I'm building a silverlight LOB application which uses both RIA services and a vanilla .ASMX service..
The data is wired up using entity framework..
I have 1 entity which i recently added a 1 to many relationship to a collection of a new type of object..
Using RIA services i can get to that in my silverlight application fine by saying:
instanceOfEntity.NewEntities
However in the vanilla service which is using the exact same object context class even after updating, deleting and recreating the service reference in the silverlight application.. the property is still not being exposed..
Someone Plleeaeeeeease tell my how i can get this dang thing to show up via this service!
Thanks
Daniel
Ended up switching to a WCF service instead..
Seems to work fine,
Not sure if this is a limitation in vanilla ASMX services?

I want to build a mid-size application using NodeJS and NW.js (formerly known as node-webkit). The application will grab some data from the internet but isn't talking with one special service which is under my control.
Is it a good idea to use AngularJS nevertheless or is the MVC approach of Angular oversized if there isn't neither a database nor a webservice on the controller layer?
I think Angular would be really fine for databinding and GUI handling, but I'm not sure if it's the right approach for this kind of application.
I see no reason not to use Angular in an nwjs project. I do it myself in the app I just finished building. It's a local-only deck tracking app for hearthstone that never communicates over the internet at runtime. It only ever monitors a log file that is generated by the Hearthstone game. Since the way I'm display information to the user is still technically a web page with a full DOM, Angular makes perfect sense since I'm already comfortable using it.
I have a silverlight application, it has pretty complex UI. In some forms I am using MVVM pattern. However there are many forms where code behind file has most of the form logic code (no view model).
Silverlight application is having both business and UI logic. There is a WCF service which SL application is directly calling. This WCF service is a data service (DB logic).
I want to migrate silverlight application into HTML5. I have following questions.
There are many links to migrate the SL application to HTML5 (even using MVVM pattern). Many suggests to use some JS framework library like AngularJS/Knockout. Can you please tell me which one works best for migration from SL?
Where would I put the business logic? Can I write my business logic using JS library? Also in case I write business logic using some library then won't it expose all my logic to client?
In case JS library is not the right thing to write the business logic then what other technology I should use? WebAPI or something else?

For Server Side Code Reusablity (MVVM) Code use AngularJS/KendoUI
Use C# Object to JavaScript Object Convrsion
Server Side Logic we can Re-Use, Client Side Logic C# to Java Script
User Rest API's
I am wprking on a project and I have 2 projects in one solution. I added my WCF project and inside it I added an entity framework. Also in Service1.svc I can reach the classes and use them for saving like
public bool saveuser(User user)
{
}
For example User is the name of my database and Its pretty fine working in WCF part but at WPF part Im trying to access this class again to fill this class's object and I using MyClass.ServiceReference1; on the top and Inside one of my method I can not reach this class. What should be the solution why I can not access my class instead I added this WCF service as a service reference and enabled async operations.
Im newbie and thanks

I'm using RIA Services authentication in a Silverlight app and it works great. Now I want to add unit tests using Moq framework: http://code.google.com/p/moq/
The problem I'm having is that I can't simulate none of the methods exposed by WebContext.Current.Authentication, since I can't return custom values for the mocked methods. For example, I can't simulate a successful login since I can't set a value for LoadUserOperation.IsComplete because that property doesn't have a public setter. The same happens with all the returned structures: they are readonly!
Is there a way I can simulate the authentication operations and therefore test the login in my app?
Thanks in advance.
I show how to mock authentication in this post.
Thanks for you help.
I found a solution after refactoring the code a little bit and adding proper interfaces and wrappers for the RIA services sealed classes. This guy shows how.
I was using a simple WCF service with silverlight but I wanted to validate data with annotations and I didn't want to write a whole new layer in silverlight project. So I decided to switch to using a DomainService, created through generating code in the silverlight project.
Now comes the trouble. I have a parent class and about 10 derived classes. Through WCF, I was able to just use the base class. Now I am trying to use a DomainService with the base class decorated with the KnownType attribute. The problem is now those attributes get replicated in silverlight client and a compilation error is thrown. Anybody know how to use DomainService with inheritance? I want to deliver only the information from the base class.
I don't completely follow what your problem is, but this is a great tutorial on how to use Domain Services in Silverlight, and the example includes an abstract base class for all entities, similar to what I think you're doing.
