[IronPython] Specified language provider type is not registered.

[KE]

Oh D'uh, Thanks!

 

It got further now, but I had built the binaries in Debug mode and there was
an Environment permission exception in:

 

internal static class DebugOptions {

        private static string ReadDebugString(string name) {

#if DEBUG && !SILVERLIGHT

            try {

                return Environment.GetEnvironmentVariable("DLR_" + name);

 

Of course, I will go back and build in Release mode, but I thought it's
something you should know - the assembly acts differently in partial trust
based on the type of release mode.

Thanks,

The problem in your code is that you update "setup" variable after it is
passed to ScriptRuntime. You need to first initialize the setup and then
pass it to runtime ctor (the ctor uses the setup object to create and
configure DLR and once that done no changes are possible).

 

setup.LanguageSetups.Add(Python.CreateLanguageSetup(null));

ScriptRuntime runtime = new ScriptRuntime(setup);

Does this work?

Get the ScriptEngine directly from IronPython.Hosting.Python instead of
going through the runtime.

Hi, I've compiled IronPython from the latest source code, and added some
strong name keys to run in a partial trust AppDomain, but I can't quite get
the ScriptEngine created:

System.ArgumentException: Unknown language name: 'py'
  at Microsoft.Scripting.Hosting.ScriptRuntime.GetEngine(String
languageName)
  at mycode

The code creating this is:

ScriptRuntimeSetup setup = new ScriptRuntimeSetup();
ScriptRuntime runtime = new ScriptRuntime(setup);
setup.LanguageSetups.Add(Python.CreateLanguageSetup(null));
runtime.LoadAssembly(assembly);
runtime.IO.SetOutput(ms, writer);
ScriptEngine engine = runtime.GetEngine("py");
ScriptScope scope = engine.CreateScope();


I would prefer to do this programmatically, without any external .config
files, if possible.
Thanks!
