Persisting and Restoring Application State

Isolated Storage

A standard Windows application can have full access to the computer (depending on user security settings), so there are many options for storing data, such as using the Windows Registry or the local file system. But an attractive alternative to these classic approaches is to use the .NET Framework’s isolated storage technology. Besides being easy to use, the same techniques work in all environments in which managed code can run, such as in a Silverlight application or a XAML Browser Application (covered later in this chapter).

For desktop apps, isolated storage is a data storage mechanism that provides isolation and safety by defining standardized ways of associating code with saved data. Standardization provides other benefits as well. Administrators can use tools designed to manipulate isolated storage to configure file storage space, set security policies, and delete unused data. With isolated storage, your code no longer needs unique paths to specify safe locations in the file system, and data is protected from other applications that only have isolated storage access. Hard-coded information that indicates where an application's storage area is located is unnecessary.

Alternative to IValueConvert, QuickConverter

https://quickconverter.codeplex.com/ Quick Setup Steps Add the assembly reference to your project. This can also easily be done using  the NuGet package . Add the namespaces to Quick Converter that it will need to know about (before any xaml that uses it is loaded). e.g. In your WPF application's App.xaml.cs file: public   partial   class   App  :  Application { public  App() :  base () { // Setup Quick Converter. // Add the System namespace so we can use primitive types (i.e. int, etc.). QuickConverter. EquationTokenizer .AddNamespace( typeof ( object )); // Add the System.Windows namespace so we can use Visibility.Collapsed, etc. QuickConverter. EquationTokenizer .AddNamespace( typeof (System.Windows. Visibility )); } } Add the Quick Converter namespace to your xaml files so you can ref...
