没有任何ORM的ASP.NET MVC是一个坏主意吗？

I am learning ASP.NET MVC now a days and I have found that most of the examples in ASP.NET MVC are with ORM. I don't have any issue in using ORM for my learning and personal project. But at my work we have worked only with ASP.NET web forms and we use stored procedures only. We have data access layer (simple c# classes) as interface between asp.net code behind page and stored procedures. Now if we want to use ASP.NET MVC, will it be a bad idea to do it without an ORM. As most of the MVC frameworks like rails/django have built-in ORMs, is it any harm to use our own data access layer with ASP.NET MVC. I don't want to have any database related activity like datareader, datatable in my controllers. Is there any other better solution?I am learning ASP.NET MVC now a days and I have
