I hear HTTP endpoints are being deprecated in SQL Server. What takes its place in future?
Deprecated in favor of Windows Communication Foundation. So basically you would write and host WCF services in .NET which will directly talk to the SQL database and then consume those services from client applications.

We host different MVC5 web applications for the intranet(500 employees) on server farms. We want to lightly use signalR 2.2 with SQL Server service broker backplane, mainly for server broadcast. We want to use the same backplane DB for different applications, all applications having acces to the backplane DB server.
Question : 1-Is it to avoid in terms of performance, I didn't see any good practice guidance and it seems to work technically. 2-If a message is broadcast to application1 clients, will it be sent to clients of Application2 also?3-What would be the advantages of using separate backplane DB for each application?
Up to version 2.x, I don't think that is a good idea because it would probably be inefficient. It might work, but the current mechanism would broadcast all messages to all apps using the same connection string (= same server + same database). There is no way to segregate applications on the same database. It looks like there is a plan for it in future versions, but as of today it's probably not recommended.
I have a use case where we will have an ASP.NET MVC Server Application but it needs to talk over a persistent connection to a Windows service. It doesn't look like SignalR does this as it really wants talk Server to JavaScript browsers but I did notice .NET desktop libraries. Can it talk from a server to a Windows server? If not, is there a recommended way, TCP/IP or HTTP to have a persistent connection between the two? NetTcpBinding in WCF?
Yes, there is a SignalR client library for .NET that you can use in any old .NET app to talk to a SignalR server just like you can from JavaScript.
While there is a WebSockets binding for WCF, there is no binding that actually talks native SignalR which adds its own message framing on top of raw web sockets. So, while possible, it doesn't exist today and I wouldn't hold my breath for it ever being created.
Why not simply have a queue using RabbitMQ. And anytime the web need to talk to window service, it push a message into the queue while the window service listen to the queue
There is a WCF Windows Service listening in netTcpBinding protocol, which I understand is Microsoft's proprietary protocol (correct me if i am wrong). I need to write a website that will consume the WCF services. I know for certain PHP can only connect to WCF Service in SOAP (basicHttpBinding or wsHttpBinding) so I need to write another SOAP proxy.
Some comments on the internet suggest that it is possible to have ASP.NET website connect to a WCF Service via net.tcp protocol. Is this actually true? Where should I look?
Your understanding about the netTcpBinding is correct. It is proprietary and accessible only from .NET clients. Since ASP.NET is .NET you could consume your WCF service without any problems.
Ofcourse an ASP.NET web application can connect to a WCF service using net.tcp binding but not over the internet! If the application and the service arn't on the same server or in the same intranet it will not work, you have to choose a HTTP binding.
From my comment below:
Yes net.tcp can work over the internet but not every circumstances it's not recommended (check it at MSDN) to use it. Ofcourse if the whole server control is our we can give it a try but if not (the application and service hosted by a 3rd party member) the chances are not so high to get it work (for example port blocking, the net.Tcp listener is disabled, net.Tcp port sharing is not working or disabled)
Is there any difference between
Webservice and WCF
WCF and WCF RIA Data Services
it seems to be the same.
There are quite a difference between WCF and Web Service mostly in performance and security, also a flexibility and portability.
10 most important differences are listed right: HERE take a look!
A Web Service is programmable application logic accessible via standard Web protocols. One of these Web protocols is the Simple Object Access Protocol (SOAP). SOAP is a W3C submitted note (as of May 2000) that uses standards based technologies (XML for data description and HTTP for transport) to encode and transmit application data.
Consumers of a Web Service do not need to know anything about the platform, object model, or programming language used to implement the service; they only need to understand how to send and receive SOAP messages (HTTP and XML).
WCF Service
Windows Communication Foundation (WCF) is a framework for building service-oriented applications. Using WCF, you can send data as asynchronous messages from one service endpoint to another. A service endpoint can be part of a continuously available service hosted by IIS, or it can be a service hosted in an application. An endpoint can be a client of a service that requests data from a service endpoint. The messages can be as simple as a single character or word sent as XML, or as complex as a stream of binary data.

Asp.net web services are homogenous.
Asp.net web services can use only HTTP chanenel.
Not supports msmq and tcp binding...
WCF is flexible because its services can be hosted in
different types of applications. The following lists
several common scenarios for hosting WCF services:
IIS
WAS
Self-hosting
Managed Windows Service
WCF = Web services + .Net Remoting + MSMQ + (COM+)

I have an Android app that talks to .net web service via http over TLS using self-signed server certificate. Now I am trying to figure out how I can accomplish the similar things (Import server certificate into the app and use http get protocol to talk to .net web service) in Blackberry phone.
Reading an article Blackberry support for HTTPS, my impression was that it might be more complex than in Android (for example, having Enterprise server and MDS between a phone and web server). Can I use Direct TCP Connection?
You can use
HttpsConnection cons=(HttpsConnection) Connector.open("https://xyz.com");
