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 RepliesThe client wants to see a graphical representation of the workflow. In addition (let's say it is a workflow for processing orders), the client wants to see at what point in the workflow any given order is, indicated on the graphical workflow representation by a highlighted node or some visual queue.
All of this must be available via a web interface.
Was hoping somebody had some bright ideas for how to achieve this without writing extensive custom controls.
Does Workflow Foundation 4 offer anything itself that would assist toward this end?
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 been, exhaustively, looking at examples of WF4 and am not sure it will work for my project. I need to be convinced otherwise. I am struggling with how we would implement a system to use WF4 so users have the ability to define workflows. It seems you need VS2010 experience to design and implement a WF 4workflow. I love wheat it can offer, but feel it may be too complicated for non techical users.
Do we just define a ton of custom activies that a user can move into a workflow? How can we make it as easy as possible for a user to build the workflow?
We have and application that we want to allow, Joe / Jane user to create their own workflows for specific items. For example, Request For Information items. The RFI has specific states it can be in that are defined by the user.
They should be allowed to control the flow based on those states. There will be some base items that the application defines as to what will happen based on a decision / condition. So, things like notifications (who gets notified when something changes), time frames (how long something can stay in a certain state before something else happens), and possibly some other conditions.
The conditions / decision types will be limited by the application, for now. But imagine they can build the workflow and add those decisions / conditions in without any coding knowledge.
Can Windows Service work on shared hosting?
View 1 RepliesI 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 ?

View 1 RepliesI 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 understand the concepts of windows workflow...But unable to understand how to implement it...Can anyone tell me some good sites which explains Workflow with coding???
View 1 RepliesOur 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?

I have a web service that has a CreateReport method that generates a report based on the specified criteria.
When I call this method Synchronously using a Windows Application or Console Application, the call works fine and the report is created.
When I call this method ASynchronously (CreateReportASync) using Windows Application the report is created.
When I call this method ASynchronously (CreateReportASync) using Console Application the web service does not even get the call.
I am using VS2005 and .Net Framework 2.0. So the proxy is automatically created with the Async methods. I am not really interested the result of the method call, so I do not add a Callback Delegate.
I have a really weird problem that I've been investigating for at least one week now. I deliver a website hosting both ASP classic and .NET 3.5 content in IIS6 on a Windows 2003 server environment with MySQL db backend. The solution has been installed on several servers (some hosted in WMWare) with no problems. On one specific server, also hosted in WMWare, the user experience great performance issues on the website. The problems are most seen when using database resources and is not limited to either .net or asp classic, but I am still not sure that the problem is only related to database calls.
Following components are involved:
IIS6 .NET FW 3.5 MyODBC 3.51 / 5.1 MySQL 4.x
Code executed on the server using all resources above runs smoothly when the IIS is not involved. The website shows times up to 2 minutes to execute code that takes 2 seconds outside the IIS. The exact same code is executed. Using profiling tools, I've seen that the great loss comes within calls to unmanaged code, for example when System.Data.ODBC namespace to calls into myodbc.dll.
The tricky part is: If at least one console user is logged in to the server, the performace problems are not seen anymore. When the user logs out, the problem appears again.I have tried to reinstall all components above, tried different versions of MyODBC, tried different website authentication methods, tried to run website under administrator privilegies, installed various MS KB's with no success.

View 3 RepliesI have a Wordpress blog on GoDaddy. I originally had it using "Windows Hosting" but ran into problems so moved it to "Linux Hosting" since I was told it was more compatible and there would be fewer issues. I had a 3rd party customize the blog and add some code, etc. I would like now to use WebMatrix to continue customizing the blog on my own, and be able to step through code and add php etc. So my questions are these. Will Webmatrix work in this scenario --- Linux Hosting and processing PHP? Or do I have to move my blog onto Windows Hosting so that it uses IIS? And second...what would I have to do...FTP down my wordpress files as well as my database in order to use Webmatrix?
