Hi
I am doing a test upgrade on my local machine. I have a 4.9.5 installation that I want to upgrade to 5.5.
I have done the following:
1. Renamed web.config to web.config.august2010.resources
2. extracted 5.5 Upgrade package to my website root
3. renamed release.config to web.config, and set connectionstring values accordingly, as well as replaced the machinekey settings.
4. Tried to navigate to the site, and got this error :
Configuration error - could not load file and the cause was this line in the web.config:
<add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule, Telerik.Web.UI" />
5. Realised that the site was running on .Net 2 framework, and not .net3.5
6. Changed IIS settings to latest .Net framework (4 - this should have 3.5 included no?)
7. Tried again to navigate to the site, and now get this error:
Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: CS1703: An assembly with the same identity 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' has already been imported. Try removing one of the duplicate references.

I can't seem to fix this - if I comment out the following line
<add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
Then I get the same error, just that Version=3.5.0.0 is changed to 4.0.0.0
Anyone know what could be causing this error?
