Error: The name 'SqlHelper' does not exist...

Error 1 The name 'SqlHelper' does not exist in the current context d:\work\cwork\pool\pooling\pooling\pooling.cs 25 28 pooling

It's a simple console application test solution with only 2 cs files:

pooling.cs
SqlHelper.cs

SqlHelper is supposed to be a class file.

Pooling.cs contains the main method as follows:
**********
static void Main(string[] args)
{
while (true)
{
// error line
SqlDataReader dr = SqlHelper.ExecuteReader(connString,
CommandType.Text, "select date = getdate()");
// error line
if (dr != null)
{
while (dr.Read())
{
Console.WriteLine(dr["date"].ToString());
}
dr.Close();
}
Console.WriteLine("Press Enter to continue...\n");
Console.ReadLine();
}
}

********

In the SqlHelper.cs file, the class is as follows:

********
using .....;

namespace pooling
{
public class SqlHelper
{
private static Int32 NUM_TRIES ;
private const Int32 MAX_TRIES = 32;

static SqlHelper()
{
NUM_TRIES = 0;
}

//VARIOUS CODE
}

*********
How can I make SqlHelper 'visible' to the pooling.cs file?

Many thanks
Mike Thomas
