Can't find PInvoke DLL 'dbnetlib.dll'

Hi,

I need a connection string with SQL 2014.

My platform is MK3100 ( Windows Embedded Compact) and VS2008Sp1.

I wrote the following code:

string connString = "Server=172.16.12.14;Database=Hotel;User Id=sa;Password=1234;";

SqlConnection connection = new SqlConnection(connString);

 

connection.Open();

I fund the following error code"Can't find PInvoke DLL 'dbnetlib.dll'".

Please help me

Regards

Homayoon
