• Does this problem also occur in the CEF Sample Application

  • not test with original cef yet

Converting to discussion as this is not directly actionable in the context of CefSharp.

True if the file corresponds to a symbolic link. For Windows currently not supported and thus always false.

As per https://source.chromium.org/chromium/chromium/src/+/main:base/files/file.h;l=148?q=base%2Ffiles%2Ffile.h&ss=chromium

I believe you'll find this is a limitation of chromium. You also cannot run chromium from a network share. Those are all low level chromium error messages you are seeing, not directly in the CefSharp codebase.

For what it's worth you can load CefSharp from another folder e.g. as a plugin.

See https://github.com/amaitland/CefSharp.Caliburn.Micro.DemoApp for an example using .Net 5.0.
