Creating/Exposing WCF Services From An Existing Application?
Feb 24, 2011
We need to expose some services (i.e. AddressValidatorService, CustomerFinderService) that currently reside in an ASP.NET application to other applications within our organization. Exposing these services via WCF seems like a natural fit, but I don't see any best-practices for how to pull these common services into a WCF wrapper in such a way that my existing ASP.NET application can continue to use them with minimal code changes and/or awareness that the service they are consuming is no longer in-process. I'm especially looking for recommendations on how to structure the existing ASP.NET solution and whether to host our new WCF in the same solution or in some new shared WCF solution referenced by both our ASP.NET application and external callers.Also, is it bad practice to simply promote the DTOs currently only consumed in-process via ASP.NET to full fledged data contracts or is it preferable to create duplicate DTOs that are explicitly decorated with [DataContract]?
Is there any framework or tool to generate web services (WCF) access to all the non transactional tables in my database? something like asp.net dynamic data but with web services, I need to do this for homologation with other systems.
I have a class with about 5-10 methods which all my services (WCF) need to expose. What is the best way to expose all the methods in all the services keeping (DRY principle) in mind?Is interface inheritence a good design principle? e.g. public interface IBMW : ICar
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 want to format my numbers throughout the application in a consistent way, no matter what culture is chosen. In fact, it's "non-standard" even for the basic culture that we're using.
I want to format "{1500.50:c}" as: '1500.50', but the standard for my culture 'nl-NL', is: '€ 1.500,00'. We don't have the user-rights, since it's a webapplication, to register custom cultures, therefore we're looking for a runtime solution.
We want a "set and forget" solution. Not a Util class with static (extension) methods, but an application wide solution, so we can continue to use the standard .ToString("c"), or ToString("N") logic, which would follow our custom rules. This would be to alter the .NumberFormat of the Culture, but how? Everything seems to be readonly.
I have an existing web application developed in Asp.Net F/W 3.5 and a mobile version of the same need to be created.
May i have some suggestions on:
How can i start with?.Some links & sites that would give me more clarity on how to approach this requirement. Is there any ASP.Net/iis features or Visual Studio option that ease this mobile version creation? As there are RadControls & Ajax used throughout the application, what should i be careful about? Will it require every form in the UI to be replaced and take the same time as the old UI creation? What all thinks should i be considering in the performance/optimization point of view?.
I have an existing SQL database containing student:class enrollments and would like to add a login feature using asp.net's built in Membership and Roles management tools. to how to integrate the Application Services Database with an existing SQL database? Once I have created the Application Services tables using aspnet_regsql tool how and where do I create a link between my tables and the .Net Membership tables?
i am new to ASP.NET. I am just now learning about all the benefits. I currently have some C# code that receives sensor signals such as distances from a robot and I wish to put that code into web services and into a website, so that if I want to gather some information from the robot i can through the web, as well as send signals back. I haven't found any information yet on how to do this.
I am just looking on how to intergrate the existing C# code I have to a web service
I am using the ASP membership services to create and manage users. I notice that on user account registration everything works fine... Until I call Roles.AddUserToRole, and suddenly I get a second user account created in the aspnet_users table. I am quite certain that I should only ever have one user account in the database per registered user...
Apologies if this seems obvious, but after a week searching I can't find a clear answer to my problem.
I have developed an application in Visual Web Developer 2010 Express that uses the asp.net application services membership provider. It works well in development on my machine (data in the ASPNETDB.MDF database).
I packaged my application and deployed the relevant files with FTP to my shared hosting provider.
I took a copy of the ASPNETDB.MDF and restored it to the SQL Server 2008 on my shared hosting. I can connect to this through the Database Explorer in Visual Web Developer, but it doesn't contain any schema or data.
I know once I have the database in production I will have to make sure the connection string in web.config is poiting to it, but I don't know how to get the DB to production in the first place.
I want to add WCF to existing asp.net application and host both of them in the same virtual directory is it possible ?? Also when i click new item to add app.config file from visual studio its not showing.
This seems like a very basic question but I couldn't find any help on web. If you could provide some link or steps to do this.I have created few basic Silverlight applications which are working fine standalone. I also have a basic ASP.NET application with a solution with around 10 Class Library Projects and 1 website. I want to create a small popup which will have some funtionality using Silverlight.How should I go about creating this application and how to integrate it with my existing application for it to show as a link. I would not want that link to open another application/site.
Currently, on our production IIS web farm, we host about 15 applications in a single App Pool (Default App Pool). There are two websites and about 13 virtual directories.A colleague has recommended that we change our IIS configuration so each application is a separate App Pool (with identical settings).
Is there any drawback or potential issues to doing this?Is it possible that ASP.NET applications could have been built with the requirements that they are all within the same App Pool?
Is it possible to set up ASP.NET application services (membership, profiles, roles etc) for a site without having to run the aspnet_regsql tool directly?
I have managed to create the admin user and roles in session start for the first user that visits the site (the developer), but want to go an extra step before hand and create the tables if they don't exist.
The ultimate idea would be just for the DBA to create a blank database on the server and have the web application itself create all the required tables (if they don't exist).
What I am trying to do is install an open source application to my existing asp.net website. Within my solution in VS2008, I have two "Web Sites", one for my web site and one for the application (forums).I have my web site published to the main domain, and the forums web site published to a subdomain. They both work great.The problem I am having is that I cannot get them to communicate to each other, for example they can't access each others resources. They each have a separate membership provider, but I am attempting to combine them so that if the user logs into one, they are logged into the other. The reason that I have these as two separate web sites within one project is so that the forums can be hosted at the subdomain and the site would just be the main domain.My question is, would it even be possible to accomplish what I am trying to do using separate domains, and if so what would be the best approach?
We have a web application written in ASP.NET for .NET 3.5, using standard web forms.
Going forward we want to start building new features, and over time migrate existing features, in ASP.NET MVC.
Is such a thing doable? Can we add the necessary files to an ASP.NET web application and thus "upgrade" it to be compatible enough with MVC so that we can start adding routes, controllers, views, etc.?
The old site is using a frameset containing a top header, a left menu, and a main content. What I envisioned was to create a new masterpage for all the existing pages, integrating all of those things into each page instead, and then start adding new pages using views instead.
I understand that unless we upgrade to .NET 4 we cannot use MVC 3, so the way I see it we have the following options:
Build a new website, somehow auto logon the new site with the same credentials when logging in on the main site, and link between the sites. I see tons of problems with this solution. Integrate ASP.NET MVC 2 into the existing software, adding the necessary files, and starting to add new content in MVC style, only fixing critical bugs in the old files, and over time migrate them over to MVC. Upgrade to .NET 4 and integrate ASP.NET MVC 3, pretty much the rest the same as option 2. Wait until we can schedule a full rewrite, likely to not happen in any foreseeable future. Don't do it, keep web forms.
Note that a full rewrite is out of scope at the moment, so some transitional period is the only option we can do right now.
Option 2 and 3 are the ones we want, the rest are just for completeness.
Am using two web application and one web service. My doubt is, am sending the dataset from my first application to Web service. After sending the dataset to my web service, i like to fetch the dataset using second application from the web service. How shall i fetch the dataset by using second application.
Note:
1) sending the dataset from first application to web service. 2) web service receives the dataset from the first application. 3) second application want to fetch the dataset from the web service which was sent by first application.
I have an existing asp.net 4.0 web application and want to add a blog to it. I would like to create a new sub-directory and call it "blog". Is there some well suited blogs for this purpose?
What are the options available to call another web applications hosted in the same server. Eg: i have a application App1 and App2 hosted on the same server.i just wanted to call App2 from App1 how would i do it.
The most important point is that I can not change the url on the address bar to call the page of the 2nd web application.
Whatever I have achieved so far is I have added a link to my 1st application which redirects to the 2nd application, but it is changing the url on the address bar, I want to redirect to the 2nd application from within the 1st application.
I've a little problem, with a ASPX .NET application that I'm updating. After having updated the DLL and the ASPX files on the production server, my application is still running not modified. Is there a method to force IIS reloading the application without restarting the server?

I am little confused regarding the concepts of localisation and globalization.I was working on a project which was totally database driven. All the data, images and flash stuff was coming from the database. Now the site is fully loaded with the data.Now the client wants the currently running site in 5 different languages. So I read the resource files concept. Now the confusion arises. I have 2 types data on the site, one is static(ie text on labels, titles, buttons) and dynamic data that was added from the admin panel.Now my question is: If at this stage I want to make the site in 5 different languages, then I have to make the resource files for all those languages so that the static data can be displayed in different languages.But what about the dynamic data that was entered by the client. Client uploaded huge amount of data. Should I make the changes in the database tables and add 4 other columns for different languages and again upload that much data in those 4 languages.
1)My Windows services application folder is MyWInservice
2)Executable .exe i.e. “myServices .exe“ file located under MyWInservice \myServicesinDebug
3)I have RUN bat file C:WINDOWSMicrosoft.NETFrameworkv2.0.50727InstallUtil.exe /u "myServices.exe" C:WINDOWSMicrosoft.NETFrameworkv2.0.50727InstallUtil.exe "myServices.exe"
4)After running InstallUtil, myServices.InstallLog and myServices.InstallStategenerated under .. binDebug folder.
5)Upon pressing F5, I still get the same error. Error is:
Windows Service Start Failure,Cannot start service from the command line or a debugger. A Windows Service must first be installed (using installutil.exe) and then started with the ServerExplorer, Windows Services Administrative tool or the NET START command.
