I wonder if there are some differences between creating a WCF service and an MVC web-application. If you know of good links on how to create such a service for an MVC application that returns a JSON object please do post them.
View 1 RepliesI am trying dynamically to create an .ics file when ever a user clicks on a attend button in an asp.net application . But it is throwing an runtime error. if we dont have any controllers except other than a single button control , we were able to generate the .ics file, but a full fledged aspx page which in turn is associated with an master page . we are getting errors.can some one let us know if there is an alternative solution for these kind of issues.
View 4 RepliesI need to read the data from the COM port in a web application, so I have written a Windows Service for reading data from serial ports. Now I need to access that data in a web application. Can anyone tell me how to access it? Is using threads the best way to do this or not? What other possible ways are there?
View 3 RepliesI have an ASP.NET Web Forms Application in migration process to ASP.NET MVC 1. Urls are as follows:
[URL]
(hxxp because stackoverflow thinks they are links and prevents me from posting so many)
"mvc" is another application inside my Web Site in IIS7.
I now need to be able to do this:
[URL]
Where 'subsiteName' can be anything and must be checked in runtime. I can't create directories for each subsiteName.
I thought of UrlRewriting, so /subsiteName/* rewrites to /*, but then I'd have to rewrite from WebForms to MVC.
I can't imagine a way to make a request to [URL]ever be taken by the MVC application in this scenario.
In Visual Studio 2005.I have created a Blank solutions(XYZ) and then add a ASP.Net Web Service Project(TESTP) under it.And then create a .asmx file(WEBFI.asmx) and then write a method and add [WEB Method] on top of the method.Now compile it.And then publish it.But in publishing folder I didn’t found any WSDL file which I should call in different machine (which is in LAN ).
View 6 RepliesI wounder if there are some differencences when creating a wcf serivce to a MVC webbapplication.
how to create such a serivce for a MVC application. and returns a json object.
I've looked around for some tutorials, but everything I see is how to use REST services with my app. But that's not really what I need, I'm not doing basic GET requests, the end user needs to do some complicated calculations with several classes and variables from my web service.
In a Web Forms app, I would just add a Web Services solution and do everything in there. Is that the recommended solution for an MVC app?
I am trying to create an msi for a Web Service. I want the web service to be installed as a 'Web Site' not as an 'Application' under Default Web Site in IIS. I have code that creates a web site, but when I try to add it as a custom action under the install node of the msi, the code isn't getting executed. Reading about installers, it seems that anything under the install node gets fired after the installer has already started, if that makes sense. I want to be able to create the web site before the installer actually begins the installation process so that when the user comes to the window where he/she has to choose the Site under which to install the web service it can already be listed there and they'll be able to choose it.
View 1 RepliesI am trying to create a web service application that will need to use .net 4.0 for my datamodeling and other things. I noticed in VS2010 when I select New | Project the "ASP web service app" option is available if .net 3.5 is selected in the combo box but if I change that to .net 4.0 the option goes away.
After researching the only thing I found was a message where someone suggested to use the WCF web service option. I have never dealt with WCF before so I have no idea what path that will lead me down.
Here is my concern... we have existing web services developed in .net 3.5 that are already in use and we have windows based client applications that are developed in Delphi (version 7.0 to be specific) that already talk to these web services with no problems and no special coding required. Delphi can simply import the WSDL which generates an interface unit that gets compiled in and away we go. This new service app I need to create must also be accessed via the same Delphi apps.
The current asp web service apps generate 4 files when "published": web.config, .asmx file and in a in folder there is a .pdb and .dll file.
Can anyone tell me if support for this type of web service app is still available via .net 4.0 and if so how do I create the project or is that something that has been discontinued and thus no longer possible?

I am creating new WCF service and i would like to do two way XML for communicating with third party vendors. My wcf service get the request from the outside program by means of URL and it should response accordingly.
Example - I have url which third party will call and put xml as a request, i have to get that xml, work accordingly and response back with either success or failure and appropriate xml. I need to make it completely automatic so anybody can call that url, it will validate that user and do the next step of request and response.
i am in the process of creating a restful service with WCF, the service is likely to be consumed by at least 500 people at any given time. What settings would i need to set in order to deal with this.

We are consuming third Web services.
Instead of using datatypes from web service proxy we need to create our own class which will take the values from web service output.

View 1 RepliesMy instructions for creating a new web service with VWD 2010 Express call for using the installed template, "AST.NET Web Service". But this template is not listed.
I would like to create a simple web service in visual basic, place it in IIS 7 on my desktop, and then consume it probably using a proxy class.
Is there another way to create a new web service in VWD 2010 Express?
is it possible to create web service and asp.net application in a single solution and deploy
