You are developing a Windows Presentation Foundation (WPF) application. You are implementing the security features for a function that requires File 10. The callers of this function that are higher in the stack do not have permission to read the C:\temp directory. The function also accesses other resources that require permission. You need to ensure that the function has the proper permissions to read the C:\temp directory, and that all other resources in the function can still be accessed. Which attribute should you include with the function?
