title: Ado vs Entity Framework with .Net Core 2
body: <p>I am working on a project with support of multiple DB </p>
  
  <p>1) Sql</p>
  
  <p>2) My Sql</p>
  
  <p>with .Net Core 2.</p>
  
  <p>I will use DB as per client requirements.</p>
  
  <p>I have a concern related to access layer performance, there are two options to use data access layer, either Entity Framework or Ado.Net.</p>
  
  <p>As we know entity framework is bit slow for first request as compare to Ado.Net because EF loads metadata into memory, that takes a time. in .Net framework, But currently the mapper is no more in .Net Core so which one performance will be better either ado.Net of Ef with .Net Core2?</p>
