To fix one problem, I upgraded SF 3.7 from SP2 to SP4. Now I'm getting the following error (and 110 others, for each Telerik web control) when I build the site on my development machine.:
Error 3 The type 'Telerik.Web.UI.RadWindow' exists in both
2008\WebSites\SitefinityDev\Sitefinity\UserControls\HR\eSignInBox.ascx.cs 18 4 C:\...\SitefinityDev\<
I followed your upgrade instructions
, except for step 10, which I don't think apply. The only user controls in this web site that use Telerik controls are in the site's project, under Sitefinity/UserControls, which seems to me that they would use the same reference as the site. If this step does apply, then I don't understand how to apply the instructions.
I've gone into the site's properties and removed the reference to the version in the GAC (the reference to the correct version in the site's /bin folder is still there), but it comes back on its own.
It looks like I need to replace the manifest in the GAC, but where do I find the manifest for Telerik.Web.UI?
