I had a bad experience with
localDB
too, couldn't get it working.
If you can manage without a real database, and don't have lot's of data, you could use
XML
to store your data.
My database of choice at the moment is
PostgreSQL
in combination with
NpgSql
in C#, it is not as bloated as
SQL Server
, runs on different platforms, and there is even a portable version.
An alternative might be
SQLite
, here is a tutorial:
