title: Customize T4 template - ADO.Net Entity data model for EF code first from existing database
body: <p>I am trying to locate and customize the T4 template of ADO.Net Entity data model for EF code first from existing database.</p>
  
  <p>What I want to customize or change is data type mapping. I am using Oracle's ODP.Net provider which supports EF. I am trying to remap the Oracle data type number to Int64 instead of Decimal due to my requirement.</p>
  
  <p>As I am new to editing T4 files for customization I am finding difficulty in locating the template file that does the code first mapping. Any help in pointing me to the right direction is appreciated.<a href="https://i.stack.imgur.com/jSerH.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/jSerH.png" alt="enter image description here"></a></p>
