what is the real time usage of WS-TRUST and WS-FED - authentication

i read about 2 WS* protocols , WS-TRUST and WS-FED. but i am confused about real time scenario how to use these protocols . can anyone let me know in which scenarios i can use WS-TRUST and WS-FED ? it would be very helpful if someone can tell which is best among these 2 protocols for securing a REST service and a normal.ASPX page.

WS-Federation is for web applications (e.g. ASP.NET WebForms or MVC)
WS-Trust is for SOAP-based web services (e.g. WCF)
for HTTP services you have to look into OAuth2.

Web API vs Window Communication Foundation

I read bunch of articles about SOAP and REST(WCF and Web API).
And after all the reading I end up with understanding that WCF is more powerful, but lots of it's functionality can be implemented in Web API. For example for duplex communication in web API we can use SignalR or sockets. WCF gives you more security with WS-Security, but in Web API you can use HTTPs
So what can WCF give you that Web API cant, except working with lots of different protocols and data formats?
WCF supports more protocols and transports than Web Api, some of then very useful, like SOAP, FTP and MSMQ.
Here you have a table comparing both: https://msdn.microsoft.com/en-us/library/jj823172.aspx
Both has their own purposes, and the table above can help you to choose.
Both of them are using for different scenario WebApi uses full features of Restful services like Uri caching and various other features .Check the below difference I hope it will help you

securing WCF service with OAuth 2.0

I followed the example in the article http://www.asp.net/aspnet/overview/owin-and-katana/owin-oauth-20-authorization-server
this works great for WEB API, how would I secure a WCF service the same way? I would like to have it communicate to the authorization server coded with OWIN and WEB API, is there a WCF binding that will communicate with it? or any other way to do this?

Difference between ASP.NET Web API and WCF regarding the Authentication mechanisms

I am making a choice between ASP.NET Web API and WCF.
I am not quite sure about the authentication part. Could some one shed some light on the differences?
I suppose there would be no actual difference under the hood. After all, the authenticaton mechanism refers to the HTTP request level on the ASP.NET engine integrated in IIS. It should have nothing to do with whether the module responding the specific HTTP request is implemented as an ASP.NET web page, WCF or Web API endpoint.
Nevertheless, there would be some differences in modelling and perhaps in configuration. WCF models the authentication mechanism as a "WCF authentication service" while Web API uses the normal security model of ASP.NET.
Use this WCF and ASP.NET security guide and this Web API security guides as a reference.
Hope I helped!

What is the difference between Asp.Net Web API and WCF Service?

Since last few months this Asp.Net Web API seems to be an highlighted product from Microsoft. Is it an alternative to WS* Service. How is it different than WCF Service? And where can we see it as a best fit in web application development?
ASP.NET Web API is a framework for building web services that are exposed over HTTP. It is very well suited to (but not limited to) building RESTful web services.
Such web services are an alternative to building a SOAP RPC / WS* web services in that they are simpler, more light weight, and there's less coupling between client and server.
A traditional "WCF Service" supports SOAP RPC as opposed to REST, and these services tend to be complex and to have a tight coupling between client and server. Wide interoperability can become difficult to achieve. However, a traditional WCF Service can communicate over a wide variety of protocols - TCP being a particularly useful one for internal services (services in the same DMZ).
(While WCF is mostly associated with SOAP RPC-style services, there are at least three attempts in WCF to support the building of RESTful web services. These attempts have all been superseded by the ASP.NET Web API.)
ASP.NET Web API is a best fit for producing public facing RESTful web services - aka Hypermedia APIs - over HTTP. To do this, having a good understanding of the REST architectural style is important before you start using the ASP.NET Web API. See such books as "REST in Practice", "The RESTful Web Services Cookbook" and "Building Hypermedia APIs with HTML5 and Node".
Difference between ASP.net Web API and WCF API
Web service is a part of WCF. WCF offers much more flexibility and portability to develop a service when comparing to web service. Still we are having more advantages over Web service, following table provides detailed difference between them.

WCF vs ASP .Net Web API

What are the pros and cons of using each technology?
WCF Web Api is now merged into Asp.net
Asp.net web api now supports self hosting.
I still imagine if I want to expose multiple protocol schemas for the same operation I would still lean towards WCF or can Mvc end point do this too?
Also does the new Asp.Net web api expose Wsdl? If not how would the client figure out what operation is available to them?
Arguably the best feature of Mvc is the modelbinder. How robust is the WCF equivalent?
So can someone tell me what advantage does the Asp.net web api bring to the table? WCF seems overwhelmingly the more powerful/scalable choice, imo. About the only thing the Mvc Web Api has over the WCF model is probably ease of development, but that means squat if it ends up being a serious design limitation down the road.
First, I suggest you read my post on the subject:
http://blogs.microsoft.co.il/blogs/idof/archive/2012/03/05/wcf-or-asp-net-web-apis-my-two-cents-on-the-subject.aspx
Regarding your WSDL question - since the WebApi does not use SOAP, it does not require a WSDL, and does not export one. You can use Hypermedia to return resources with a list of possible activity URLs (think of it as a self-describing resource)
The choice depends on what we want to do.
ASP.NET Web API is a framework for building non-SOAP based services over HTTP only - so there aren't more transport protocols available using this framework.
WCF / Windows Communication Foundation is a framework for exchanging SOAP-based messages - here we use a lot of transport protocols: HTTP, TCP, Named pipes, MSMQ, etc...
I am not sure about which one has better performance regarding the amount of data, maybe WCF since we can use low protocols. Any comments are appreciated.
The WCF Web API primarily focuses on REST implementations. If you are setting up a REST implementation, the standard WCF bits are a bit of a pain in the rear. If you are setting up RESTful services, you will find the WCF Web API a much nicer experience. If you are setting up SOAP services, then the WCF Web API is not your best friend, and you are better off using WCF for your services.
Use WCF for intranet/B2B sites n Web API for B2C/C2C/internet sites...SOAP/XML is still the standard for intra-businesses communication n it's not going to go away!!!
