Question

I need to replace EF4.1 with ADO.NET. The data in our application is returned by stored procedures only. I need help re-writing calls like the following (in order to write a DAL for the application):

EF calling stored procedure:

using (var db = new NexGenContext())
{
   SqlParameter param = new SqlParameter("@ReviewID", Id);
   var issues = db.Database.SqlQuery<QuestionIssue>(
        "SP_GetQuestionIssues @ReviewID", param).ToList();

   return View(issues);
} 

What is the equivalent in ADO.NET? Get data from the database and map to my models?

Answer 1

The closest ADO.NET technology to being an ORM without actually crossing the line is data sets. Data sets act very much like an ORM in the way you can access data directly from a table without looping through a cursor. Data Sets return lists directly and can track new data vs old.

This link is a pretty good overview:

This MVC datasets with viewbags stack thread specifically addresses using Data Sets in Models.
