Code first does not support stored procedures.

You can execute scripts in a database initialiser using:

string sql = "CREATE PROCEDURE [MyProc]...";
context.Database.ExecuteSqlCommand(sql);

You can execute procedures them from the context like so:

string command = "EXEC MyProc";
IEnumerable<T> results = context.Database.SqlQuery<T>(command, null);

Personally, I wrap this up into a nice OO model. I have specialised SP class with strongly typed methods. These methods are decorated with an attribute that tells the DB initialiser to create a stored procedure of a given name from a given source. The strong type methods call the stored procedure.
