I'm programming an AddIn for Solid Edge using the SolidEdge Community AddIn. With this AddIn, an EdgeBar containing a website should be displayed.
Because I don't want to use the standard Windows Forms WebBrowser control (it only uses the IE rendering engine), I try to use the Chromium Embedded Framework with its .NET bindings CEFSharp (https://github.com/cefsharp/CefSharp).
When creating a fresh Windows Forms Application, embedding the CEFSharp control works just fine. But when I embed it in my AddIn code, I receive this following error after starting Solid Edge with the AddIn activated and the program crashes:
An unhandled exception of type 'System.ArgumentException' occurred in mscorlib.dll
Additional information: Cannot pass a GCHandle across AppDomains.
I found a similar CEFSharp issue dealing with the AppDomain-problem (https://github.com/cefsharp/CefSharp/issues/351), but I don't really see a solution for my problem.
(Notes: Target Framework is .NET Framework 4.5, Output type Class Library. I'm using Visual Studio 2013, programming language is C#).
This pull request (https://github.com/cefsharp/CefSharp/pull/1556) fully solves my problem. Because it hasn't made its way to CefSharp's master yet, I built it myself and everything works :-)
Let's hope this will be in release branch soon so no one will have to cope with this problem anymore.
