SQL Server 2005/ ADO.NET 2.0 Begin Transaction Issue

[Guest]

I have an application that was originally built in VS 2003 and successfully
running against SQL Server 2000 and SQL Server 2005 (June CTP). Recently, we
migrated to VS 2005 Beta 2 and are running on SQL Server 2005 (June CTP)
exclusively. Since the migration, we have some situations where we receive
the following exception when attempting to begin a SQLTransaction:

Exception Type: System.Data.SqlClient.SqlException
Number: 3988
Message: New transaction is not allowed because there are other threads
running in the session

Stack Trace:

I haven't been able to find any information about this error and I was
wondering if anyone had ideas about the cause of the exception and why it is
an issue with VS 2005 Beta 2 but not in VS 2003.
