First I want to excuse for the misleading information that I have provided. We haven't removed the integration with the 'Add reference' dialog. If you don't see the Telerik assemblies in the 'Add reference' dialog then I suggest you to run installation repair using the msi installation package.
Doug, as far as I understand you have tried to upgrade using the latest hotfix zip package but something has gone wrong. You don't see the Q2 version in the Program Files because you didn't use the msi installation package. I encourage you to download and use the Q2 msi installation package. You are eligible to download it since it is covered by your subscription. You can find the file under your Telerik account in the 'Manage products'
section. If you need any further assistance I suggest you to open a formal support ticket.
Mat, currently we don't have automatic Toolbox integration for RadControls for Windows Phone because it is not supported by Visual Studio yet. We will try to provide you help regarding your issue in the ticket that you have opened.
