• Question 272:

  You create a Visual Web Part in SharePoint Server 2010.

  MNEMONIC RULE: "access the local file system = custom code access" WSS_Medium will give you access to System.Security.Permissions.FileIOPermission, but it'll also give youaccess to a few other assemblies/namespaces. If the goal is to minimize the amount of privileges, then CAS is the way to go. Securing Web Parts in SharePoint Foundation http://msdn.microsoft.com/en-us/library/cc768613.aspx
