Or you can simply add this lines to your web config

<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35"/>
<bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31bf3856ad364e35"/>
<bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
</dependentAssembly>
</assemblyBinding>
</runtime>

This is going to save me a lot of time when we move to the 3.5 from 2.0 .net in the coming months.

Thanks Joe!

Hi Joe:
Thanks for your great videos on asp.net. and the blogs.
I tried to upgrade a 2.0 project, where I had reference of earlier version of toolkit, now I copied the new toolkit for 3.5 as you have said. Now, when I try to build the project I get the following Error:

The type 'System.Web.UI.ScriptManager' exists in both 'c:\Windows\assembly\GAC_MSIL\System.Web.Extensions\1.0.61025.0__31bf3856ad364e35\System.Web.Extensions.dll' and 'c:\Windows\assembly\GAC_MSIL\System.Web.Extensions\3.5.0.0__31bf3856ad364e35\System.Web.Extensions.dll'

most of the solution in google to go back to earlier version, which I dont want to do. Do you have any idea, how can I get rid of this issue ?
Thanks in advance.

Joe:
Thanks a lot for your reply. I had a older version of the System.Web.Extension.dll in the bin directory of my project. I deleted it, and everything build successfully.
Thanks again for your hints.

Joe, Its cool to see someone using the BlogEngine.Net

I got a question for you. I did what you said and have been stuck on this problem for about 5 or six hours. When I remove the references as you said, I get the following error.

A ScriptManager is required on the page to use ASP.NET AJAX Script Components.

Basically it means from what I think, it can't find the script manager, but I got one up front and on the page. Then when I switch back from your changes, I get the error that brought me to this page from Google.

"'ScriptManager' is ambiguous in the namespace 'System.Web.UI'." 3.5.0.0

Wanna help me out?

Okay,

So I just used what Petr Šnobelt posted in the first comment here and it all worked perfectly! Thank you Peter.

The other thing that can cause this is leaving the text xmlns="schemas.microsoft.com/.NetConfiguration/v2.0" in the <configuration> section of the config file - which seems to do something with the namespaces and thereby causes the ambiguity with the script manager no matter what you do with components and references

:~( I have been working on this for 2 days now and nothing is working. I remove the reference in fact I remove both reference and I have added other components and both references are right back in the properties. I have tried to add Petr’s code but that errors out on me too. I don’t see a reference in the bin folder to remove it there either. This is my first exposure to AJAX and I really could use any help or suggestion. Is there any way I can uninstall the older version?
