<p class=MsoNormal>Hi, I've compiled IronPython from the latest source code,
and added some<br>
strong name keys to run in a partial trust AppDomain, but I can't quite get<br>
the ScriptEngine created:<br>
<br>
System.ArgumentException: Unknown language name: 'py'<br>
at Microsoft.Scripting.Hosting.ScriptRuntime.GetEngine(String<br>
languageName)<br>
at mycode<br>
<br>
The code creating this is:<br>
<br>
ScriptRuntimeSetup setup = new ScriptRuntimeSetup();<br>
ScriptRuntime runtime = new ScriptRuntime(setup);<br>
setup.LanguageSetups.Add(Python.CreateLanguageSetup(null));<br>
runtime.LoadAssembly(assembly);<br>
runtime.IO.SetOutput(ms, writer);<br>
ScriptEngine engine = runtime.GetEngine("py");<br>
ScriptScope scope = engine.CreateScope();<br>
<br>
<br>
I would prefer to do this programmatically, without any external .config<br>
files, if possible.<br>
Thanks!<br>
