with AJAX RC, how to handle system.web.UI namespace conflict? thanks

I add those under namespaces in web.config before when I use beta 2

<add namespace="system.web.UI"/>

<add namespace="microsoft.web.UI"/>

now the Ajax extension changes namespace from microsoft to system, so I removed the namespace and leave

<add namespace="system.web.UI"/>

but I still get error, how to handle this?

thanks

What error are you receiving?
Get the web.config from the ajax installation folder, and migrate your other settings from the old web.config. It's a pain, but that way I've never had any web.config error because of moving from beta1 to beta2 and so on. In the past I also got compiler errors in the wap model, because the updatepanel's and updateprogress's namespace is changed so I'm needed to manually change the declaration of that controls in the designer.cs files.

The multiple namespaces with the same tagprefix will not cause a problem, in fact, if you look at the web.config inside of the c:\Windows\Microsoft.NET\Framework\v2.0.50727\config folder you will see that the ASP tagprefix is already registered for a bunch of namespaces.

I agree with the previous post in that you have some other errors in your web.config.

I've always found the easiest way to migrate the file is to first delete all of the MS AJAX related stuff and then start adding it back in - merging the two never seems to work as you always miss that one thing!

Yes it shouldn't be a problem. I only have codebehind (designer.cs) problem in the past when the UpdatePanel is moved from Microsoft.Web.Preview.UI to Microsoft.Wen.UI, that needs manual correction.

hello.

i still didn't get the error...what is it?

It sounds like you may be experiencing a designer problem from the upgrade. I suggest you try deleting all of the files in:

C:\documents and settings\[username]\Application Data\Microsoft\VisualStudio\8.0\ReflectedSchemas
