title: Implement CRUD operations with big JSON file in .NET
body: <p>I have big (about 1 GB) JSON files and I want to implement CRUD operations in  the most efficient way. Deserializing json to a list of appropriate objects for implementing CRUD operations - like 
  <code>List&lt;object&gt; listObjects= new JavaScriptSerializer().Deserialize&lt;List&lt;object&gt;&gt;(json)</code> - then serializing is very slow.</p>
  
  <p>Is there way to do this or any api?</p>
