While most common types can be serialized in one of two ways listed above, there are some types that may not. In such cases, you have a few different options:

• Implement a TypeConverter for the type that can convert to and from string. The implementation can use a suitable serialization mechanism like one of the formatters/serializers that ship in the Framework or any custom mechanism you wish. You can then specify this converter on the type itself or on the property in your settings class.
• Specify a particular SettingsSerializeAs enum value using a SettingsSerializeAsAttribute. For example, if you wish to serialize a setting in binary format, simply specify SettingsSerializeAs.Binary.
