In general when upgrading to a newer version of our controls it is not very likely that you get various errors. However, it is possible that there are cases when there are issues related to the upgrading/installation process. By looking at the error that you describe it seems that the project/application that you are attempting to run can not find reference to the Telerik.Web.UI.Skins.dll
assembly file where the Metro
skin is located. There are two reasons for the exception to be thrown - there are either no references set to the upgraded assembly files or the references are still the old ones pointing to the GAC
. To resolve the exception you can try using the following approach - place all of the assembly files (Telerik.Web.UI.dll
) in the local bin folder and update the references as demonstrated in this video.
