Today I upgraded to version 2015.1.7 and now when I try to run project I get "KeynotFound" exception with following stack trace…
at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
at DevExpress.Xpf.Core.ContainerLocker.UnlockContainer(WindowContainer container)
at DevExpress.Xpf.Core.ContainerLocker.<>c__DisplayClass2.<Release>b__0()
at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs)
at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)
Previously(i.e. 2015.1.6 binaries) my project was working without any exception or problem. As call stack is not giving much info, I'm clueless where the problem is. Is there any suggestion you can provide to detect the problem area?
will appreciate if you can revert back quickly on this. I'm stuck now as I'm not able to run application.
EDIT
I revert back to version 2015.1.6 binaries and projects start working again. So problem is surely related to upgrade only.

Hello,
Is it possible for you to provide us with a sample project demonstrating the issue? We will examine it and try to find the cause of this issue.
Thanks,
Kirill
Now the problem is I have already revert back to version 2015.1.6 in order to continue my work. will have to install this on another machine and check…
OK Krunal, we will wait for your response.
Hello Krunal,
I found a ticket where another customer describes a similar issue. He uses the LoadingDecorator in his project, and it seems that the issue is connected to it. We have fixed this behavior in that thread, but it is marked Private, and you will not have access to it. Since the issue is fixed in our controls, I think you can upgrade your components using the latest hotfix for v15.1.7, which includes the fix for that issue as well. Please try upgrading your components by using the installer from the following link and check whether the problem persists: DevExpressComponents-15.1.7.15281.exe. Please let me know your results.
Thanks,
Andrey
In my project also I have used LoadingDecorator and after applying this fix my project works properly in 15.1.7. So it seems you have identified the issue and fixed it. Good job!!!
I'm happy to hear that, Krunal! Thank you for informing us of your results.
I've posted my comment as an Answer to allow other customers to find it more easily.
Please do not hesitate to contact us if you have other questions.
