I am building a Silverlight 4 app that's going to be out of browser with elevated privileges - what's going to be the simplest and most direct way for the clients to access the SQL DB on the Server.
I need to finish the project as soon as possible and I don't know how to use RIA Services - so I will and never used Web Based services - I will really appreciate if you give me the simplest and most direct way - and link to some sort of explanation about how you implement it.
Thanks.
Using RIA is not so complicated as it seems at a first sight...
Look into links below:
Get Started with WCF RIA Services;
Using WCF RIA Services;
WCF RIA Services
Second article will be the most useful in short terms.
You have to use web services:

That link has a tutorial, but this is a more recent one on how to do it: http://www.codeproject.com/KB/silverlight/CntDbSlght.aspx

I need to calling our C# Methods from another server to perform some Action. I use C# in both servers. One is our Service Application, another one is a WPF application where I consume my Service.
Prefer I use a WCF or WebAPI service for Service Application?
Most People prefer to use Web Api, but web doesn't expose metadata for creating proxy by service.
which one is simple and better choose?
You may use either WCF or WebAPI, if multiple platforms (Mobile, Web, Other Service) are going to interact with your service, then I would recommend Web API, otherwise you may use WCF. Similar discussion has already happened in another question, please refer this link, hope this will be useful
Getting a web service and using android to consume them?
I have to use a number of functions provided by a government web service. I have no idea what they used to implement this service. Could have been COBOL for all I know.
My problem is that I've been trying to access this service using the security features provided by WSE3.0 but have had no luck. I'm consistently getting errors regarding the certificates.
After some research I've realized that WSE3.0 is essentially defunct and I should be using WCF. But, I'm only writing a client and most literature seems to refer to the services themselves.
Is there even such a thing as using 'WCF' to write a client? Should it matter which I use?
Thanks in advance.
Sure, WCF is a great choice for writing a web service client. Here is how to create the client ("add service reference"). After this you need to create the binding (just like in the service samples).
I want to create a restful web service that can accept json and returns json responses on a Windows server written in C#.
This particular service will actually have a long running background thread, so a WCF service hosted in IIS won't work (as far as I can tell, IIS will stop and restart the service on/after each request).
In general, I do not really even like WCF since I don't like dealing with generating proxy classes and updating service references down the road.
How can I accomplish this?
Well, with respect to WCF, is a technology already proven to help you build robust services, during your software design process you can design the service to keep state, hosting singleton instance, etc, so your impression of WCF services are somehow incomplete.
Now, regarding the restful approach, the technology used nowadays is called Web API, you can see some examples in the following website : http://www.asp.net/web-api , this will help you to avoid the tipical WSDL and generating proxies that you are talking about, and you can have bare-metal RESTful queries like "(http://myapp/orders/?id=1) that could return a json object with the orderid=1
Here you can have info for the instantiating mode in WCF services: http://msdn.microsoft.com/en-us/magazine/cc163590.aspx

I want to learn doing RESTful webservices. I have surfed the web some hours and think that I have a good overview over what RESTful services are and now want to build my first service-application. I have a good small project that seems perfectly suited for doing it with a RESTful webservice.
I have seen that WCF has the ability to build RESTful webservices. My question is, if it is reasonable and efficient to write RESTful webservices with WCF or if there are better suited alternatives for writing such services in the Microsoft programing environment.
(As additional information, I already have experience in using WCF, but more in using it in a RPC-way. But I don't think that this is important for my question anyway).
WCF supports RESTful services via the webHttpBinding. This works but doesn't give you alot of control for working with the HTTP protocol itself (although some things got better in 4.0)
The next version is going to have a lot more support for RESTful services. The team are being very open about the new Web API so if you are not about to put something into production then I'd start with the new API
WCF is perfectly valid and very capable of handling REST services - you won't go wrong with that!
And there are a couple of alternatives out there, too - check them out and see which one suits your needs best:
RestSharp
OpenRasta
RestDotNet (clients only)
and probably quite a few more....
I have a .NET WCF service which is implemented in a hand full of of projects in VS2010. Is there any way I can create a new project which merges together all of the service contracts and operation contracts into one DLL to distribute to clients?
In short, I want to distribute a single DLL to clients to hit my WCF service.
I will provide more information if needed, but I'm a bit of a WCF noob.
thanks,
Mark
I think this is just the article you're looking for:
WCF the Manual Way... the Right Way (link)
It goes into detail on how to manually create proxies to do exactly what you're asking for.
Hope it helps!
