there is infinite recusrive calls in your properties Get & Set like:

string Lname{ 
    get { return Lname; } 
    set { Lname = value; }
}

Lname = value; will call your property again & again.

    public Customers()
    {
        int CustomerID = 0;
        string Fname = string.Empty;
        string Lname = string.Empty;
        string Country = string.Empty;
    }

    public int CustomerID { get; set; }

    public string Fname { get; set; }

    public string Lname { get; set; }

    public string Country  { get; set; }

}

Try the following:

public class Customers
{

    private int _CustomerID; 
    private string _Fname;
    private string _Lname;
    private string _Country;

    public Customers()    
    {        
        int CustomerID = 0;        
        string Fname = string.Empty;        
        string Lname = string.Empty;        
        string Country = string.Empty;    
    }    

    public int CustomerID    
    {        
        get { return _CustomerID; }        
        set { _CustomerID = value; }    
    }    

    public string Fname    
    {        
        get { return _Fname; }        
        set { _Fname = value; }
    }    

    public string Lname    
    {        
        get { return _Lname; }        
        set { _Lname = value; }    
    }    

    public string Country    
    {        
        get { return _Country; }        
        set { _Country = value; }    
    }

public int CustomerID
{
    get { return CustomerID; }
    set { CustomerID = value; }
}

You are assigning the value to itself recursively. And the same for the other properties.

You need to define a backup field with another name, for example:

private int _CustomerId;
public int CustomerID
{
    get { return _CustomerID; }
    set { _CustomerID = value; }
}

Or even better:

public int CustomerId {get; set;}
