asp.net - Where can you download Managed JScript for the DLR?

Question

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.

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.

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.
