If you don’t want to write direct SQL queries, then another option is ORMs like:

1. Entity Framework
2. Linq to SQL

Depending on how much database interactions you need, you may find the few lines to execute a SQL command query directly easier. If you need to do quite a bit of DB interactions with objects then an ORM may be more productive for you.

Code samples are outside the scope of a question because you need to setup mappings etc… but here’s a getting started with tutorial: http://msdn.microsoft.com/en-us/library/bb386876.aspx
