Please ignore my previous question. Sucessfully added FileIOPermission with PathDiscovery and it worked:<div><br></div><div><div> var pythonLibsPath = ExpressionEvaluator.GetPythonLibsPath();</div><div> permissionSet.AddPermission(new FileIOPermission(FileIOPermissionAccess.PathDiscovery | FileIOPermissionAccess.Read, pythonLibsPath));</div>
</div><div><br></div><div><br></div><div>Now I'm facing some problem with Emit permissions. Added ReflectionPermission(PermissionState.Unrestricted) but still doesn't work.</div><div><br></div><div>I'm using .NET 4 in this project at work. Sorry if the subject is too general and off-topic.</div>
