With Ninja Database Lite you have the choice of using Isolated Storage or File Storage.

 

Example in C#:

NinjaDbConfig config = new NinjaDbConfig();
string databasePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "MyApplication");
config.Storage = new FileDatabase(databasePath);
NinjaDb ninja = new NinjaDb(config);
 
Person person = new Person();
person.Name = "John";
person.PersonId = 1;
 
//Save
ninja.Save("Person1", person);
 
//Get Keys 
List<string> keys = ninja.GetKeys();
 
//Load
Person personCopy = ninja.Load<Person>("Person1");
 
//Delete
ninja.Delete("Person1");

Example in VB.NET:

Dim config As New NinjaDbConfig()
Dim databasePath As String = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "MyApplication")
config.Storage = New FileDatabase(databasePath)
Dim ninja As New NinjaDb(config)

Dim person As New Person()
person.Name = "John"
person.PersonId = 1

'Save
ninja.Save("Person1", person)

'Get Keys
Dim keys As List(Of String) = ninja.GetKeys()

'Load
Dim personCopy As Person = ninja.Load(Of Person)("Person1")

'Delete
ninja.Delete("Person1")
