Is There Any Difference Between SqlConnection.CreateCommand and new SqlCommand?

Question

In .Net, is there any functional difference between creating a new SqlCommand object and attaching a SqlConnection to it and calling CreateCo

Answer 1

Functionally they are exactly the same.

However, SqlConnection.CreateCommand() lets you be more agnostic about what type of DB you are using. For example instead of passing a SqlConnection instance around you could pass it around as a DbConnection which would yield a DbCommand.
