http://ironpython.codeplex.com/workitem/32596
User KeithJRome has proposed the issue:

"Initializing the Silverlight 4 or 5 version of IronPython throws MethodAccessException while running in a browser context (might not for out-of-browser, but this is unconfirmed).

Repro code:

IronPython.Hosting.Python.CreateEngine();


Outer Exception TargetInvocationException: Failed to load language 'IronPython 2.7.2': The type initializer for 'IronPython.Modules.Builtin' threw an exception.
   at Microsoft.Scripting.Runtime.LanguageConfiguration.LoadLanguageContext(ScriptDomainManager domainManager, Boolean& alreadyLoaded)
   at Microsoft.Scripting.Runtime.DlrConfiguration.LoadLanguageContext(ScriptDomainManager manager, LanguageConfiguration config)

2. [New comment] IronPython engine fails to load under Silverlight (MethodAccessException)
http://ironpython.codeplex.com/workitem/32596
User mahlenius has commented on the issue:

"I'm having the same problem with an out of browser application in Silverlight 5. 

I think the code works in SL5, if the binaries are recompiled to target SL5. 

Attached a small test project, which mimic the code in GetPrefix() and it throws an exception when compiling => SL4 but works just fine when the target is set to SL5.
