Another epic #VisualStudio (or MS #dotnet development platform, or the project I'm working on) moment:
Every once in a while the app crashes on startup because it can't find #CefSharp. It's installed as a #NuGet package, right version and everything.
So I go to the NuGet folder, delete cefsharp.common, let it restore the package on build and everything is fine again (until it isn't anymore).
