Need help to related latest technology of .Net.

MVC- ASP.NET MVC, which is simply a different design pattern to build your applications with as opposed to Web Forms. It requires a slight learning curve, especially for those coming from a Web Forms background, but once you get the hang of it, you'll be fine.

LINQ - With a simple reference to the System.Linq assembly, you'll find that you can use LINQ to perform complex queries of either your databases or any collections of objects (such as Lists, Arrays, etc) with ease..

SignalR - An incredible real-time framework that leverages Javascript and allows you to create real-time applications that not only allow the client to push events to the server, but the server can actually push out events to the client.

Entity Framework - You don't see old school ADO.NET connections as much as you used to since the introduction of Entity Framework, which is an ORM (Object Relational Mapper) tool that will allow you to easily access and manipulate your database by creating classes to work with instead of writing SQL code.

Web API - Web API is the latest method of writing and handling Web Services within .NET and acts a type of replacement for older WCF services that you may have used within the past

SPA - Single Page Applications are another very recent release and a different type of application from those using MVC or Web Forms and leverages much more on using Javascript-based frameworks to handle accessing and presenting data to the client.
