[Ironpython-users] Problem with embedding IronPython into Silverlight Application

[Keith Rome]

Does this not work for you?

using IronPython.Hosting;
// ...
_python = Python.CreateEngine();

I believe that should handle the simple/typical scenarios, unless you need to alter the environment (such as plugging in a custom Host/PAL).

If you need to customize the environment, then this should work:

var options = new Dictionary<string, object>();
ScriptRuntimeSetup setup = Python.CreateRuntimeSetup(options);
_runtime = new ScriptRuntime(setup);
_python = Python.GetEngine(_runtime);


This code should work exactly the same on desktop CLR and Silverlight.

Subject: [Ironpython-users] Problem with embedding IronPython into Silverlight Application

Hi,

I'm new to scripting and would like to add support for IronPython to our Silverlight application, I have tried to find an answer on the net but could not find anyone else facing the same problem. The app is an out of browser application.

I've added the latest release (2.7.2) from nuget, checked that the binaries being used is from the SL5 libs-catalog: IronPython.2.7.2\lib\Sl5

The code I use to create the scripting engine is the following:

..

            _runtime = new ScriptRuntime(DynamicEngine.CreateRuntimeSetup(true));

            _python = _runtime.GetEngine("py");
..

When GetEngine is executed I'll the following secutiry exception:

"{System.MethodAccessException: Attempt by security transparent method 'IronPython.Modules.SysModule.GetPrefix()' to access security critical method 'System.Reflection.Assembly.get_Location()' failed.
   at IronPython.Modules.SysModule.GetPrefix()
   at IronPython.Modules.SysModule..cctor()}"

When checking the code at GitHub for the method: GetPrefix()

There are code checking a compiler-constant that seems to be if you running in "silverlight" (don't have diskaccess to the libs), but the code seems to be executed anyway, which makes me wonder if I still doesn't use the correct libs for Silverlight.


Would really appreciate if someone could point me in the right direction.


Have a nice day!
