c# - Simple .NET file system persistence? -

i need store simple data (just poco objects few attributes, nothing fancy).

public class mypoco {     public int id {get; set;}     public string title {get; set;}     public string email {get; set;}     // ... } 

basically, @ point of web application need check if mypoco object persisted (matching id), , if it's not, persist it. that's need.

it can't database, xml or json. what's easy way (or nuget package) store it?

i suggest use in-process database sql server ce or sqlite o/r mapper. easier , more maintainable reinventing small database.
