The word is, I would like to run my C# app on a computer with Windows XP and SQL Server 2008 R2 Express installed. Although I tried any possible connection strings, I could not run my App on that computer. Any help will be highly appreciated.
I tried these connections strings:
Data Source=(local); integrated security=SSPI; database=SepidarDatabase.mdf
server=.\SQLEXPRESS;integrated security=SSPI;database=SepidarDatabase.mdf
"Data Source=.\SQLEXPRESS;SepidarDatabase.mdf;Integrated Security=True"
providerName="System.Data.SqlClient"
They all throw an exception error:
Invalid Value Key for "attachDbFileName"!
