Hello.
When I try to open context menu on the RadRichTextBox the exception occurs:

What can I do wrong? Thank you in advance.

Hello Alexander,

Please refer to this forum thread, which deals with the same problem. It is mainly an assembly references issue - you need to make sure you have referenced all necessary DLLs from one and the same version.
Sometimes, cleaning the solution or even deleting the obj and bin folders is also needed. We will do our best for find workaround for this MEF exception for the next release.
If the problem persists, do not hesitate to contact us again.
