VB.NET Exception : The type initializer for 'System.Transactions.Diagnostics.DiagnosticTrace' threw an exception.

Question

Hi,

I am getting Exception while connecting to database:

The type initializer for 'System.Transactions.Diagnostics.DiagnosticTrace' threw an exception.

My Code:

    Con = New OdbcConnection(ConnectionString)
    Con.Open()   ' **Geeting Exception here** 
    tmpdt.Clear()
    Cmd = New OdbcCommand(Str)
    Cmd.CommandType = CommandType.Text
    Cmd.Connection = Con
    Cmd.CommandTimeout = 0
    OdbcAd = New OdbcDataAdapter(Cmd)
    OdbcAd.Fill(tmpdt)

I read many solution but they all suggesting to delete congig.app file and rebuild. But i don't have config file. Please help.I am not getting any solution.
