open outlook window to send email asp.net
===

I am writing a project in asp.net C# using Visual Studio 2010.
I want to write function, which opens outlook window to send email when user clicks a button. 

I tried this:

    using Outlook = Microsoft.Office.Interop.Outlook;
    
    Outlook.Application oApp    = new Outlook.Application ();
    Outlook._MailItem oMailItem = (Outlook._MailItem)oApp.CreateItem ( Outlook.OlItemType.olMailItem );
    oMailItem.To    = address;
    // body, bcc etc...
    oMailItem.Display ( true );

But compiler says there is no namespace Office inside namespace Microsoft. 
Actually Microsoft Office including Outlook fully installed in my computer.

Should I include Office library to Visual Studio?
How the problem can be solved?
