    I just migrated a solution from VS2010 to VS2012, and an exception occurs when I use the designer of VS2012 to create controls in my radForms: 
    System.Runtime.InteropServices.COMException (0x8004D745): A reference to the component 'Telerik.WinControls.UI' already exists in the project.

    The exception occurs only when creating RadControls by drag and dropping from the toolBox, when I add Groups to a RadRibbon by clicking on "Add new Group", it works fine.
    It also works fine when I add Windows Forms controls, the problem only occurs with Telerik Controls.

    I tried under VS2010 and there is no exception raised.

    I didn't get the problem when i used VS2010, so is there something special to do when migrating solutions from VS2010 to vs2012 ?

    ps : see the attached file to get a more complete stacktrace.

    As described in your corresponding support thread, I would recommend to ensure that the same version of our controls is loaded in the toolbox and referred in your project.

    To do this, please follow the steps bellow:
    1. Open the Configure Wizard (documentation: http://www.telerik.com/help/winforms/installation-deployment-and-distribution-vsx-creation-and-configuration-wizard.html) and check the version of the distribution used by the project
    2. Start the Toolbox Configurator (documentation: http://www.telerik.com/help/winforms/installation-deployment-and-distribution-vsx-toolbox-configurator.html) and ensure that the same version in loaded in the toolbox

    Kind regards,
    the Telerik team
    Q3'12 SP1 of RadControls for WinForms is out now. See what's new.
