A FAQ is a list of Frequently Answered Questions;
This is a guide to using this newsgroup intelligently in order to find answers to your
ASP.NET questions.

The kind of answer you get to your questions depends on the way
you ask the questions as well as on the difficulty of writing the answer.

This FAQ will show you how to ask questions in a way that is likely to get you the answer
you want to get : the right answer.

You have to do your part, too, if this is going to work out in such a way
that you *learn* what you need to learn, instead of getting ready-made answers
which you will promptly forget and need to ask for them again.

With that in mind, the first FAQ recommendation is that you use search engines
to find out if the question you intend to ask has been already answered in newsgroups.

Use resources like :

Google Groups Advanced Search ( )
MSN Search ( )

to search for the text of the problem which is stumping you,
and save everybody the waste of time that asking a FAQ entails.

Remember : thousands of programmers will read your post. Be considerate of their time.

1. General ASP.NET Questions

1.1 What is ASP.NET?

ASP.NET is a technology for creating dynamic Web pages which uses the .Net Framework.

You can author applications in any .NET compatible language, including Visual Basic .NET,
C#, and JScript .NET, and many others listed at .

1.2 Where can I get ASP.NET?

You can get ASP.NET by installing the Microsoft .NET Framework on a computer which has IIS
The .NET Framework is available in either a redistributable or SDK format.

ASP.NET 2.0, currently in Beta, will be released the first week in November, 2005.

1.3 I've installed the .NET Framework, but ASP.NET doesn't seem to work.
What can I do to fix it?

You must install IIS before you install the .NET Framework.

If you install IIS after you install the .NET Framework,
you must then register the ASP.NET extensions with IIS.

You can do this by running the aspnet_regiis executable from:
%windows root directory%\Microsoft.NET\Framework\%version of the .NET
Framework%\aspnet_regiis -i

Where %windows root directory% is the directory Windows is installed to
(normally c:\windows or c:\winnt) and %version of the .NET Framework%
is the version of the .NET Framework you have installed.

The directory for .NET 1.0 is v1.0.3705 ; for 1.1 it's v1.1.4322 and for Beta 2, it's

It's always a good idea to try to find the answer to your question by reading the
Yes, Read The Manual! The ASP.NET Quickstarts have many answers and samples.

You can install a local copy of the QuickStarts by installing the ASP.NET SDK.

The ASP.NET 1.1 SDK is available at :

The ASP.NET 2.0 SDK comes with the VS.NET Beta :

If you can't install local copies of the ASP.NET QuickStart,

the ASP.NET 1.1 QuickStart is available online at :

The ASP.NET 1.1 Starter Kits are available at :

The ASP.NET 2.0 QuickStart is available online at :

The ASP.NET Beta 2 Starter Kits are available at :

Always try to find an answer by experimenting with the code.
The .NET Framework Class Browser is of great assistance to help you do this.

The .NET Framework 1.1 Class Browser is available at :
and also at :

The .NET Framework 2.0 Class Browser is available at :

MSDN has all the ASP.NET documentation and Knowledge Base articles online.

2. Newsgroup Questions

2.1 What subjects are appropriate in this newsgroup?

Any subject which relates to programming, installing or configuring ASP.NET.
Please don't post questions unrelated to ASP.NET.

ASP.NET is not the same as ASP. If you have questions relating to "Classic ASP",
post them in the ASP newsgroups, e.g. microsoft.public.inetserver.asp.general.

We encourage the posting of links to free ASP.NET controls/assemblies you have developed,
but request that commercial product availabilities be sent to :


Otherwise, your post will be deleted as SPAM.

2.2 How to write your post

a. Make the "Subject" a short, relevant summary of your problem

b. Make sure you describe your problem accurately.
Please post the exact code which is failing/generating your error.
That will help others find the solution to your problem.

c. Deal with one problem at a time.
If you have more than one problem, post it separately.

d. Make sure you include the version of ASP.NET and the
operating system you are using. This *really* helps others help you!

If the problem is a browser-related problem, include the relevant
browser identity and operating system information.

e. If you are getting an error message, include the error number and its text.

f. Tell us what you have already tried to do to solve the problem.

2.3 How not to write your post

a. Avoid cross-posting, unless your problem applies to more than one newsgroup.

b. Never post identical messages with different subjects.
This is a sure way to get your posts ignored.

c. Don't post your message in ALL CAPITALS. It's very hard to read.
This is another sure way to get your posts ignored.

d. Don't use unclear subject lines which don't summarize a problem, like these:

Need help please.
Any experts here?

This is yet another sure way to get your posts ignored.

e. Don't ask for an email reply. The basis for peer-to-peer help newsgroups
like this one is for *everybody* to be helped by the answers provided.

f. Don't flame anyone, period. Nobody needs that in technical newsgroups.
If something, or someone, irks you, ignore the post.

Please treat all participants with respect, valuing divergent views and contrary
Be polite. Share your perspectives to question ideas and stimulate interesting

g. The ASP.NET newsgroups, like all Microsoft public ng's, are unmoderated.

From time to time, there will be totally off-topic posts from trolls, spammers,
pornographers, etc. Please don't reply to these posts, as it's a waste of time.

Instead, killfile the poster if the post bothers you.

Microsoft has an anti-spam program in effect, and spam messages
are eliminated by a community program, but it's difficult to detect
some SPAM messages. Have patience and don't reply to any SPAM message.

We will get to it, and delete it.

2.4 Dealing with replies to your post

a. Trim unnecessary text from the replies to your posts, leaving just enough to
get the context of the reply and the original problem. This is greatly
appreciated by the people who are trying to help you, since it saves them time.

b. Analyze the suggestion you were given, and test to see whether it solves the problem.

c. If the problem isn't solved by the suggestion, explain why in a follow-up reply.

2.5 After you get your answer...

a. Confirm whether the proposed solution worked or not.

b. Thank the poster who gave you the answer to your question.

For people who spend their free time, unpaid, helping others in
peer-to-peer newsgroups, there's nothing better than to get a "Thank you".

Your "Thank you" is also helpful to others reading about your problem
because they see that the solution sent to you *did* work.

Mr Newbie

Just out of interest, you posted this comprehensive FAQ for the group, but
it left me wondering if you are someone in authority ( Microsoft Employee
etc ) or have you just thought you would post this for general consumption.
Also, where did this FAQ come from ?

Regards - Mr Newbie.

Juan T. Llibre

it left me wondering if you are someone in authority (Microsoft Employee

My only "authority" is having dealt with ASP.NET since pre-beta,
and with ASP since pre-beta, since 1997.

I have also co-authored a few books on the subjects : T. Llibre

That might confer me some "authority", too. ;-)

MVPs cannot be Microsoft employees, btw.

you just thought you would post this for general consumption.

Yes I did, primarily as a guide for ASP.NET newbies.
The online version is at :

Also, where did this FAQ come from ?

I wrote most of it.

A couple of friendly guys who frequent this newsgroup reviewed it
and made some very much on-target suggestions for improvement.

I took their advice and corrected what concerned them.

If you have any suggestions/corrections/additions for the FAQ, please email me.
The email address is both on the FAQ posted and at the website.

btw, the Q & A portion of the FAQ will be ready shortly.
There's already some 200 questions and answers in it.

I will post the URL here as soon as it's ready.

best regards,



Alan Silver

Was not a knock, just a question is all !

If you look back through the recent postings here, you'll see that the
main input for the FAQ came from a recognised expert in the field, with
peer review and suggestions from other people here.

The fact is that there are enough knowledgeable people here who have
looked at it, that if there were any mistakes, they would have been
spotted and fixed by now.

Hope that answers your question ;-)
