Hi all !

I had : SP1 causing "Adding reference to System.Web.dll ..."

I tried all solutions founded in this forum but with no result!

But finally it works well.

In my case, I use Visual Studio with SP1 and AjaxToolkit.

When I try to open the project website it freez trying to add System.Web.dll

The solution:

I founded that I had a bad path in AjaxControlToolkit.dll properties.

(I changed my project from a pc to an other and missed to change the update path of the source dll.)

With the rigth path all works fine.

Hope that helps !!!

Well, I tried all these suggestions but no luck. This is happening on a new server after setting up a new server, and then publishing existing pages to new server. Also, this only happens when the page has a Master page applied. I created a new page without a master page, and it jumps to design view instantly. I use VWD 2005 on XP pro in a network. The site is developed on a separate dev server. On our old server, I don't have this problem, but a coworker does.

Any new ideas?

Thanks,
SMc

The other alternative is copy the file locally and load it into the GAC manually.

What you see is a different issue. Web sites on a network share is not a supported scenario because network locations are not considered trusted in .NET and hence assemblies won't load from network share. You have to add network location to trusted zones using .NET CasPol utlity.

My solution was:

1. open the Microsoft .NET Framework 2.0 Configuration under Administrative Tools

2. under Runtime Security Policy section, click Adjust Zone Security link

3. Increase the Local Intranet zone to full trust

4. open the Internet Options section of the Control Panel and add the network location to the Local Intranet section on the Security tab

I uninstalled VS2005 SP1 and everything works great!

The answer to this for me was related to permissions in the c:\windows\microsoft.net\framework folder. As I was using impersonation in my web.config file I added modify permision to the aforementioned folder for the account I was impersonating. I'm sure one could be more specific about which sub-folder needs these permissions but I was in a hurry.

It worked immediately.

I am wondering if something else might be involved. The PC that my co-worker is using and getting "Adding reference to System.Web.dll..." error message, has the following (that I can think of):

Windows XP Pro with SP2
VB6
Crystal Reports XI Release 2
Visual Studio 2003
Visual Studio 2005 with SP1
.NET Frameworks 1.x, 2.0 and 3.0
SQL Server Client Tools for SQL 2005
Microsoft AJAX 1.0 installed (it never had Altas on it, to be best of my knowledge)

It does not have IIS enabled.

I'm wondering if not having IIS installed might be a part of the cause of the problem? If IIS were installed then you could select which .NET Framework the web app would use, but she cannot do this since there is no Internet Information Services applet in the Control Panel. I am thinking that perhaps Cassini is just selecting at random the .NET Framework that it wants to associate with the web app. Does this make some sense?

prbabu:

Basically, if Visual Studio has been referencing an assembly/DLL which no more exists in the system(one reason is while uninstalling someother application), this issue can raise.

Solution: Remove the extinct reference from the solution and things should turn fine.

We've had a new developer start this week and she's getting this error messaage. (None of us have ever encountered this error.) So, I'd reading this thread with a lot of interest.

One thing I am wondering about, could it be the case that this error message about "Adding reference to System.Web.DLL" and "Adding reference to System.Web.Extensions.dll" is somewhat misleading? Might there be some other assembly which is really missing, but the VS IDE is reporting only on System.Web and System.Web.Extensions?

I've tried this as well as many of the other options listed here to no avail. I'm running XP SP2, along with VS2005 SP1. I do not have AJAX installed. I have repaired 2.0 Framework. I've deleted the web.config, and re-opened VS2005, and it just worked on re-creating the web.config file, with the same message in the status bar. I am using Visual Source Safe. I just recently moved to a new pc, and am having these issues. Any web project in VS2003 works great, just VS2005 is having issues. Any help here would be greatly appreciated, as I really need to work on a several web projects in VS2005.

I had the message adding reference to 'System.Web.dll"... shows in the status bar when I switch to the design view.

What I did to have it solved for my temporary solution. I deleted the web.config file and then go ahead to open the project. After it opened successfully restore the web.config back to the project. Now, when I am trying to switch the design view back and forward, the Add reference to ‘System.Web.dll’ is not longer showing in the status bar and running perfect.

+1 more... Removing the web.extensions assembly reference from the web.config file worked like a champ. Thanks to all who've contributed.

Thanks Mikhail,

That did help. I still got the 'adding reference...' message in the status bar, but only briefly. I also manually added a reference to system.web.dll and system.web.extensions.dll.
The main thing is now all my intellisense works again!

Thanks for your help.
Tim

While it is true as Mikhail's said; however, I have never had any problems with network share folder under Windows XP Pro. I have all kinds of problems under then sun when using VS2005 and Vista together.

I'm having the same problem, and none of the solutions suggested are helping .. i've wasted alot of time trying to get this resolved!!

The problem is happening only when loading websites from a network drive. Copy the whole website folder to the local disk and it runs fine. When trying work on it directly on our dev server the problem is there. This is infuriating because i don't want to have to copy my files over to the server all the time.

Furthermore, when i get the message in the status bar 'adding reference to system.web.dll' there is a alot of cyclic network traffic.

I have this problem after installing a fresh copy of VS 2005, then installing SP1, then installing the Vista update (kb932232). Would be interested to know if people on XP are experincing this, or is it just Vista?

Can anyone help with this? like i said, works fine when working on local websites, but unbearable when trying to work off our dev server. I NEED to work off our dev server. Dev server has AJAX and .NET 2.0.
Could this be caused by installing VS 2008 beta 2 on my laptop? maybe .net 3.0/3.5 are causing some problems?

Any help appreciated.
