I'm using FileHelpers for reading csv files, and all it was ok until I switched from VS dev server to IIS, I get a "PolicyException: Required permissions cannot be acquired", I googled and found that I need to add Reflection Permission for this to work, anybody knows how ?

Your asp.net application is probably running in low-trust or medium trust. Reflection permission is in full trust.

You can enable this specific Reflection Permission without going full trust by following this post by Rick Strahl :

Note: it might not work if you're hosted and don't have permissions to override some security settings.

  • I don't know, I get this policy exception even when I put Full trust, I'm on a local machine with my own IIS7, Windows 7, VS2008 – Omu Dec 04 '09 at 12:10

    it was the Load User Profile property from DefaultAppPool AdvanceSettings, I had to set it to true. – Omu Dec 07 '09 at 07:28
