FileNotFound Exception trying to init CefSharp browser control

Hello,

I have been trying to get CefSharp up and running on a taskpane addin for Microsoft Word. Currently when trying to run the program I am unable to get past: 

'The assembly with display name 'CefSharp.Core.Runtime' failed to load in the 'Load' binding context of the AppDomain with ID 2. The cause of the failure was: System.IO.FileNotFoundException: Could not load file or assembly 'CefSharp.Core.Runtime, Version=94.4.50.0, Culture=neutral, PublicKeyToken=40c4b6fc221f4138' or one of its dependencies. The system cannot find the file specified.'


I can confirm this package works on a regular WinForms project just not a AddinExpress project. I have tried unregistering/registering process etc. Any help on this would be appreciated. Can provide more info and demo app if need be.

Hello Rhys,

Please send us the sample project(s) to the support email address; find it in {Add-in Express installation folder}\readme.txt; please make sure your email contains a link to this topic.

Thank you file has sent. I have raised the question with the devs of the framework as well, this is what they said:


First step is to confirm if your plugin is going to be run in the default AppDomain. Because CefSharp is built with Visual C++ which only runs in the default AppDomain (won't work from a different one).

If you are then it should just be a matter of loading the libraries.

Hello Rhys,

Thank you.

An Add-in Express add-in loads into a separate domain. VSTO add-ins also use non-default domains.

Hi Andrei thanks for the reply! OK that at least settles this issue then. I will see if there's another framework or something that offers this functionality. I assume there is no work around?
