permissions

I'm developing a DLL that uses WPF classes to make image manipulation. It works fine in my local environment, but when I try to use it in an hosted web site I retrieve this error:

Request for the permission of type 'System.Security.Permissions.MediaPermission, WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' failed.

exactly when I try to call the EndInit() of a BitmapImage object:

BitmapImage originalImage = new BitmapImage();
originalImage.BeginInit();
originalImage.CacheOption = BitmapCacheOption.OnLoad;
originalImage.UriSource = new Uri(physical_imagepath);
originalImage.EndInit();

Any suggestion?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
