Am getting that error and its seems with file inaccessibility. It happens when i try to concurrently write or read database file from different Threads(From different Instant of DBreezeEngine). Im using ASP.NET Webforms and every request will have different Instant of DBreezeEngine.
I tried to use DBIsoperable but the error happens before it.
Is there away to concurrently read/write db file from different DBreezeEngine instant?
