I get the same problem.

Another symptom is that "import System" fails if you don't AddReference first. never needed to do that for IPy 1.1 and don't need to either when running ipy 2.0.


When embedding IronPython you need to add references to both 'System.dll' and 'mscorlib.dll'. This is done for you in the console, but not when embedding IronPython.

You can do this using the 'LoadAssembly' method of the ScriptRuntime:

_runtime.LoadAssembly(typeof(String).Assembly);
_runtime.LoadAssembly(typeof(Uri).Assembly);

It fails with my hosting code, and also reproduces with the "hello world" hosting sample:
http://blogs.msdn.com/seshadripv/archive/2008/09/11/dlr-hosting-sample-simple-dlr-host-using-the-new-app-config-based-scriptruntime-creation.aspx

The only changes I made to the sample were
1) delete ruby configuration from App.config and the line of code that builds a ruby engine (I don't have the assemblies for ruby)
2) change the line defining the source code to:
ScriptSource source = pyEng.CreateScriptSourceFromString(@"import System", SourceCodeKind.Statements); 3) remove the code that gets the "output" variable from pyEng (since we don't produce it)

like I said, this fails with "No module named System".
If you add a clr.AddReference("System"), then import works, but dir() seems to only show namespaces and not types, so import System.DateTime will fail.

I'm now looking at sources for IronPythonConsole to see what the difference is, but if someone knows what I'm doing wrong, please tell...

thanks

    I am migrating from 1.1 and have been unable to import System.Math

    clr.AddReference("System")
