c# - Connecting to Sharepoint Services 3 via SDK: Getting 500 - Internal Server Error on ExecuteQuery() -

this first time using sharepoint sdk, , i'm having hard time getting things connected...

the background sharepoint site project portal in tfs 2010. sharepoint services 3.0.

i have simple function i'm trying run:

using sp = microsoft.sharepoint.client;  class program {   static void main(string[] args)   {     using (sp.clientcontext ctx = new sp.clientcontext("http://<hostname>/sites/projects"))     {       sp.web web = ctx.web;        ctx.load(web);       ctx.load(web.lists);        ctx.executequery();        foreach (var list in web.lists)       {         console.writeline("list name: {0}", list.title);       }      }      console.readline();   } } 

on executequery() call, returns 500 - internal server error. ideas might going on?

thanks!
