I'm pretty new to Silverlight/RIA/Asp.Net thing, and I'm trying to figure if an Asp.Net website is required (for hosting the app) if I wish to use RIA services with Silverlight?
You could use a Web Application for hosing the RIA services in which is a compiled version of a Web Site. This is a distinction made by Visual Studio for different types of web projects but that might not be what you mean.
Really though RIA is just web service that takes a certain set of parameters. You technically could use PHP and generate the same content although that seems like it might be a bit of work unless there are frameworks that already do this.
Your RIA service will need to live somewhere online though. You don't need a website with web pages but you will need to run the service in a web server like IIS and that means it probably needs to live in a web site, even if the website doesn't have any web pages.
No, you can not use RIA services without an ASP.NET application. While it is true that you can create the backend data service with PHP (or a number of other web technologies), that would not be making use of RIA services.
The basic idea of RIA services is to provide a super simply means of plumbing your data classes through ASP.NET. Mostly it is used in conjunction with an ORM and additional metadata classes in your web application. You then provide a service to manipulate your data. When you compile the solution than the work you did in the web project gets pushed into your Silverlight application (through code generation).

I have an application which is built in ASP.Net WebForms and Silverlight.
There is another WCF services application which is accessed by silverlight part of my application.
Now I have to Re create the whole application in an MVC Single Page Application(SPA) and of course the WCF one because now I would need Web API for that.
An initial solution comes into mind is to add a web api project into wcf services application and start creating web methods there and call wcf methods from there if that functionality was already there.
And for webform start a new spa with mvc project from scratch and use durandal or any other spa client framework(hell of coding).
Any useful solution/advise? as I am looking for simplicity.
I searched around and found some questions but really did not helped as they are about merging with existing apps.
Note: application is a large application with a lot of functionalities
You have to decide how confident your team is with client side frameworks. Development of Single page applications may not be easy in the beginning, but you will get used to it very quickly. It's very important to give your team the right training.
In my opinion, Durandal is the simpliest, most elegant and complete framework to build enterprise level SPAs. It is important to know how knockout, requre and durandal's router and composition work. For data centric application I would use breezejs to manipulate and cache data on the client side and request it from the server side. Breeze works best with Entity Framework on the server side, but it's not necessary. If you can use Entity Framework, it will simplify your development, because it can generate metadata of your database structure for breeze. If Entity Framework is not an option, metadata can be written by hand.
I would make server side as thin as possible. Serving data from your database using web api with ORM of your choice and some cshtml pages.
Durandal Get Started is a good place to start.
Durandal Auth is a very good template for enterprise level SPA. It may not suit you completely, but you can use it as a guidance to build different modules of your application.
Breeze samples I suggest you consider using breeze. There are good courses available on pluralsight.
Knockoutjs has good training on data-binding.
I'm looking to make a RESTful API on ASP.NET for a website. My problem is that I need it to be integrated into the website and not as a separate project.
I understand that WCF makes this really easy and its the ideal way to do it, but I don't think you can combine a WCF Service Project and a ASP.Net Website, Is this correct?
Is there a way we can do this using a webservice (asmx) file (since I know that asmx services use SOAP no?)
The reason I need this to be in the same project is that the customer will be able to purchase ssl for their domain (which the website is going to use) and I need to make the API secure as well, but the customer should not be asked to purchase two ssl or even a wildcard one.
Knowing this, is there a better easier way of doing this using WCF?
Take a look at the new MVC4 Beta, it's set to go live sometime between March and April this year and should be able to accommodate your requirement to build a RESTful web service alongside a web application. I haven't spent too much time with MVC4 to go into the details, but it's definitely worth a look. Links: Get MVC4; MVC4 and WebAPI blog.
Hope this helps!
You can use ASPNET MVC to build an API along with your website.
See How can I implement a site with ASP.NET MVC without using Visual Studio? for some details on building a basic MVC site.
ASPNET MVC services can respond in JSON or XML, or both.
There will be no special requirement for two SSL certs.
I have an ASP.NET MVC 3 application that exposes both WCF REST services. I'm using .NET 4. You'll have to pay attention to how you configure your routing. For example, my WCF services are prefixed with something like "api/v1/" while all other requests are handled by ASP.NET MVC 3.
I had a problem because IIS refused to serve some "localhost" requests (like when your MVC 3 controllers try to consume your WCF rest services). That was solved by adding an entry to my hosts file. Also be aware of this when implementing an OAuth 2.0 Resource Server or Authorization Server.
Using WCF for REST services works ok in .NET 4, but the JSON serialization sucks big time. There are issues with default dates and it is rather slow. You may want to look at using a different serializer. With WCF you sacrifice some flexibility for some features you get for free.
ASP.NET MVC 4 (and the WEBAPI) is still in BETA, so I'd avoid that for a project with a short term release date.
I'd actually use NancyFX. Setting up routes is super-easy, and it comes with built in XML and JSON serializers that act based on the data in the headers.
I have several asp.net website projects for various sites.
Currently I want to add REST API's to these projects so I can start developing mobile apps (using HTML5/JavaScript/CSS3 and PhoneGap) that make use of these webservices.
Since WCF is far more powerful than regular asp.net webservices (among others with control over the service and authentication/authorization), I'd love to add these to my existing website project.
I did a Google search but cant find anywhere a step-by-step tutorial how this can be done. And also if there's any functionality I'd possibly loose when adding WCF functionality
I was also thinking of creating a new project specifically for WCF, but think I'd rather add it to an existing website project.
Can anyone help me with this?
Depending on exactly what your needs are and how your current web site is configured, there are two approaches.
If you are using a Web Site Project, then you should create your WCF service in a different application:
1) Create a new ASP.Net Web Application Project.
2) Add a new item to the project and select the type of WCF Service or WCF Data Service.
When you deploy this project, you will deploy it to your web server, but not as part of your web site since configuring the web.config will be a large manual effort.
If you are using a Web Application Project, then you could add the WCF Service directly to your existing project. However, I only recommend this approach if you are Silverlight applets within the web site that rely on the user's authenticated credentials.
WCF can be configured with a lot of bindings and it can be configured to return xml or json(.net 4.0). Try to create a wcf service configured to use basichttpbinding or wsHttpBinding and to format the response as json and use jquery to interact with the wcf service.

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.
First off, i'm fairly new to programming, I've built a few asmx web services but I am a little lost regarding how I should set up a WCF web service. I've tried to research this over the past couple days by reading through a lot of the documentation/articles/videos on MSDN but I'm still a confused.
Since my current web services are hosted on a separate box using IIS, from what I understand I need to create a WCF Library, then reference the Library in another WCF App and then host that app in IIS and reference the WCF App from my Front End? Seems like an extra step to me...? Not to mention a pain when developing on my local box.
Any advice or a point in the right direction would be very much appreciated. Thanks!
WCF gives you the option of sharing common assemblies (i.e. so both your service and clients can use the same domain model library), but it's not a necessary step.
You can host a WCF service through ASP.NET, same as ASMX. The "WCF Service Application" project template in Visual Studio configures it this way by default - as a WCF service hosted in IIS.
For the most common scenarios, it's really no different from ASMX. You create a WCF Service application, deploy it to a web server, and add service references in client applications. The importer will automatically generate classes for you, so you don't need to reference any assembly. No extra steps.
If you haven't already, you really should have a look through Microsoft's Tutorial. You'll find the steps very similar to those for setting up an ASMX-based architecture.
