Unrecognized attribute 'requirePermission' error

I am getting following error:

Unrecognized attribute 'requirePermission' from machine.config file.

When i trying to login 开发者_StackOverflow社区by using WCF services from Windows application which is developed in 1.1.

Please help.

Regards.

That would indicate that whatever xml schema your config file uses does not include the requirePermission element.

What exactly were your steps in producing the error? Maybe go back a step at a time, and find out which step caused it. Or be more specific in your question.
