Exception loading CEFSHARP.CORE.DLL
On some of our machines, we get an exception when trying to start CefBrowser from WPF code. I tried to troubleshoot this problem, but I can't figure out what is going wrong. All Win7 machines run 64-bit OS.
Below I have recorded a trace using "Dependency Walker" running "CefSharp.MinimalExample.Wpf.exe". (Sorry for the formatting, I don't know how to improve it.)
It launches and then turns into a standard text application "Could not load file or assembly 'CefSharp.Core.dll' or one of its dependencies. The specified module could not be found."
So - does anyone know what to do next? I can't guess!

For those still looking for a solution to this problem, the simplest task is to download and install Visual C ++ 2012 if you are using CefSharp from version 55 down and Visual C ++ 2013 if you are using CefSharp version 57. Make sure you installed VC ++ assembly (x86 or x64) depending on the target architecture of the application (assembly). It took me a day and a half to figure it out.
