Question

ASP.NET 3.5 Error moving app Could Not Load File or Assembly System Web Extensions 3.60

Asked by: ChiBella

I copied a web app from one laptop to another (vs 2008 .net 3.5) but getting error

Could not load file or assembly 'System.Web.Extensions, Version=3.6.0.0, Culture=neutral, PublicKey=xxxxxxx or one of its dependencies. The system cannot find the file specified.

The AjaxControlToolkit.dll is in the bin and referenced in the app so what else am I missing here?

Hello,
Get the following dlls from
C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\[Version of Framework]

AJAXExtensionsToolbox.dll
System.Web.Extensions.dll
System.Web.Extensions.Design.dll

Once you have done that make sure you have the following files in your bin.

They came with the new install of AJAX.

Also we have to make sure that in our web.config under assemblies the PublicKeyToken portion is all Caps!

Please le me know, if you have any question.

Good Luck

Thanks
Ganesh

I am on VS 2008, .NET 3.5 not 2.0.

by: ChiBellaPosted on 2008-08-08 at 09:54:19ID: 22191593

I ran the AjaxToolKit on the new pc and referenced the AjaxToolKit.dll in the bin of the app on the new PC, essentially, like installing it...but I still have this issue.

by: ChiBellaPosted on 2008-08-08 at 10:06:26ID: 22191680

Also, I do not have the directory you specified...

I looked at the original install and it does not contain as a reference system.web.extensions 3.6, it contains a reference to 3.5...so now I am totally confused.

The web.config contains this
<sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=3.6.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

and it works fine within the original but not within the new install on a separate machine....even though the same dll's are referenced.

What version is 3.6?

by: ChiBellaPosted on 2008-08-08 at 10:22:22ID: 22191810

I took out the 3.6 line in the web.config...then I made sure the system.web.extensions dll existed and had a reference...but still same issue, only now for the 3.5 version.

Can anyone tell me what is going on here?

by: gdupadhyayPosted on 2008-08-08 at 10:26:56ID: 22191840

Avtually i faced same problems when i moved from 1.1 to 2.0. I did same thing and problem was resolved.

Is all 3 dll files is in BIN folder? If not, please put it.

Please follow the same path. You just need to modify the version from 2.0 to 3.5.

by: gdupadhyayPosted on 2008-08-08 at 10:35:15ID: 22191925

You are facing version related problems. If you copied your all application from your one laptop to another one, how the web.config file changed? Make sure, installed software configuration is same on both system.

by: ChiBellaPosted on 2008-08-08 at 10:40:39ID: 22191978

All files are there...it is the 3.6 that is missing but I don't know what 3.6 is? Where is the install for 3.6? Where is it physically located?

Well that didn't help.

I found the 3.6 versions of system.web.extensions and moved them to the other machine and was able to compile, but at runtime now I get this error:

by: ChiBellaPosted on 2008-08-08 at 12:05:45ID: 22192729

I checked the versions of .net 3.5 and the original, one that works...is 3.5 while the new install that does not work is 3.5 sp1, could this be what is wrong?

by: gdupadhyayPosted on 2008-08-08 at 12:25:17ID: 22192884

You install SP1. That's why its become 3.6 from 3.5. Your original was with 3.5 and now it is 3.6. So it is giving problems.

Install SP1 on your 1st machine, then try to install on other one.

by: ChiBellaPosted on 2008-08-08 at 12:29:58ID: 22192911

No....it is the exact opposite.

The one that works is not sp1, the one that fails is sp1!

by: gdupadhyayPosted on 2008-08-08 at 13:02:28ID: 22193186

I am sorry, If you not understand my previous post.

Install SP1 on your 1st system (where it works). Compile and run the project. Then install on 2nd system (where it fails).

The reason is: SP1 updated some component. So we required same version of DLL files on each and every system.

Before doing this: Could you please send to us the web.config file of the system, where you are getting the error and version of all 3 components.

I just want to look into this.

by: ChiBellaPosted on 2008-08-08 at 13:06:30ID: 22193213

I am not going to install sp1 on the machine it is working on. That is my working system and my baseline...why would I do that?

The goal is to get the second machine at par with my baseline.

by: ChiBellaPosted on 2008-08-08 at 13:10:17ID: 22193253

I don't want a beta version of an sp when I deploy.

by: gdupadhyayPosted on 2008-08-08 at 13:34:59ID: 22193433

Ok, send me your web.config file and current version of all component from your 2nd machine, where you are getting error.

by: ChiBellaPosted on 2008-08-08 at 13:36:23ID: 22193442

I will after I try one last thing.. I am going to remove visual studio on the second machine and install the RTM version.

by: gdupadhyayPosted on 2008-08-08 at 13:48:07ID: 22193523

Ok, The problem related to the version of the component. I am sure, after installation fresh version of Visual Studio on 2nd machine, your problems will solved. Because on both machine you will have same version of component.

GOOD LUCK

by: ChiBellaPosted on 2008-08-08 at 17:01:54ID: 22194462

Well, this didn't fix my problem.

I uninstalled VS 2008 sp 1 and installed the rtm but still get this error:

Ok, it is working now.

Not sure exactly what was wrong but I had to do two things to make it work.

1). Install the correct versions of vs 2008 (no sp1), and .net extensions ctp (system.web.extension 3.6.0.0)

2). Had to re-install the AjaxToolKit for 3.5. I could not simply copy the dll from one machine to another, I had to download it and compile it on the new machine.
