Exception of type 'System.ComponentModel.Design.ExceptionCollection' was thrown

After several hours of figuring out on how to solve this error when opening a Windows Form in Form Designer in my Visual Studio project, I found out that the problem is due to incorrect version of the third party control that I am using.

I have a client who has DevExpress control version 11.2.7 and mine was 11.2.10. I search the internet and no answer was found.

This problem is also the same with my previous post “The definition of the report 'Main Report' is invalid”. Though, the error is different, but the solution is the same.

All you need is remove the reference from My Project properties and change it with the correct version.
