a set. If you look at the range of the
possibilities in the JDK, you'll see what I mean:
Interfaces:
* List
* Map
* Set
* SortedMap
* SortedSet
Classes:
* ArrayList
* HashMap
* HashSet
* TreeMap
* TreeSet
* PriorityQueue
* LinkedList
* LinkedHashMap
* LinkedHashSet
* EnumMap
* EnumSet
And some concurrent collections, many which use lock-free programming
techniques, so you don't have to (and they're hard to get right):
* ArrayBlockingQu eue
* LinkedBlockingQ ueue
* PriorityBlockin gQueue
* DelayQueue
* CopyOnWriteArra yList
* CopyOnWriteArra ySet
* ConcurrentHashM ap
* ConcurrentLinke dQueue
* SynchronousQueu e
The same level of choice for implementation of the same basic interfaces
doesn't exist in .NET at the moment.
This is not to say that JDK's collections are superior where comparable;
I don't think that's true. I far prefer .NET's List<T> to JDK's
ArrayList<T>.

Is it correct to say that strong/weak typing does not make a difference
if one does not use any pointers (or adress-taking operator)?
More concretely, I am thinking particularly of Python vs C++.
So, are there any examples (without pointers, references, or adress-taking),
which would have a different result in Python and in C++?
I would appreciate all insights or pointers to literature.
TIA,

Hi,
I've heard from groups that listeners to event handlers cause
references to be kept alive, if the targets are marked to stay alive. I
need to make sure that attaching events to objects will not cause them
to be kept open.
I created a test which has "target" listening to "source" for events.
After plugging source into target, I then let go of source. Since I'm
still holding onto target, if delegates were a strong reference, then

does C++ give a way to declare a specific symbol as a "weak symbol"?
In 'C', one can use #pragma directive.
Is this still a legal way in C++ ? Is there a (better?) alternative?

Are weak refs slower than strong refs? I've been considering making the
"parent" links in BeautifulSoup into weak refs, so the trees will release
immediately when they're no longer needed. In general, all links back
towards the root of a tree should be weak refs; this breaks the loops
that give reference counting trouble.

Hi all,
I've been considering that my objects should subscribe to an event via
a weak reference, however I've found several warnings that this
approach comes with concurrency considerations, like the fact that the
event handler method on the subscriber could be called and be
executing while the object is being garbage collected.
Not being super strong in the multithreaded department, I am having a
hard time coming up with other...
