  • Is an Adnroid-based Phone a Suitable MP3 Player for Music Streamed over the Internet?

    - by James McFarland
    I am considering getting an HTC phone running Android from Verizon Wireless when I next upgrade my phone. I also have an online account with a music vendor, where I have rights to listen to my collection, but not download the MP3s. Further, I have an unlimited data plan and Wi-Fi, so I have full access to bandwidth volume without any concerns. I am especially interested in mounting my phone in a car kit, and streaming my online music to my car's sound system while driving. If you are experienced in this scenario, or have tried this scenario - Is is reasonable to expect my HTC Android phone to provide me with streaming music via my cell data plan anywhere I get cell service?

  • Thermal risks to other components when watercooling CPU

    - by B Sharp
    I recently ordered all the components for a new desktop system to replace my old, dying computer. I wanted to have a really quiet desktop, so I got a case rated for being quiet and opted to try a closed-system CPU water cooling kit (Antec Kuhler H2O 620) that was on sale for a very good price over the Thanksgiving weekend. Most of my components are still in transit, but I became somewhat worried when a friend mentioned that abandoning air cooling units can result in heat buildup inside the case due to heat generated by the video card and other components such as RAM, the northbridge, MOSFETs and voltage regulators radiating heat that the CPU fan would normally at least keep circulating around so it doesn't build up in localized areas. Is this a realistic problem? What other precautions should I take to remove heat from other components? Adding more case fans seems like it would get really noisy. Are there quiet alternatives?

  • How to split file on Windows 2003 using MS supported tool

    - by Rune
    Hi, Is it possible to split a large file into smaller files on Windows 2003 using a tool provided/supported/sanctioned by Microsoft? I see that there are a lot of freeware tools (various zip tools) for this task, but I need to move files off of a production server, thus would like to avoid tools I don't know if I can trust. I would much prefer some tool included in the Windows Server 2003 Resource Kit Tools or something along those lines. Does such a tool exist? Thank you.

  • Why do most routers not include local DNS?

    - by user785194
    I need to change my firewall/router, and I'd prefer something with built-in DNS to resolve queries on the local subnets. I've got a mixed Linux/Windows system, often with only one computer turned on, and I frequently have problems resolving local names. I don't want to keep a Linux box permanently on just for DNS, and I'd prefer to have DNS in my router appliance, which is always on. I search Google for this occasionally but never find anything. You always get the obvious answers - it's not possible, put everything in /etc/hosts, NetBIOS, dedicated box, etc. So what am I missing? Why don't "cheap" routers let you do this? I'm pretty sure that Cisco kit does this. Almost all cheap routers will let you do MAC address reservation, to let them assign static IP addresses for DHCP. So why can't they simply do DNS as well for everything on the local subnets, just passing through remote domains to the ISP?

  • Configuring IIS site to use HTTPS

    - by James
    I am working on a REST API which I have currently deployed on a Win XP Professional SP2 development machine running IIS 5.1. The site is currently being hosted on port 81 and being accessed via HTTP. I would now like to configure the site to stop using HTTP and use HTTPS only. I have developed a self-signed certificate using the SelfSSL.exe tool from the 6.0 Resource Kit Tools and set the Common Name to be the IP of my server (as it's a local development machine it has no domain name). I have also already configured the site to use SSL using the How To Set Up an HTTPS Service in IIS tutorial as my guide. However, whenever I try to access a resource in the API via HTTPS I get a 404. Any ideas?

  • HD 6970 Corrupted Video

    - by FailedDev
    considering this rig : i7 2600K 8GB RAM Corsair Vengeance kit 10-9-10-27 @1866 HD 4870 PSU Corsair AX 1200 I recently upgraded to a HD 6970 and I am getting the following - not so nice screens : http://imageshack.us/g/213/1000142z.jpg/ Had anyone any similar trouble at all? I am thinking that the card is DOA but could it also be the Mobo? Since I am in the BIOS I can't think how the mobo could be the problem. HD 4870 works perfect btw regardless of what I throw at it. Any way to prove that the card is OK? Thanks

  • How to diagnose RAM?

    - by x-man
    I have a java process that is aborted after a while with SIGSEGV. It started to happen after I upgraded the server with more RAM. Having tested on different JVMs I suspect it might be a hardware problem. But no problem was detected by memtest86. So, what else can I do to detect the source of the problem is? Should I take the RAM modules one by one to detect the faulty module? The server is running on 64bit OpenSuse11.3. The memory is not an ECC one it seems. I have a kit of this (3*4GB * 2 = 24GB): http://www.kingston.com/datasheets/KHX1600C9S3K2_8GX.pdf

  • Odd SVN Checkout failures occur frequenctly on VMWare virtual machines

    - by snowballhg
    We've recently been experiencing seemingly random SVN checkout failures on our Hudson build system. Google search has failed me; I'm hoping the super user community can help me out :-) We are occasionally receiving the following SVN error when our Hudson build jobs checkout source via the Hudson Subversion plug-in (which uses svn kit): ERROR: Failed to check out http://server/svnroot/trunk org.tmatesoft.svn.core.SVNException: svn: Processing REPORT request response failed: XML document structures must start and end within the same entity. (/svnroot/!svn/vcc/default) svn: REPORT request failed on '/svnroot/!svn/vcc/default' This issue seems to only occur when checking out from our Virtual Machines (Windows XP, Fedora 9, Fedora 12) using Hudson's SVN Plug-in. Systems that use the traditional SVN client seem to work. SVN Server version: 1.6.6 Hudson version: 1.377 Hudson SVN Plugin Version: 1.17 Has anyone dealt with this issue, or have any suggestions? Thanks

  • Hardware for Capturing Packets

    - by Kevin
    One of my clients is a small school district in Texas. Like any school, they often have problems with network'd peripherals such as printers, et al. It would be nice to be able to simply "listen" to what the printer and PC are saying to each other (or not saying more importantly)... The problem is that I can't find old-style "hubs" anymore, and even if I could, it's not a long-term solution. All of the devices that I have found to replicate the purpose of a simple hub are either $100+ or are difficult to throw into a networking tool kit (aka my backpack)... Now that hubs are dead, what's the new low-cost standard for simple packet capture in the networking world?

  • How can I get the Android SDK working with Eclipse in Ubuntu 9.10 64-bit?

    - by user30667
    I would like to tinker with the Android software development kit, and I have found out that it only support 32-bit versions of the Java Platform and Eclipse. I installed the ia32 Sun Java runtime environment and the 32-bit version of Eclipse. I also used the update-alternatives program to make a java 32-bit preference. Both of these seem to run fine. I also installed the Eclipse android plugins, but my problem lies in the SDK downloaded from Google. When I go to Eclipse preferences and try to tell it about my Android SDK location, there are no SDK targets listed. Has anyone else gotten this running on Ubuntu 9.10 64-bit? Thanks.

  • Wireless slow, but very odd

    - by Logman
    I have a HP Pavilion dv6 laptop, internet through the wireless timeouts. Even though it connects fine to the AP/router. The computer had a virus (searchnu?) and I backed up the usual and restored the laptop to factory image. Problem is after the restore the internet through the wireless the same still... and connected via wired and everything worked fine. I was able to update the whole system. Internet worked perfect, speed great. But the wireless still was pitiful. Ping tests with wireless are interesting: Google= 18ms Gmail= 18ms Yahoo= 1023ms 8.8.8.8=30ms Microsoft= Request Timed Out Bing= Request Timed Out msn= Request Timed Out even though I get 18ms with google, the pages take a long time to load. Is this a root kit? is it the wireless card in the laptop?

  • MS Clear Screen Saver doesn't work

    - by ufoq
    I have a problem with really exotic thing - Microsoft Clear Screen Saver. As it's name suggests, it's a screen saver, that's transparent (MS posted it as a part of W2k Resource Kit). When you move the mouse/hit a key, the "lock" dialog appears. I would like to use this to view servers desktops without need to log in. I tested it on my XP's, and it works flawlessy. But on W2K3 servers it doesn't work. After the screensaver timeout, the error message is displayed: "The Clear Screen Saver cannot display the user desktop after the workstation has been locked"

  • Slot load DVD burner options for standard desktop case

    - by Michael Kohne
    I need a new DVD burner (internal) for my father-in-law's computer. He's apparently broken the current one - he forgot to push the tray back in after doing something and hit it with his chair. Given this, I'd like to get him a slot-loading DVD burner, so as to avoid the problem entirely. I need an internal device, and I'll be mounting in a 5 1/4" bay. He doesn't need any super-spec device - as long as it can read/write all the standard formats, it's good. I see a few options at newegg.com, but they all have mixed reviews. Are there any out there that are generally seen as reliable? How does one go about mounting slimline devices in a standard 5 1/4" bay? Is there a standard faceplate kit for that?

  • My new Xbox 360 drive doesn't show up

    - by RobbieGee
    I bought an Xbox 360 Arcade version a while ago and today I got a 120GB drive from a shop that had a closedown sale. I put the drive on the side as per the picture on the back side of the drive. When I go to settings and look at memory, it only finds the built in memory chip, not the harddrive. Am I doing it correct? I have almost never used my Xbox so I'm not sure if there's anything more to it. I don't think I fitted the drive wrong either, it seems pretty much impossible to do it wrong. The box came with only the drive, it doesn't have any transfer kit or the likes.

  • Decrypting a TrueCrypt drive pulled from another machine

    - by Blakeg08
    I work in a corporate environment and we are now required to encrypt laptops. I have already encrypted about 5 or 6 out of 40. I still have a few questions before we go all out with TrueCrypt. Can I decrypt a hard drive by plugging it into my desktop using a data transfer kit? I tried this and the hard drive showed up asking me to format before using the volume. If I have the TRD from each laptop backed up do I still need to backup the volume headers? What else do I need to back up? Thanks.

  • Snapshot/Save GPU Drivers

    - by ashes999
    Since I'm running XP/32-bit, my GPU drivers are quite fragile. I've spent several hours trying to back up and restore from old versions, on at least two separate occasions. Writing down the device drivers is not enough. In the short term, I would like to somehow save, zip, backup, snapshot, or something so that if I need to reinstall my OS in the short-term, I have a reliable way to get the drivers. ATI's website doesn't have the install kit anymore, and I don't have it saved; I googled, but didn't find the exact same version. How can I backup/save my drivers so that I can reinstall them later?

  • Is there other usage of Comcast extension cable and splitter?

    - by Tim
    I have an unused Comcast high-speed internet self-install kit from 2006. It has two coils of extension cable, and a splitter, and some screws. The name of the cable is "extension cable" printed on the package. I wonder if that is its actual name? As ethernet cables are always useful, I wonder if the extension cables are totally worthless and should be tossed into a trash can? Or are they usable for some other purposes, or even sellable? Thanks! SVI Digital SV-2G Splitter (5/1000MHz): One interface of the cables: Screws

  • Is it possible to open several web pages when browser is started?

    - by gotqn
    I am searching for browser option or plugin (it will be best if it is available in Web Kit browsers,Opera or Firefox - not IE) that allows me to open several web pages when it is initially started. For example, let's say that I have some file with settings in which I have pointed the following websites: Google + gmail StackOverflow.com SuperUser.com dba.stackexchange.com linkedin etc... and when I firstly started the Chrome browser, all this sites will be opened in new tabs and because the browser has saved my passwords I will be logged in. I will find this very helpful because: It will saves me time I will not miss anything when I turn off my computer (for example to forget to check my mail)

  • Can I move files from a laptop hard drive with a corrupt sector to a USB hard drive?

    - by Corey
    I have a hard drive that is on its way out and won't boot to Windows 7. The Windows partition takes up the whole disk. I thought I would try to recover some recent files that hadn't been backed up. Assuming the files are recoverable, how can I explore the drive that has the corrupt sector and transfer files to a USB hard drive? If it helps, the laptop is able to see the USB drive when choosing a boot order. Some searching lead me to WinPE 3.0, part of the Windows Automated Install Kit. Is that a method?

  • How to Upgrade Your Netbook to Windows 7 Home Premium

    - by Matthew Guay
    Would you like more features and flash in Windows on your netbook?  Here’s how you can easily upgrade your netbook to Windows 7 Home Premium the easy way. Most new netbooks today ship with Windows 7 Starter, which is the cheapest edition of Windows 7.  It is fine for many computing tasks, and will run all your favorite programs great, but it lacks many customization, multimedia, and business features found in higher editions.  Here we’ll show you how you can quickly upgrade your netbook to more full-featured edition of Windows 7 using Windows Anytime Upgrade.  Also, if you want to upgrade your laptop or desktop to another edition of Windows 7, say Professional, you can follow these same steps to upgrade it, too. Please note: This is only for computers already running Windows 7.  If your netbook is running XP or Vista, you will have to run a traditional upgrade to install Windows 7. Upgrade Advisor First, let’s make sure your netbook can support the extra features, such as Aero Glass, in Windows 7 Home Premium.  Most modern netbooks that ship with Windows 7 Starter can run the advanced features in Windows 7 Home Premium, but let’s check just in case.  Download the Windows 7 Upgrade Advisor (link below), and install as normal. Once it’s installed, run it and click Start Check.   Make sure you’re connected to the internet before you run the check, or otherwise you may see this error message.  If you see it, click Ok and then connect to the internet and start the check again. It will now scan all of your programs and hardware to make sure they’re compatible with Windows 7.  Since you’re already running Windows 7 Starter, it will also tell you if your computer will support the features in other editions of Windows 7. After a few moments, the Upgrade Advisor will show you want it found.  Here we see that our netbook, a Samsung N150, can be upgraded to Windows 7 Home Premium, Professional, or Ultimate. We also see that we had one issue, but this was because a driver we had installed was not recognized.  Click “See all system requirements” to see what your netbook can do with the new edition. This shows you which of the requirements, including support for Windows Aero, your netbook meets.  Here our netbook supports Aero, so we’re ready to go upgrade. For more, check out our article on how to make sure your computer can run Windows 7 with Upgrade Advisor. Upgrade with Anytime Upgrade Now, we’re ready to upgrade our netbook to Windows 7 Home Premium.  Enter “Anytime Upgrade” in the Start menu search,and select Windows Anytime Upgrade. Windows Anytime Upgrade lets you upgrade using product key you already have or one you purchase during the upgrade process.  And, it installs without any downloads or Windows disks, so it works great even for netbooks without DVD drives. Anytime Upgrades are cheaper than a standard upgrade, and for a limited time, select retailers in the US are offering Anytime Upgrades to Windows 7 Home Premium for only $49.99 if purchased with a new netbook.  If you already have a netbook running Windows 7 Starter, you can either purchase an Anytime Upgrade package at a retail store or purchase a key online during the upgrade process for $79.95.  Or, if you have a standard Windows 7 product key (full or upgrade), you can use it in Anytime upgrade.  This is especially nice if you can purchase Windows 7 cheaper through your school, university, or office. Purchase an upgrade online To purchase an upgrade online, click “Go online to choose the edition of Windows 7 that’s best for you”.   Here you can see a comparison of the features of each edition of Windows 7.  Note that you can upgrade to either Home Premium, Professional, or Ultimate.  We chose home Premium because it has most of the features that home users want, including Media Center and Aero Glass effects.  Also note that the price of each upgrade is cheaper than the respective upgrade from Windows XP or Vista.  Click buy under the edition you want.   Enter your billing information, then your payment information.  Once you confirm your purchase, you will directly be taken to the Upgrade screen.  Make sure to save your receipt, as you will need the product key if you ever need to reinstall Windows on your computer. Upgrade with an existing product key If you purchased an Anytime Upgrade kit from a retailer, or already have a Full or Upgrade key for another edition of Windows 7, choose “Enter an upgrade key”. Enter your product key, and click Next.  If you purchased an Anytime Upgrade kit, the product key will be located on the inside of the case on a yellow sticker. The key will be verified as a valid key, and Anytime Upgrade will automatically choose the correct edition of Windows 7 based on your product key.  Click Next when this is finished. Continuing the Upgrade process Whether you entered a key or purchased a key online, the process is the same from here on.  Click “I accept” to accept the license agreement. Now, you’re ready to install your upgrade.  Make sure to save all open files and close any programs, and then click Upgrade. The upgrade only takes about 10 minutes in our experience but your mileage may vary.  Any available Microsoft updates, including ones for Office, Security Essentials, and other products, will be installed before the upgrade takes place. After a couple minutes, your computer will automatically reboot and finish the installation.  It will then reboot once more, and your computer will be ready to use!  Welcome to your new edition of Windows 7! Here’s a before and after shot of our desktop.  When you do an Anytime Upgrade, all of your programs, files, and settings will be just as they were before you upgraded.  The only change we noticed was that our pinned taskbar icons were slightly rearranged to the default order of Internet Explorer, Explorer, and Media Player.  Here’s a shot of our desktop before the upgrade.  Notice that all of our pinned programs and desktop icons are still there, as well as our taskbar customization (we are using small icons on the taskbar instead of the default large icons). Before, with the Windows 7 Starter background and the Aero Basic theme: And after, with Aero Glass and the more colorful default Windows 7 background.   All of the features of Windows 7 Home Premium are now ready to use.  The Aero theme was activate by default, but you can now customize your netbook theme, background, and more with the Personalization pane.  To open it, right-click on your desktop and select Personalize. You can also now use Windows Media Center, and can play-back DVD movies using an external drive. One of our favorite tools, the Snipping Tool, is also now available for easy screenshots and clips. Activating you new edition of Windows 7 You will still need to activate your new edition of Windows 7.  To do this right away, open the start menu, right-click on Computer, and select Properties.   Scroll to the bottom, and click “Activate Windows Now”. Make sure you’re connected to the internet, and then select “Activate Windows online now”. Activation may take a few minutes, depending on your internet connection speed. When it is done, the Activation wizard will let you know that Windows is activated and genuine.  Your upgrade is all finished! Conclusion Windows Anytime Upgrade makes it easy, and somewhat cheaper, to upgrade to another edition of Windows 7.  It’s useful for desktop and laptop owners who want to upgrade to Professional or Ultimate, but many more netbook owners will want to upgrade from Starter to Home Premium or another edition.  Links Download the Windows 7 Upgrade Advisor Windows Team Blog: Anytime Upgrade Special with new PC purchase Similar Articles Productive Geek Tips How To Upgrade from Vista to Windows 7 Home Premium EditionAnother Blog You Should Subscribe ToMysticgeek Blog: Turn Vista Home Premium Into Ultimate (Part 3) – Shadow CopyUpgrade Ubuntu from Breezy to DapperHow to Upgrade the Windows 7 RC to RTM (Final Release) TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips DVDFab 6 Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 Get Your Delicious Bookmarks In Firefox’s Awesome Bar Manage Photos Across Different Social Sites With Dropico Test Drive Windows 7 Online Download Wallpapers From National Geographic Site Spyware Blaster v4.3 Yes, it’s Patch Tuesday

  • Integrating WIF with WCF Data Services

    - by cibrax
    A time ago I discussed how a custom REST Starter kit interceptor could be used to parse a SAML token in the Http Authorization header and wrap that into a ClaimsPrincipal that the WCF services could use. The thing is that code was initially created for Geneva framework, so it got deprecated quickly. I recently needed that piece of code for one of projects where I am currently working on so I decided to update it for WIF. As this interceptor can be injected in any host for WCF REST services, also represents an excellent solution for integrating claim-based security into WCF Data Services (previously known as ADO.NET Data Services). The interceptor basically expects a SAML token in the Authorization header. If a token is found, it is parsed and a new ClaimsPrincipal is initialized and injected in the WCF authorization context. public class SamlAuthenticationInterceptor : RequestInterceptor {   SecurityTokenHandlerCollection handlers;   public SamlAuthenticationInterceptor()     : base(false)   {     this.handlers = FederatedAuthentication.ServiceConfiguration.SecurityTokenHandlers;   }   public override void ProcessRequest(ref RequestContext requestContext)   {     SecurityToken token = ExtractCredentials(requestContext.RequestMessage);     if (token != null)     {       ClaimsIdentityCollection claims = handlers.ValidateToken(token);       var principal = new ClaimsPrincipal(claims);       InitializeSecurityContext(requestContext.RequestMessage, principal);     }     else     {       DenyAccess(ref requestContext);     }   }   private void DenyAccess(ref RequestContext requestContext)   {     Message reply = Message.CreateMessage(MessageVersion.None, null);     HttpResponseMessageProperty responseProperty = new HttpResponseMessageProperty() { StatusCode = HttpStatusCode.Unauthorized };     responseProperty.Headers.Add("WWW-Authenticate",           String.Format("Basic realm=\"{0}\"", ""));     reply.Properties[HttpResponseMessageProperty.Name] = responseProperty;     requestContext.Reply(reply);     requestContext = null;   }   private SecurityToken ExtractCredentials(Message requestMessage)   {     HttpRequestMessageProperty request = (HttpRequestMessageProperty)  requestMessage.Properties[HttpRequestMessageProperty.Name];     string authHeader = request.Headers["Authorization"];     if (authHeader != null && authHeader.Contains("<saml"))     {       XmlTextReader xmlReader = new XmlTextReader(new StringReader(authHeader));       var col = SecurityTokenHandlerCollection.CreateDefaultSecurityTokenHandlerCollection();       SecurityToken token = col.ReadToken(xmlReader);                                        return token;     }     return null;   }   private void InitializeSecurityContext(Message request, IPrincipal principal)   {     List<IAuthorizationPolicy> policies = new List<IAuthorizationPolicy>();     policies.Add(new PrincipalAuthorizationPolicy(principal));     ServiceSecurityContext securityContext = new ServiceSecurityContext(policies.AsReadOnly());     if (request.Properties.Security != null)     {       request.Properties.Security.ServiceSecurityContext = securityContext;     }     else     {       request.Properties.Security = new SecurityMessageProperty() { ServiceSecurityContext = securityContext };      }    }    class PrincipalAuthorizationPolicy : IAuthorizationPolicy    {      string id = Guid.NewGuid().ToString();      IPrincipal user;      public PrincipalAuthorizationPolicy(IPrincipal user)      {        this.user = user;      }      public ClaimSet Issuer      {        get { return ClaimSet.System; }      }      public string Id      {        get { return this.id; }      }      public bool Evaluate(EvaluationContext evaluationContext, ref object state)      {        evaluationContext.AddClaimSet(this, new DefaultClaimSet(System.IdentityModel.Claims.Claim.CreateNameClaim(user.Identity.Name)));        evaluationContext.Properties["Identities"] = new List<IIdentity>(new IIdentity[] { user.Identity });        evaluationContext.Properties["Principal"] = user;        return true;      }    } A WCF Data Service, as any other WCF Service, contains a service host where this interceptor can be injected. The following code illustrates how that can be done in the “svc” file. <%@ ServiceHost Language="C#" Debug="true" Service="ContactsDataService"                 Factory="AppServiceHostFactory" %> using System; using System.ServiceModel; using System.ServiceModel.Activation; using Microsoft.ServiceModel.Web; class AppServiceHostFactory : ServiceHostFactory {    protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)   {     WebServiceHost2 result = new WebServiceHost2(serviceType, true, baseAddresses);     result.Interceptors.Add(new SamlAuthenticationInterceptor());                 return result;   } } WCF Data Services includes an specific WCF host of out the box (DataServiceHost). However, the service is not affected at all if you replace it with a custom one as I am doing in the code above (WebServiceHost2 is part of the REST Starter kit). Finally, the client application needs to pass the SAML token somehow to the data service. In case you are using any Http client library for consuming the data service, that’s easy to do, you only need to include the SAML token as part of the “Authorization” header. If you are using the auto-generated data service proxy, a little piece of code is needed to inject a SAML token into the DataServiceContext instance. That class provides an event “SendingRequest” that any client application can leverage to include custom code that modified the Http request before it is sent to the service. So, you can easily create an extension method for the DataServiceContext that negotiates the SAML token with an existing STS, and adds that token as part of the “Authorization” header. public static class DataServiceContextExtensions {        public static void ConfigureFederatedCredentials(this DataServiceContext context, string baseStsAddress, string realm)   {     string address = string.Format(STSAddressFormat, baseStsAddress, realm);                  string token = NegotiateSecurityToken(address);     context.SendingRequest += (source, args) =>     {       args.RequestHeaders.Add("Authorization", token);     };   } private string NegotiateSecurityToken(string address) { } } I left the NegociateSecurityToken method empty for this extension as it depends pretty much on how you are negotiating tokens from an existing STS. In case you want to end-to-end REST solution that involves an Http endpoint for the STS, you should definitely take a look at the Thinktecture starter STS project in codeplex.
