Dictionary in Settings throws an exception?

I want to save a dictionary in the default UserSettings class of my project.

I've tried the following in the code of the Settings file but it fails:

<Setting Name="MediaKeys" Type="System.Collections.ObjectModel.Dictionary&lt;System.Input.Key, System.IO.FileInfo&gt;" Scope="User">
  <Value Profile="(Default)" />
</Setting>

I get this error message when I look at the UI for the Settings:

Could not load file or assembly 'System.IO.FileInfo>' or one of its dependencies. The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

Bearing in mind, please, that I will deal with the whole Serializable Dictionary at another point in time, why am I getting this exception? Even non-serializable objects (such as FileInfo, as I have tested) do not throw this exception.

.NET settings do not handle generics very well. This is what I do:

[XmlRoot("dictionary")]
public class MyDictionary : SerializableDictionary<int, string>
{
}
