    I've been working with a trial version for a while which is I think a release older than the current. Today I purchased the full version and I've been having trouble getting it to work.

    I get the following crash t if I set the Linker Behavior to "Don't Link":

    Can't find custom attr constructor image: /Users/xxxx/Library/Developer/CoreSimulator/Devices/xxx/data/Containers/Bundle/Application/xxx/ mtoken: 0x0a000079

    Unhandled loader error: 7, (null) Xamarin.iOS, Version=, Culture=neutral, PublicKeyToken=84e04ff9cfb79065 ObjCRuntime.UserDelegateTypeAttribute
    error: * Assertion: should not be reached at ../../../../../mono/mono/metadata/loader.c:299
    critical: Stacktrace:


    If I set the Linker Behavior to: Link Framework SDKs only, I get a compiler error:


    MTOUCH: Error MT2002: Failed to resolve "System.Void ObjCRuntime.UserDelegateTypeAttribute::.ctor(System.Type)" reference from "Xamarin.iOS, Version=, Culture=neutral, PublicKeyToken=84e04ff9cfb79065" (MT2002) (xxx.iOS)


    Anyone can shed some light into this please? I have installed UI by manually referencing needed dlls as per docs here:

    Ok, after a few hours spent debugging this I think I found what the issue is.

    ObjCRuntime.UserDelegateTypeAttribute has been added in Xamarin.iOS 9.99. I'm using an older version of Xamarin.iOS and can't upgrade at the moment because of other dependencies. And I can't download an older version of UI for Xamarin Cross Platform.

    It would be nice if the documentation or release notes, or somewhere on the website it specified the require versions of Xamarin.iOS, Xamarin.Android and Xamarin.Forms. I would not have purchased it if I knew it didn't support the version I was using.

    Did you find a solution?

    I have the exact same problem. Would rather not upgrade Xamarin yet because the latest "stable" build has many issues and is anything but stable. Even service release 0 leaves many of these unaddressed.

    I don't have it working yet but I think I know what I need to get it working. I used version number 2016.1.113 of the trial component and it worked fine with my Xamarin setup. But I can't download that version of the paid component from the Telerik website. I submitted a support ticket, called them on the phone, and they say they need to backdate my license in order for me to get access to earlier versions, but they have some reason their system won't let them to that. 

    So I'm stuck waiting on them.

    Hi Alex and Vincent,

    Trial products are not provided for previous releases in the product's downloads page, only the current release is available as a trial. However, you can request a previous version be provided in a support ticket.

    I see that you have done this already, someone from the engineering team will respond to that ticket thread directly and provide the requested release.

    If you also need such a requirement, please open a support ticket here and request the specific version you need.

    Note that is not the case for a paid license. You get the full release history, internal builds and betas for the amount of time that your license was active. For example, your trial runs out in 24 days, so if you purchased a UI for Xamarin license for 10-2016 to 10-2017, you'll always be able to download versions in that time frame as the licensing is perpetual.

    I hope I was able to clarify this for you, please let us know if you have any further questions.
