Unfortunately, these are the limitations for IronPython in this CTP (Community Technology Preview) release. There are very limited intellisense and debugging support currently. Event-autogeneration are not supported at all. You could leverage html schema intellisense in source view and property grid for controls in design view for some quick reference on properties and events. I appologize for the inconvenience. We'll try to complete these features in our next release.
Please check out the last section of readme.htm from installation directory for more limitations.
Thank you for trying this out and reporting issues! We appreciate and will try to fix the problems as soon as we can.
Thanks!
