As long as you use parameterized queries or a ORM like NHibernate or Entity Framework you don't have to do anything to prevent SQL injection. Parameters are passed to the server outside the actual SQL statement, as part of the RPC call to the server.

SQL Injection is possible only if you create a SQL statement by concatenating string values.

That said, you still have to be wary of user input to prevent script injection attacks. Fortunately, ASP.NET MVC already provides a request validation mechanism (see Understanding Request Validation).
