Transaction Scope some times partially commit Problem ? Why?

Quote:

Limitations of System.Transactions

The System.Transactions namespace is not supported by .NET Compact Framework 2.0. Therefore, implementation will be for the Windows desktop operating system only and will correspond with the .NET Framework 2.0, .NET Framework 3.0, .NET Framework 3.5 or .NET Framework 4.

Note that if there is a timeout, the System.Transactions infrastructure will call Rollback from a separate thread. The main thread will not know about a rollback occurring in the separate thread. The long transactions might see a non-deterministic behavior and partial commit scenarios. To resolve this, increase the timespan of the transaction scope object when you create the object.
