Forum Tips and Valid Topics
Aaron Oneal [NCL]MSFTMonday, July 28, 2008 9:05 PMIs this the right forum?
This forum is monitored on a regular basis by the Network Class Library (NCL) team. It is dedicated to questions about the System.Net namespace and the System.Uri class. If your question falls into this category, then you have come to the right place.To ensure a timely response, we can only actively monitor questions that fall within the category above. Non-related questions will be locked or moved to the most appropriate forum.
General Forum Tips
Here are a few suggestions (in this order of relevance) that will help you to get the best answer to your question as quickly as possible:
-
Search for your question on the forums or in Visual Studio's help system first
-- it's likely someone may have already answered your question, and you
won't have to waste time waiting for it to be answered again
- Post in the correct forum
(see below) -- since the experts in various subject matters tend to
stick to the set of forums that focus on those topics, a question about
the C# yield keyword posted in the Common Language Runtime forum will
likely take a lot longer to be answered than the same question in the
C# Language forum.
- Give details about your problem
-- rather than "When I call Process.Start I get an exception, please
help", provide the exception type, message, and call stack. Many times
it helps if you attach a snippet of the network trace/sniff of the
error that shows the error. For getting network sniffs use Network
Monitor and for network traces use the built in System.Net tracing
according to this blog.
If possible, provide a succinct code snippet that demonstrates the problem. This lets us reproduce the problem on our end and allows us to come up with an answer where just a general question may not have had enough details. Having this information means we can answer your question more quickly, without having to ask you for these details and wait for your response. If you have a big code sample please trim it down to the relevant parts that will help us understand the problem better. - Try to pinpoint the location of your error –
This will help us get to the root of the issue quickly. Saying
something like “My application cannot read from server” is less likely
to find a quick solution as compared to “My application gets a 505 not
found even though file is present since the trace shows that
FtpWebRequest does not handle a 505 error for an xyz command”
- Make sure your title summarizes the specific problem you have
-- since we try to answer the maximum number of questions we can with
our time, we often skim through question subjects to quickly find the
ones that we know the answers to. A question with a title of "Urgent!
Help needed!" is not as likely to get answered as a question with a
title of "How to define a sealed class using CodeDOM". A more
specific, detailed title is far more likely to get a response than
a general one.
- Once
you've received a correct answer to your question, either from a
Microsoft employee, an MVP, or the community in general, please mark
the post as answered.
You can do this with the "Mark as correct answer" button that appears
on the entry containing your answer. This step is important, since it
lets the Visual Studio search engine know that there is an answer in
that thread for others who may also have your problem. It also lets
people scanning the forums know that they can find an answer to that
question by reading the thread.
- Report bugs through Microsoft Connect, instead of on the forums
-- this site allows us to see the bugs in our bug
tracking database and get them assigned to the correct person. It also
allows you to follow the problem through to its resolution, and is a
much better way for us to handle issues you find than a bug report
posted on the forums.
- Use the report button -- as moderators we try to keep spam and inflammatory comments out of the forums. However if you do catch something that we missed, don't hesitate to use the report button so that we can keep the forums on-topic and a friendly place to go for help with your .NET questions!
