I am beginner in the Windows Communication Foundation. I am reading about it. I am little bit confused with the word 'Windows'. WCF can be used for building the web services for window application as well as web application. Then what is meaning of the word 'Windows' in WCF ? Why we are calling it as a 'Windows' Communication foundation ?

When i create a Windows Service for getting information from a Web Application(ASP.NET c#) for scheduling some task in the client machine.
To consume WCF from the web application. I added WCF reference to Window Service project as a service reference, everything seems fine. It updated app.config file, added service reference etc.
it was not working.

I Need by service contract to return the xml/json result depending on the request type. function which will convert my result set (i am using linq to sql) so that i do not need to create the xml format for the result set by iterating through the table row many times.What is the suitable way to do that.
I need a kind of short cut method which will convert the table data to xml result.Had i been using asp.net mvc i would have been able to generate the xml data by overriding the the ExecuteResult method in the ActionResult and giving Conetnt-Type = "text/xml" as OP.But since i am using Wcf i don't have the controller context(as controller context is the parameter that needs to be passed to Execute Result).
My present code for converting the table data to the xml format is below.
public XDocument UsersLists(string authToken)
{
bool IsAuthenticated = Authenticate(authToken);
XDocument xDoc = new XDocument();
XElement root = new XElement("Users");
[Code]....
I need to eliminate this way of generating xml for each table records.
I have an requirement to implement single sign on solution using SAML 2. I had a look at a tirdparty toolkit in componentspace, but I would prefer some microsoft components.
the features provided in componentspace toolkit can be done using some Microsoft .NET libraries itself. identify the microsoft way to do this?. I looked at the Windows Identity Foundation SDK, but it is now supported only for .NET 3.5. My web application is built on .NET 2.0.
Is there any alternative for Windows Identity Foundation in .NET framework 2.0?
I'm writing an ASP.net application that uses Windows Identity Foundation. My ASP.net application uses claims-based authentication with passive redirection to a security token service. This means that when a user accesses the application, they are automatically redirected to the Security Token Service where they receive a security token which identifies them to the application.
In ASP.net, security tokens are stored as cookies.
I want to have something the user can click on in my application that will delete the cookie and redirect them to the Security Token Service to get a new token. In short, make it easy to log out and log in as another user. I try to delete the token-containing cookie in code, but it persists somehow.
How do I remove the token so that the user can log in again and get a new token?
I read some blog that If we host workflow foundation in asp.net, there will be issues with workflow persistence, is this correct? and what is the better idea to host workflow foundation on asp.net or on windows service?
View 1 RepliesI am create an iPhone app that needs to talk to a Windows C# app. The app will run as either a Service or Form Application.
What would be the best way to accomplish this? Ideally exposing a service-type architecture would be best as I don't need a stateful connection (stateless is fine in this case).
Can a WCF service hosted by my app using a form of TCP binding be consumed by my iPhone? Or can an app host using httpBinding without the aid of IIS or some other web server?
Our solutions requires validating users against a custom database. This also includes roles which dictates what he user can do in the system. What is the best way to implement implement security, is it to use Windows Identity Foundation or the default Membership Provider and Role Provider that comes with .net?
View 2 RepliesI've been trying to set a STS project in my solution following these steps on Channel 9. Right after hitting "Finish", I get an exception saying: The system cannot find the file specified. (Exception from HRESULT: 0x80070002).

My OS is Windows 7 Enterprise x64, both Visual Studio 2010 and Visual Web Developer 2010 Express are installed in my machine, the WIF SDK 4, the runtime 6.1 and the Identity Training Kit from January 2011.
What are the different ways in which a web application can communicate to a windows application? I have heard that activex control events can be handled in javascript to achieve this.
Does WCF or any new technology provide a better implementation for this?
Can the publish/subscribe architecture be used here?
Microsoft Visual Studio 2010 was being used along with SQL Express for website development on the Operating System, Windows Server 2008 R2 Enterprise Edition of Intel Xeon CPU @ 2.13 GHz (2 Processors) containing 12 GB RAM with 64-bit Operating System.

View 1 RepliesI have been trying to avoid the windows login userid and password window when I use the Windows Authentication mode for a web site. I need to capture the the windows logon user name without prompting for the user id and password and display that on the web site. I had tried almost everything... changed authentication,security setups on IE and IIS etc... still not being able to avoid the window...
View 1 RepliesI'm trying to enable automatic Window authentication working on our ASP.NET Intranet. I've changed the Authentication on our IIS 7.5 server from Anonymous to Windows Authentication Enabled only, and changed the Web.config file for the website to:
<authentication mode="Windows" />
<authorization>
<deny users="?" />
</authorization>
The Windows login box appears when accessing the website via IE 8, I enter valid credentials, but the login window keeps reappearing as if it does not accept my credentials. By repeatedly cancelling the login box it disappears, and my login name can be viewed on the website. Is there any possible reason for the login box to keep popping up even though valid credentials are being entered? I've restarted the servers / cleared browser cache etc. Also, ideally I would like the user to enter the login details once in the login box and not be required to reenter login details whenever he reopens the browser.
I've installed IIS for Windows Server 2008 SP2 and Windows 7. In both instances, I can't get even the simplest of ASP.net scripts to work (note: I'm ftping the published files from Visual Web Dev 2008 Express on XP):

I have three windows:
1st - main window
2nd - child window - it's opened using window.showModalDialog from 1st widnow.
3rd - window - is an ancestor of 1st window and is's opened from 2nd window using window.showModalDialog.
And now what I need to achieve is to open 1, 2 and 3 window. Next after closing the 3rd one, refresh the 2nd one. And after closing the 2nd one, refresh the 1st one.
But there is one more assumption, I don't want to have any post-back during this process.
I just downloaded and installled the Microsoft Windows Azure SDK yesterday for the first time and I am having issues running the application as I all I am getting is 503 errors. I run Windows Server 2008 R2 on my development machine and even tested it on another co-workers 2008 R2 and couldn't even compile the application. He got this error instead "A problem occurred while trying to set the "References" parameter for the IDE's in-process compiler. Error HRESULT E_FAIL has been returned from a call to a COM component."
From within my Windows Server 2008 R2 Hyper-V Virtual Windows 7 x86 enviroment, I was able to successfully build and run the Windows Azure SDK and it even showed the base ASP.NET application.So my question is, does the Windows Azure SDK for Visual Studio 2010 w/ Visual Studio 2010 SP 1 installed not work under Microsoft Server 2008 R2?
We have a working version of application (Intranet) with uses Windows Authentication deployed in Windows 2003. The application uses HttpContext.Current.User.Identity.Name to get the logged-in user. Here impersonate is turned off.Right now, we are move to Windows 2008 RC2 where this Windows Authentication problem arised. I have Digest Authentication and Windows Authentication enabled. And also I have enabled Anonymous Authentication enabled to avoid the Login dialog of IIS in the end-user IE. Now I am getting HttpContext.Current.User.Identity.Name as Empty. When I impersonate using username and password, I am used to login using that user but all the users uses the same user to login.Does any has solution for this?Deployment Server - Windows 2008 RC2 (IIS 7.5)Development - Windows 7 (IIS 7.5)I am new to IIS 7.5. Please give me a solution
View 3 RepliesMy overall goal is just to get the logged on users information for an Intranet site I'm developing without them providing their login (since they are already logged into their computer). So far I just get 401.1 errors and it keeps asking for my login/password. Even though I provide my login/password, it still won't let me in.
I've Enabled Windows Authentication from IIS > Sites > Default Web Site, added this to my web.config:

We have a website portal hosted in Windows 2003 server. For security reasons we are using different windows Login user say (xxxx) for signin other than Administrator. Now with this user (xxxx) name I installed .net Windows Application. It was working fine. For some reasons I renamed the original windows Login user(xxxx) to different say (yyyy). Now this .net Windows Application is not working with (yyyy) and even it is not allowing me to uninstall it.
View 3 RepliesWhen I am working on projects I like to take my files back and forth between two machines.The machine at my office is running Windows XP Pro 32-bit.My home pc is brand new and running Windows 7 64-bit.I have not yet installed Visual Studio 2008 on the new home pc.My projects usually consist of a web site in ASP.net and C# often with a SQL Server 2008 Express Edition database backend.I am using Visual Studio 2008 Standard Edition (yes, I know I need to upgrade soon).
Before I received the new computer I was simply copying what I did at one machine onto a USB drive, taking it the other machine and overwriting the files that were previously there. Is it feasible to continue moving project files back and forth between computers now that one machine is running a 32-bit OS and one is running a 64-bit OS?
I'm running windows 7, so I installed on my machine the oracle client version 11.1.0.7.0 (ODP.NET - Oracle.DataAccess version 2.111.7.20) .
I'm trying to deploy an asp.net web application to a server that is running windows 2003, which has the oracle client version 11.1.0.6.0 (ODP.NET - Oracle.DataAccess Version 2.111.6.20)
In my web.config file I have:
<add assembly="Oracle.DataAccess, Version=2.111.6.20, Culture=neutral, PublicKeyToken=89B483F429C47342"/>
(which for my surprise it compiles just fine).
Now when I compile my application and deploy it in a setup project (as pre-compiled). The start page of my web app tires to connect to Oracle and it returns the following error message:
"Could not load file or assembly 'Oracle.DataAccess, Version=2.111.7.20, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified."
Which is super weird because, cause the web.config file as shown above has Version=2.111.6.20.
Now the strange part is that if I copy the source code from the client to the server, the same code, same config file, it works just fine.
So I'm thinking that the pre-compiled version is telling the server to load Oracle.DataAccess Version=2.111.7.20, maybe in one of the dlls, not in the config file for sure.
Has anyone run into this problem?
what's the best approach to deploy to servers with different oracle client version? (I have a similar problem trying to deploy to a 64 bit machine)
I am developing one intranet website. Being an intranet application, one of the requirement is to have a single sign on feature.
It means that the windows PC username (i.e the "ctrl + alt + delete" username) is going to be the username for the system.
How do i fetch that username?
I tried the following two ways which are working in debug mode but not on live site.
System.Security.Principal.IPrincipal user = System.Web.HttpContext.Current.User;
Response.Write(user.Identity.Name);
&
Response.Write(Request.ServerVariables["AUTH_USER"].ToString());
Both the above method works when i run the page from visual studio.
However when i run the page from IIS or any other server, it gives me a blank value
