I am working on a project with support of multiple DB
1) Sql
2) My Sql
with .Net Core 2.
I will use DB as per client requirements.
I have a concern related to access layer performance, there are two options to use data access layer, either Entity Framework or Ado.Net.
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?
