title: Role of Designer.cs File in c#
body: <p>I am getting Designer.cs file in my project and the comment in the file says it is being generated by an automatic tool.  </p>
  
  <p>This was an existing project so I don't know much about that. It is generated for one schema.cs which consists of schemas of all the tables in Database.  </p>
  
  <p>I am using a SQLIte DB.
  Can any one help me in understanding what is the use of the <code>Designer.cs</code> file in a C# project.</p>
