When I run my asp.net app I get the error
The type ‘System.Web.UI.ScriptManager’ is ambiguous:
I am having the same problem this person is having http://forums.asp.net/t/1313257.aspx , when I change the 1.0.61025.0 to 3.5 and re-compile It resets it to 1.0.61025.0
what I can I do to resolve this. I've been trying to get my app running for hours now.
Thanks

I see 2 system.web.extensions in the GAC. I tried to remove with gacutil.exe /u system.web.ext
ensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
Microsoft (R) .NET Global Assembly Cache Utility. Version 2.0.50727.42

Unknown option: Version=1.0.61025.0
what am I doing wrong.
Edit ~ MY SOLUTION
I went to "Add Remove Programs" and un-installed the Ajax Web Extensions 2.0 version 1.0.61025.0
Best Answer
It looks like you are (perhaps indirectly) referencing the old System.Web.Extensions DLL. Check your config file and search your application for "System.Web.Extensions". Also make sure the old version is not in your bin folder (and does not get copied there).
Make sure you are not using any other libraries that use the old System.Web.Extensions DLL, ie the AJAX Toolit 1.0.x.
