1. Get the Linux Integration Services 2.1 Beta from https://connect.microsoft.com/site495
2. Extract the files and insert the .iso as a disk in your virtual machine
3. Now the hard/long part, update your Kernel with version 2.6.27.47 (This is out of scope, so you will have to look for info on how to do this).
4. Reboot and choose your new Kernel
5. #mount /cdrom
6. #mkdir /opt/linux_ic_v21_rc
7. #cp /cdrom/* /opt/linux_ic_v21_rc -R
8. #mkdir /etc/sysconfig/network
9. # cd /opt/linux_ic_v21_rc  -R
10. Modify the Mafile file replacing all the occurrences of —reload-rules with —reload_rules
11. Modify the scripts/updateinitrd.pl file commenting lines 79 to 87 and adding this line after that $initrdfile = “/boot/initrd.img-2.6.27.47″;  
12. Modify scripts/updategrub.pl file replacing line 55 with $grubfile = “/boot/grub/menu.lst”;
13. #apt-get install chkconfig
14. #make
15. #make install
16. Modify your /etc/init.d/vmbus file commenting lines 55 to 61 and 108 to 112. Also replace line 73 with return 0 and 75 with return 1
17. Modify your /etc/network/interfaces file replacing eth0 with seth0
18. Modify your /etc/initramfs-tools/modules file adding a vmbus line and a netvsc line
19. #update-initramfs –u –k 2.6.27.47
20. Shutdown your virtual machine #init 0
21. Replace your legacy network adapter with a normal Network adapter copying your old adapter’s MAC to your new adapter
22. Start your virtual machine
23. That’s it, now you have a Debian Hyper-V virtual machine with Integration Services.

public class ServiceHostFactory : WebServiceHostFactory
    {
        protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
        {
            ServiceHost host = new ServiceHost(typeof(Services), baseAddresses);
            host.Authorization.PrincipalPermissionMode = PrincipalPermissionMode.None;
            ServiceEndpoint endpoint = host.AddServiceEndpoint(typeof(IServices), new WebHttpBinding(WebHttpSecurityMode.Transport), "");
            endpoint.Behaviors.Add(new WebHttpBehaviorEx());
            return host;
        }
    }

This simple jquery code shows how to do it in the client side:

$.ajax({
    type: "POST",
    url: serviceURL,
    data: "data",
    success: function(data, textStatus) { alert("success"); },
    error: function(xhr, status, error) { alert("error"); },
    beforeSend: function(xhr) { xhr.setRequestHeader("X-HTTP-Method-Override", "DELETE"); }
});

This C# code shows how to use the custom header in a WCF server:

public String PostProxy(String data)
{
    switch (HttpContext.Current.Request.Headers["X-HTTP-Method-Override"])
    {
        case "PUT": return Add(data);
        case "DELETE": return Delete(data);
        default: return Update(data);
    }
}

<system.web>
    <httpRuntime maxRequestLength="131072" />
</system.web>

Note: this should work for any ASP application.

<location path="services">
    <system.web>
        <authorization>
            <allow users="*" />
        </authorization>
    </system.web>
</location>

Add this line of code to your service constructor method:

public Service()
{
    Thread.CurrentPrincipal = HttpContext.Current.User;
}

Finally use declarative permissions on the service methods you want to protect:

[PrincipalPermission(SecurityAction.Demand)]
public String YourMethod()
{
    return String.Empty;
}

public class MembershipProvider : System.Web.Security.SqlMembershipProvider
{
    const String UPPER = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    const String LOWER = "abcdefghijklmnopqrstuvwxyz";
    const String NUMBERS = "1234567890";
    const String SPECIAL = "*$-+?&=!%/";

    public override string GeneratePassword()
    {
        Random rand = new Random();
        String password = "";
        List<String> data = new List<String>();
        for (int i = 0; i < 10; i++)
        {
            if ( i < 3 ) data.Add(UPPER[rand.Next(UPPER.Length)].ToString());
            else if ( i < 6 ) data.Add(LOWER[rand.Next(LOWER.Length)].ToString());
            else if ( i < 8 ) data.Add(NUMBERS[rand.Next(NUMBERS.Length)].ToString());
            else if ( i < 10 ) data.Add(SPECIAL[rand.Next(SPECIAL.Length)].ToString());
        }
        while (data.Count > 0)
        {
            int pos = rand.Next(data.Count);
            password += data[pos];
            data.RemoveAt(pos);
        }
        return password;
    }
}

Note: After you do this you will not be able to use the IIS7 management for your users.

You can download the source code for this post here.

First we need to write a Class that mimics Status FQL table.

public class Status
{
    public String status_id { get; set; }
    public String time { get; set; }
    public String source { get; set; }
    public String message { get; set; }
}

Then we create a method to generate our data signature.

public static String GetSignature(Dictionary<String, String> parameters)
{
    MD5 md5 = MD5.Create();
    String data = "";
    String[] keys = parameters.Keys.OrderBy(k => k.ToString()).ToArray();
    for (int i = 0; i < keys.Length; i++)
    {
        String key = keys[i];
        String value = parameters[key];
        data += key + "=" + value;
    }
    data += "APPLICATION_SECRET";
    byte[] bytes = md5.ComputeHash(Encoding.UTF8.GetBytes(data));
    String signature = "";
    foreach (byte b in bytes) signature += b.ToString("x2");
    return signature;
}

After that we just build our post data, post our request, read our response and deserialize the status objects.

static void Main(string[] args)
{
    Dictionary<String, String> parameters = new Dictionary<String, String>();
    parameters.Add("format", "json");
    parameters.Add("method", "Fql.query");
    parameters.Add("query", "select status_id, time, source, message from status where uid = USER_ID");
    parameters.Add("session_key", "SESSION_KEY");
    parameters.Add("api_key", "API_KEY");
    parameters.Add("v", "1.0");
    parameters.Add("call_id", DateTime.Now.Ticks.ToString());
    parameters.Add("sig", GetSignature(parameters));
    String postData = "";
    for (int i = 0; i < parameters.Keys.Count; i++)
    {
        String key = parameters.Keys.ElementAt(i);
        String value = parameters[key];
        String param = key + "=" + HttpUtility.UrlEncode(value);
        postData += param;
        if (i < parameters.Keys.Count - 1) postData += "&";
    }
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://api.facebook.com/restserver.php");
    request.Method = "POST";
    request.ContentType = "application/x-www-form-urlencoded";
    StreamWriter writer = new StreamWriter(request.GetRequestStream());
    writer.Write(postData);
    writer.Close();
    DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(Status[]));
    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    Status[] statuses = (Status[])serializer.ReadObject(response.GetResponseStream());
    foreach (Status s in statuses)
    {
        DateTime time = new DateTime(long.Parse(s.time));
        Console.WriteLine(time.ToString() + ", " + s.message);
    }
    Console.ReadLine();
}

Note that you can use this approach to call any method in the RESTful API, not to just make FQL queries.
