RussianQuestion
The lastest release (0.9 Stable) of the Dynamic Language Runtime contains IronPython and IronRuby, but it doesn't contain Managed JScript.
Does anyone know where I can download the latest release of Managed JScript for use with ASP.NET and/or WPF?
In case you aren't aware, JScript.NET and Managed JScript are too different things. What I'm looking for is Managed JScript.
Solution
Update...
The Silverlight Dynamic Language SDK 0.5.0 Release Notes posted March 23rd, 2009 on CodePlex, contained this little gem:
Managed JScript has been removed from the package.
When asked in this thread about the future of Managed JScript (IronJScript), Bill (billchi), a coordinator on the Dynamic Language Runtime forum, had the following to say:
The DLR JScript was experimental for informing the design of the DLR (expression trees, interop, callsites, hosting, etc.). The JS we released with asp futures and the Silverlight dynamic sdk became very old and unserviceable as the DLR continued evolving for release in CLR 4.0. Unfortunately, there are no plans at this time to develop and release a DLR-hostable JScript.
Thanks,
Bill
(edit to add quote from a later post)
The JScript team will continue supporting using native Jscript (jscript.dll) with IActiveScript. They’ll also continue to service Jscript.NET, but they aren’t making other commitments at this point.
Bill
Considering the JScript.NET scripting API's are now all obsolete (though they are still present in .NET 2.0), there therefore appears to be no .NET upgrade path off of the ActiveScripting implementation of JScript (JavaScript).
May I suggest that discussion (protest ;-) be directed to that thread.
OTHER TIPS
Never fear, Fredrik Holmström is working on IronJS, an implementation of JavaScript on the DLR in F#. He's currently targeting .NET 2.0, 3.5, and 4.0, as well as Mono 2.6, but would eventually like to get to Silverlight integration when the library becomes more stable.
Rumor this week out of the Redmond "Metro" DotNet futures conference is that MSFT decided to kill ManagedJScript on the DLR.
That's the reason we aren't hearing anything about it.
You can find it in the ASP.NET Futures
According to this blog post, Managed JScript is delivered as part of Silverlight 2 (1.1). To write applications you'll want the Dynamic Language SDK.
edit: For ASP.NET, it is available in the ASP.NET Futures but that has been "retired" according to this entry and isn't currently available in another official release.
Managed JScript been really hard to find relative to IronPython or IronRuby. Pretty much the only place to find it is the ASP.Net futures. But that's two years old now and not supported. ECMAScript 5 is getting standardized right now and should be done some time in 2009. Maybe Microsoft is waiting until the new standard is out.
Have you seen ROScript? http://www.remobjects.com/script.aspx Supposed to support both ECMAScirpt and PascalScript
