This post will start the series of "did you know that..." posts. Where I'll try to show things that may be useful for developers and other people connected with IT.
Did you know that "Internal .Net Framework Data Provider error 6" can happen when you use the SQL Native Client data provider to connect to an instance of SQL Server 2005 that is configured to use database mirroring. The solution to this situation is here.
Did you know that "the CPU on a computer that is running the NET Framework 2.0 consumes excessive system resources when you marshal an object array across a domain boundary"?
The solution provided doesn't result in installing hotfixes. But it can force the developer to redesign the app or sacrifice its performance. Both variants are bad :(.
