    My team inherited a rather poorly written application which included the use of Telerik controls.  Any view that has a RadGridView control throws the exception as we are locked into the 3.5 framework for now.

    I downloaded the demo but the library isn't there as well.

    Where can I download the library?

    Hello Michael,

    This assembly is not part of RadControls for WPF,  I would suggest to post this question in MSDN forums or StackOverflow.

    Thank you for the understanding.

    Obviously you do not know the product you are supporting:

    The System.ComponentModel.Composition.dll of version 2009.7.8 is released with the WPF 3.5 version of the controls, as in .NET framework 3.5 there is no System.ComponentModel.Composition assembly. As RadRichTextBox uses MEF for loading the pop-ups that it uses and format providers, we had to implement an equivalent for WPF 3.5.
    If your project targets .NET framework 4.0, you should be using the dlls that have been built for WPF 4 and adding a reference to this Composition assembly would not be required. There are separate zips with hotfix dlls and installers for WPF 3.5 and WPF 4, which you can download from your account.

    Now -- where do I get the dll from so that I can see the controls in design mode?

    Hi Michael,

    I am sorry for my mistake.

    The latest version of RadControls for WPF for .Net 3.5 we released was Q2 2012 SP2 ( 2012.2.0912 ), so the needed assembly is included there.
    I have attached it to to this thread, so you can download it directly.

    Hope this helps.

    Thanks for sending me the zip file.  Much better than downloading the demo (if it is out there) and getting the marketing guys drooling all over me thinking I'm another sale.
