I am developing an ASP.NET application in which I need to provide support for two databases, MySql and MS SQL Server 2005 and 2008 (one database will be used at a time).
-
How will I configure the ASP.NET app to connect with different databases without reinstalling the app (i.e. using configuration)?
-
How will I configure LINQ?
-
Shouldn’t I use NHibernate?
Here is better way of doing it: Multiple database support with Entity Framework.
