Apart from using ADO.NET Data Services or WCF Services,When i want to use RESTful services in ASP.NET (consider if i want to use it ASP.NET 2.0), do i need to download any specific API inorder to use Rest Webservice.If so,where can i download the same?
If there is any possible way to upgrade to .NET 3.5, then I highly recommend that you do that and use ASP.NET MVC. It's built to handle a good number of things you would have to build from the ground up (the most important being path mapping) and it will save you a tremendous amount of time.
While it could be done in ASP.NET in .NET 2.0, it just isn't practical given the amount of work involved and the fact that it's already done for you in a later version of the framework.
Visual Studio magazine did a decent article on how this could be accomplished in native ASP.NET 2.0.
I read over it briefly a while ago and it was a good overview of how you could do it without any external dependencies.

I am working on my first .NET Web API. I have an existing .NET Windows Forms application using a SQL Server 2008 R2 database, and now I need to write a new app: a straightforward Android tablet application that will access the same database. These apps for just for internal use; not outside the one company.
I have been on a long journey though many tutorials, blogs and posts here, including this I'm lost. What happened to ASP.NET MVC 5? super helpful explanation of .net products and versions. But over and over I get hopelessly confused about which product I should choose to write the Web API. I can't always tell from some of the tutorials whether the ideas and techniques and configurations apply to both .NET Core and .NET Framework, or just one, and if the tutorial works with current versions. I am using Visual Studio 2019.
Does anyone have a recommendation for whether I should be using .NET Framework 4.8, or the new .NET Core?
I do not find this guidance from Microsoft helpful.
I think I should probably use Entity Framework to generate code from my existing database, but I also think I could pretty quickly code SQL calls right into the Web API controllers as I have seen done in some tutorials. Is that considered a bad practice?
Thank you for any steering you might offer.
Microsoft offers Pipeline Development via its Extensibility framework where the application can consume External Addins. I have successfully developed an extensible application on a Windows Console Project.
Now I need to implement an extensible website which accepts Addins, I googled for days for guidelines to do so, unfortunately I couldn't find any resources.
So, my question: is it possible to do that ? if yes can you provide any resources to learn from ?
I found out that you can't use M.A.F with Asp.Net because the Grabdge Collection will be very ugly.
Instead if someone ever will counterpart this question, The answer is:
You will need to use M.E.F (Managed Extensibility Framework) which comes as part of .Net 4.0+
I am trying to migrate a project from classic ASP.Net Web Forms to ASP.NET MVC.
While I have read through http://www.codeproject.com/Articles/38778/ASP-NET-WebForms-and-ASP-NET-MVC-in-Harmony. I have a basic idea on how the code structure, libraries and routing should be done.
For your information, the scope of my existing project is around 400 pages and 300 tables.
On top of my head I have two approaches:
Start from stretch, rewriting the whole system - Obviously this would require intensive work and take a long time. Any change made on existing system would need a duplicate change made to the new system.
Migrate the page one each - I still have a rebuild the entire core library (for accessing db), and get the page migrated one by one. For this I would assume to have two core libraries (new and old) running simultaneously with different pages connect to one of those.
Would anyone have similar experience and advise a proper way to start?
For this complete revamp I may also target at the latest technology - .NET Core and MVC6, by taking these would I have extra advantage, or some blockages I would have to take care of?
Any suggestion and opinions are appreciated. Cheers.
Microsoft is a bit hush hush on the subject but the WebForms engine is probably never going to make its way to ASP.NET Core. One might think that MS is waiting to see if the community is calling for a port, but I think they're trying to kill it discretely (not like Silverlight).
Why? Because it proved to be a bad good idea on the long run, easy to use at first, but extremely complex to master (because of viewstate and page lifecycle), with a tendency to allow average developers to build very tedious application (in french we say steam factories). Also it was very poorly adapted to modern web development (Ajax, unit testing, IoC). They tried to fix it with a couple of tweaks, but the overall architecture is just not adapted to this kind of things. MVC is a treat in comparison!
To answer your question, it's not really possible to migrate WebForms to MVC, because those are quite different architectures, and of course the architecture is what an application sits on top on, so if you change it, you might as well rewrite it from scratch.
What can help you a lot is if your app is divided in tiers (business, data access, UI). If it's not the case, you could start by doing this, properly separating the UI project from the rest. Then you would just have to rewrite the ASP.NET project and not the rest.
There are some useful resources I'd like to share with the StackOverflow community just in case you are having troubles to decide what to do:
modernization of your existing Web Forms app
migration to MVC or Core
or whether to start a new project on Web Forms, MVC and Core.

DotVVM package helps us to migrate ASP.Net Web Forms migration to ASP.NET Core without re-writting completely.
i have not tried any production application. still have tried some sample pages. you can try this out.
I can agree that for many cases a re-write of an ASP.NET application where WebForms is used widely may do not provide any business value.
Therefore we decided to use our experience with ASP NET WebForms to develop a highly compatible port of WebForms for ASP NET Core / .NET 6.0.
We use the solution in our own ASP NET WebForms-based products and projects as well as a licensable component library.
So the Forms can still be used and you can focus on the .NET CORE/6 migration.
Or is Rails by itself just good for developing APIs?
It seems that ASP.NET Web API project types have some history intertwined with WCF (as is detailed in this post for example), so maybe it's not applicable to Rails.
UPDATE
To clarify, Microsoft has the ASP.NET MVC framework. Recently, they came out with a framework called ASP.NET Web API. ASP.NET Web API seems to have similarities to ASP.NET MVC, but is specialized and trimmed down for RESTful web services. Is there an equivalent in the Ruby/Rails space?
So, the answer is Yes to both questions. Rails does have an equivalent and its Rails.
ASP.NET Web API looks like at it's heart is just a RESTful router with type negotiation. I could be totally off base here, but from the tutorials I saw that's what it looked like to me.
So yes, from what I can tell, Rails supports most of the things that the Web API was created for. In fact in Rails most of this stuff is forced onto you until you become informed enough to be able to change it (assuming by that point you know better than to actually do that).
But, as far as Web API functionality. That really comes from the ability to support HTTP verbs (GET, POST, PUT, DELETE) which Rails does.
But a source of confusion might be that in Rails the RESTful API is actually the application itself. Meaning you don't need to implement any other libraries, it's just built that way.
Here's a quick example of that I mean
When you hit /users/1 you will get the data associated with that user depending on the format you requested. So if you request JSON the controller returns JSON, HTML you get HTML, XML you get XML, etc. (As long as said format is implemented for that resource)
A good overview of what I'm talking about are in these two sections:
Rails Guides::Controller: Rendering xml and json data
Rails Guides::Routing: Resources on the Web
So you could build a website, API, or both in a Rails app and they would all start the same way.
But from my limited knowledge on the matter, I would say a ASP.NET MVC with ASP.NET Web API program is actually a lot more like a Rails Program than the regular ASP.NET MVC programs that came before them.
Or it's all just a clever ploy to get as many Capital Letters in a title as humanly possible.
Take a look at grape. It is a pure "Rest" HTTP API framework in ruby.
WSO2 looks like a generic web services framework (as opposed to MVC like Rails) I can't vouch for it but it seems to be more a service framework in the style of WCF Web API (service in the generic sense, not just SOAP).
It's difficult to know what you mean by "APIs"... Rails and ASP are used for developing web sites, and WCF is essentially a web service platform. ASP and WCF have little in common, it's just normal for ASP applications to consume WCF services because they all run on the same stack and platform.
I suppose Rails on the Microsoft side would be a combination of ASP.NET MVC, Linq2SQL or EntityFramework and some WCF.
Ok, this isn't a direct answer to your question, however there seems to be some confusion... Microsoft's ASP.NET Web API is specifically a product offering with ASP.NET MVC 4+. It is a RESTful framework. How does it compare to RoR? I don't know having never tried to install RoR on Windows. As with anything else, experiences vary... Requirements vary. Also try to think ourside the language, construct, context, and framework. Is it better for developing API's? If you're using Linux/Unix, the answer is probably a yes. If you're on a Windows server, the question is a bit trickier.
Finally,
Writing in the ASP.NET Web API will have 0% to do with WCF. Perhaps it is implemented as such under the covers, but the ASP.NET Web API is (from what I've seen and done with it) strictly an HTTP bound API, not TCP/Binary/Piped/etc... like WCF. If you're ask
Yes. It's called Grails. It uses spring. There are tons of plugins available for it and it make creating webapps a breeze. Read more about it here.
I am starting a new project which will need a ASP.NET MVC 2.0 website, a Silverlight section and a Windows Phone 7 UI.
My plan was to use WCF RIA Services to create a set of services which would be used in all different UI projects. With the Silverlight project I would use the standard tool integration, the Windows Phone looks like it may have to be WCF Services exposed by the RIA Domain Services, but I'm not sure about the ASP.NET MVC website.
My initial thoughts I would simple reference the class library containing the Domain Services and use them directly. Could this be considered a viable approach to using RIA Domain Services in a ASP.NET MVC website?
Kind Regards

I know a long time has passed since this question was asked, but since I had to make such a decision, I might as well document it for the benefit of others.
I work in an environment where lots of legacy and new apps co-exist, with the legacy apps being phased out. So we've had to build interoperability between everything from MS Access, to web service end points in C#, VB, Web Forms, MVC 3, even Flex, Reporting Services...the list goes on.
One of the biggest pain points in a multiple-client scenario is the maintenance of interoperability over time. As data, requirements and delivery mechanisms change, keeping things smooth ends up taking a lot of resources.
My approach has been to create one and only one mechanism for reading a given source of data by defining 1) a model, 2) a serialization/deserialization layer and 3) a service layer. All projects that need to use XY_Data must use the XY_Service to get XY_Objects via the XY_Serializer. Direct db calls or stored procs, etc are allowed in the XY_Application. This allows me to drop in replacement DLLs (versioned) with bug fixes and upgrades without restarting anything. I hardly ever do a full publish.
So yes, what you're suggesting will work. I would recommend only that you rigorously enforce the single-source-of-truth and DRY policies both in your data and your APIs.
