Flash vs Silverlight on Localhost /local file permission to access remote webservice

In Flash user can give permission to localhost and even local html file to access remote webservice.

I fail to see the same thing for Silverlight which is a nightmare for testing on lo开发者_Python百科cal pc.

Could you explain what you are not able to accomplish?

I can access local and remote webservices from a local Silverlight app easily as long as a cross domain policy file is correctly configured.
