Since
Q3 2011, all existing skins, except
Default, are moved to a separate skins assembly (
Telerik.Web.UI.Skins.dll).
By doing so, we were able to reduce few megabytes off the main assembly and
transfer that load to the skins assembly. And though 6 megabytes might seem
modest for some, it's some
40% reduction in terms of the file size:
Separate Skin Assembly in RadControls for ASP.NET AJAX with Q3'11.
As
it was mentioned four months
ago, all embedded skins (except the
Default one, which will remain
plugged in the
Telerik.Web.UI.dll) will be shifted to the
Telerik.Web.UI.Skins.dll and to utilize any embedded skin other than the
Default skin, you will have to have a valid reference to the new AJAX
skins dll in your project.
If a different from the
Default skin is set and the
Telerik.Web.UI.Skins.dll is not present in the /Bin folder, the following server error will appear on the page:
Telerik.Web.UI.[Telerik Control] with ID='[Telerik Control ID]' was unable to find embedded skin with name '[Skin Name]'. Please, make sure that you spelled the skin name correctly, or if you want to use a custom skin, set EnableEmbeddedSkins=false.

Note that you should restart Visual Studio after adding a reference to the
Telerik.Web.UI.Skins.dll.
If you use the
Telerik WebUI VSExtensions upgrade wizard to update your projects, upgrade the tool to version 2011.3.1125.0 or later in the Extensions Manager of Visual Studio. This will ensure that the
Telerik.Web.UI.Skins.dll assembly will be copied automatically to the
/bin folder by the upgrade wizard.
