Are you sure you need ASP.NET 2.0, not 4.0?

The error is saying that you are trying to execute a SQL statement against a connection that is not quite ready yet. Can you post the code that is causing this issue?

i will use connection where on every page load

if (!IsPostBack)
{
c.setcon();
}

and use Appcode :
public void setcon()
{
try
{

con = new SqlConnection();
con.ConnectionString = @"Data Source=DATA-SERVER;Initial Catalog=fmweb;User ID=sa";
if (con.State == ConnectionState.Closed)
{
con.Open();
}
}
catch (Exception e1)
{
e1.Message.ToString();
}

}

error of ExecuteNonQuery requires an open and available Connection. The connection's current state is closed. when logout button click.

Class1.document_reader = "No Document Read";
Class1.sign_out=System.Convert.ToString(DateTime.Now);
string s = "insert into User_log values('" +lbl_uname.Text+ "','" + string.Format("{0:dd/MM/YYYY}",Class1.sign_in)+ "','" + string.Format("{0:dd/MM/YYYY}",Class1.sign_out) + "','" + (Class1.document_reader) + "')";
SqlCommand cmd = new SqlCommand(s, c.getcon());
cmd.ExecuteNonQuery();
Session.Abandon();
Response.Redirect("default.aspx");
