Hi everyone!

James, cool, very interesting!!

Can you write down some use cases? I see in your tests that you can invoke javascript code from .NET, but can you expose a .NET object to V8/Javascript and use it from JavaScript code? expose a Type? declare an static method in .NET as a function to V8? I would like to do

if (System.IO.Exists("..."))

...

var lines = System.IO.File.ReadAllLines("...")

....

from JavaScript. Or reference the System.Console as "myconsole" in JavaScript.

Difference with

http://javascriptdotnet.codeplex.com/

http://clearscript.codeplex.com/

?

Hi,

Ok, it's now possible to wrap CLR types in V8.NET. ;)  Although the focus of V8.NET was to interface at a lower level, I've added this feature to make it easier to consume existing .NET types.  For example:

{V8Engine}.GlobalObject.SetProperty(typeof(System.IO.File), null, true, V8PropertyAttributes.Locked);

In script: "File.Exists(...)"

or

{V8Engine}.GlobalObject.SetProperty(typeof(System.IO.File), "System.IO.File", true, V8PropertyAttributes.Locked);

In script: "this["System.IO.File"].Exists(...)"

V8.NET implicitly calls {V8Engine}.RegisterType() to register types, but you can call this before hand if you want more control over member attributes and recursive binding.

The type binding system is very efficient, and caches anything it can to speed up the process of working with the .NET side.
