While we are working on resolving the issues you contacted us about in the ticket, could you share more details on your upgrade experience? You mentioned that there is no upgrade wizard in your environment, have you installed the Telerik Visual Studio Extensions
and are having troubles with the upgrade wizard or is it that you simply have not installed the extensions?
Overall, the upgrade wizard is the fastest way to change the version of Telerik UI for WPF your project uses. If you do not want to use it, your only other options is to change the binaries manually.
Since the assemblies in the suite depend on one another, your project needs to contain assemblies from a single version and the most common causes fur such errors are either a reference from another version is still added to the project or Visual Studio has cached files. In the latter case, a simple Clean
of the project usually resolves those. Deleting the bin
folders that are created by Visual Studio might also help.
