Using awesomium (or chromium), is it possible to load content from the file system?
Maybe by using ajax or some other method?

What do you mean by "load"? Query a rest service? Display an HTML page? – BradleyDotNET Mar 20 '15 at 22:24

For example: If there is a file in the local file system with the url `file://file.txt`. Can I load the contents of that file into a javascript variable? – Paul Nikonowicz Mar 20 '15 at 22:33

1Without the user giving you access to it, I very much doubt it. If you control the client system, You could easily read it with C# and invoke a javascript function with the contents though. – BradleyDotNET Mar 20 '15 at 22:35

Websites in Awesomium/Chromium, just like normal websites, operate in a sandbox. This means that without the user explicitly "giving" you a file, there is no way to access it.
However, your WPF application could easily read such a file and pass its contents to the web page using the awesomium control.
You use CallJavascriptFunction:
JSValue fileText = new JSValue(fileText);
webView.CallJavascriptFunction("someMethod", fileText );

If you want to go the other way, see Can I call application methods from JavaScript in Awesomium?
