this is an erreur in my application or probleme with many connexion in SDF file ?

Answer 1

Depending on how your application behaves, you might be able to replace SQL Compact with SQLite . It can really only handle one write at a time but can handle multiple simultaneous reads. Anything more than that and you should be looking at a real SQL server.

Answer 2

You should look at a Microsoft Locking in SQL Server CE . In a nutshell, it says multi users/application can concurrently access the SDF at the same time provided the database is not locked in a transaction.

Also, I like to mentioned that we also do not have multi user/application access to a SQL Server CE 3.1 file on a network drive. (This constraint may still be true for SQL Server CE 3.5). If you're being affected by this, you will have to ensure your SDF is being opened using a local drive reference.
