hi Web gurusI am a c++ developer and unfortunately I have to code a small web app in which I aint got no choice to choose what tools to use. I have never worked on a web based application development. I have been asked to use Asp.net mvc 1.0 in .net 3.5 (no mvc2.0 or .net 4.0 framework) using c# and jsonthe controller sends and receives json and the client side is not a web app.. it can be a smart phone app or a desktop appI have completed some of the coding which I can send a json object to the client (contenttype :application/json  for example        public class person        {            public string name { get; set; }            public string postcode { get; set; }        }        public JsonResult test()        {            person p = new person();            p.name = "your name";            p.postcode = "your post code";            return Json(p);&nb

C# and the Web: Writing a Web Client Application with Managed Code in the Microsoft .NET Framework

  

When the author wanted to build a middleware Web client to connect to other applications over the Internet, he realized that the XMLHttpRequest COM object was not sufficient for his purposes. In order to build a Web client using managed code, the author had to use the HTTPWebRequest and HTTPWebResponse classes provided by the Microsoft .NET framework. These classes are used in the sample project as a substitute for the less powerful XMLHttpRequest COM object, allowing the author to build a full-featured Web client. They also take advantage of all the benefits that the CLR and managed code have to offer.

Web Security: Part 2: Introducing the Web Application Manager, Client Authentication Options, and Pr

  

This article, the second of two parts, continues coverage of Web security for Windows. It introduces the Web Application Manager in IIS that allows Web processes to be isolated, decreasing the security risk associated with running in a logon session. The article then picks up where Part One left off-it discusses authentication methods such as basic authentication, digest authentication, integrated Windows authentication, and anonymous logons, and the benefits and drawbacks of each.

WCF Membership Authentication and Winform Client Application Services

  
I am needing more validation of what I am doing versus solving a problem. I have a winforms application that uses Client Application Services to validate a user against a customer membership provider all over SSL.  This works fine.  My winforms application validates correctly. The winforms application uses WCF to call services that are installed on the same IIS server that is providing the membership services for the Client Application Services.  The WCF services use wsHTTP binding, transport security, username credentials, and validate against the same membership provider as the Client Application Services. It appears that although the service and Client Application Services are at the same URL, they do not share credentials between them.  Ideally, once I log into Client Application Services, any calls to a WCF service at that location would be automatically authenticated.  However, this is not true.  I have to pass the username and password into the credentials for the WCF service.  This works as expected where the username and password are validated prior to allowing a service call.  On subsequent services calls, it does not validate again since it has established the secure channel. So, does this sound like the best approach?  Is there a way to pass credentials from the Client Application Services to WCF automatically?  I

Client Application Services - Role service cache time out bug

  
Hi All, For people using Client Application Services with WPF, be aware of this bug. You can configure the "cache time out" for roles to be fetched again from the service. (In the visual studio dialog, Properties -> Services -> Advanced) This means the roles are cached on the client (in a file). If the application asks for roles again, they are not fetched again for "cache time out" time. When you set this value, it goes into your App.config, transformed into seconds. So if you choose 1 minute, the App.config has: cacheTimeout="60".   However, when using the ClientRoleProvider (for instance to do something like clientRoleProvider.GetRolesForUser("SomeUser")), this cacheTimeOut is interpreted in Minutes, not seconds! To prove my point, check ClientRoleProvider.Initialize method:   string temp = config["cacheTimeout"]; if (!string.IsNullOrEmpty(temp)) _CacheTimeout = int.Parse(temp, CultureInfo.InvariantCulture);   Later on, in ClientRoleProvider.GetRolesFromDBUser (what's in a name?), you see: _CacheExpiryDate = cd.RolesCachedDateUtc.AddMinutes(_CacheTimeout);   Testing also shows this behavior. So be aware, and always put the value in minutes in your App.Config!   Regards, Koen

Client Application Services and Man-in-the-Middle

  
Backgorund: I am using Client Application Services with a WPF client. The client talks to a Forms authenticated web site. I am using the Forms token to protect web services that the client uses to get information from the web site. I am protecting the web services with certificates, both server and client. Issue: All the web services are protected against man-in-the-middle attacks. The test I am using is to load Fiddler on the client and allow it to install certificates. The presence of fiddler as man-in-the-middle is detected by all the web services but not by the validation request of Client Application Services. I am able to read the user name and password from that message using Fiddler. How can I get client application services to use the certificates?
