Referring external DLLs in WPF crashing Application

Question

I have used following 3 SQL Server (Version SQL Server 2008 R2) DLLs in a WPF project:
Microsoft.SqlServer.ConnectionInfo
Microsoft.SqlServer.Management.Sdk.Sfc
Microsoft.SqlServer.Smo
Project works fine on the machine on which it was developed. However if I try to move the .exe to
some other machine then application gets crashed.
I have set CopyLocal=Truefor
all the 3 DLLs so that during compilation it should copy all the 3 DLLs inside Debug folder. (These DLLs are required to find out the SQL Server DATA Root Directory.)
Following the code which I am trying to execute in my App.
try
MessageBox.Show("trying to open connection");
string conStr = System.Configuration.ConfigurationManager.ConnectionStrings["MyConnectionString"].ToString();
con = new SqlConnection(conStr);
con.Open();
MessageBox.Show("connection opened ");
var serverConnection = new ServerConnection(con);
var server = new Server(serverConnection);
var defaultDataPath = string.IsNullOrEmpty(server.Settings.DefaultFile) ? server.MasterDBPath : server.Settings.DefaultFile;
var defaultLogPath = string.IsNullOrEmpty(server.Settings.DefaultLog) ? server.MasterDBLogPath : server.Settings.DefaultLog;
string restoreSql = @"RESTORE DATABASE [MyDB]
FROM DISK = '" + this.FilePath + @"'
WITH
MOVE 'MyDB' TO '" + defaultDataPath + @"\MyDB.mdf',
MOVE 'MyDB_Log' TO '" + defaultLogPath + @"\MyDB_Log.ldf',
RECOVERY, REPLACE, STATS = 10";
SqlCommand restoreCmd = new SqlCommand(restoreSql, con);
int status = restoreCmd.ExecuteNonQuery();
completedFlag = true;
catch (Exception ex)
MessageBox.Show("Database Restore Error: " + ex.Message, "Error", MessageBoxButton.OK, MessageBoxImage.Error);
finally
if (con.State == ConnectionState.Open)
con.Close();
if (completedFlag)
MessageBox.Show("Database restore successful.", "Information", MessageBoxButton.OK, MessageBoxImage.Information);
else
MessageBox.Show("SYSTEM ERROR: Failed restoring database.\nPlease restart SQL Server Service and try again.", "Error", MessageBoxButton.OK, MessageBoxImage.Error);
Not able to find out why my application is crashing.
NB

Answer 1

When you say "move the exe to some other machine".
Did you copy the dll as well?
If not then you need to.
You need the entire content of your debug or release folder copied onto the user's pc.
Hope that helps.
