Do you need all of the security goo? My guess would be that all of this isn't necessary. It should only be necessary if you're running in a partial trust scenario where your assembly is capable of asserting permissions. That could be the case if you're in ASP.NET's medium trust. Otherwise it should make no difference. If you do need this you may be unable to do this w/ IronPython. The assert is associated with a stack frame and we'll actually perform the call to assert inside of another method, unwind the stack, and then it'll be gone. My best guess is you'd need to have a C# wrapper for this to work from partial trust in ASP.NET. _______________________________________________ Users mailing list [email protected] http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
