C# timeout on database object

Question

I am getting a timeout message when accessing a linq to sql object in a C# 2010 application. This error message is occuring when I am doing a select in the linq to sql object. thus can you tell me how I can increase the timeout on the linq to sql data set object? The following is the error message I am getting:


Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.
