Error with Visual Studio 2010 - Please help me!!!!!!!

I am getting this error list when debugging my project also the project can not connect to sql server in debugging mode.

A first chance exception of type 'System.Configuration.ConfigurationErrorsException' occurred in System.Configuration.dll
A first chance exception of type 'System.FormatException' occurred in mscorlib.dll
A first chance exception of type 'System.ArgumentException' occurred in System.Data.dll
A first chance exception of type 'System.TypeInitializationException' occurred in System.Transactions.dll
A first chance exception of type 'System.IndexOutOfRangeException' occurred in System.Data.dll

Could you please post the code that directly relates to the error? That would greatly help anyone trying to help you. Also, what flavor of SQL server are you using?

Thanks I already solved this problem enabled sql debugging in the debug settings.
