embedding javascript engine .net

just wondering anyone ever attempted embedding indeed integrating any js engine .net environment. i indeed (after lot pain effort, given it's graceful prehistoric definitely finished) spidermonkey-dotnet project. anyone trust area? engines squirrelfish, v8..

not i'm positive mozilla's spidermonkey (using rails-like miniframework tradition components inside core asp.net application), nonetheless i'd still adore try bit offer options. command-line solutions i'd need, i can't rest anything else clr, i need methods from/to javascript/c# objects.

// c# class
public category a
{
    open twine hello(string msg)
    {
        relapse msg + " whatewer";
    }
}

// js snippet
var = new a();
console.log(a.hello('call me')); // i have console.log implemented, don't worry, it's client-side formula :)

just explain - i'm perplexing indeed way the concentration itself server-side javascript. it's used wholly minute tradition user subapplications (can seen arrange dsl). it's many easier (and safer) grant normal programming js c#.
