• New user experienced start windows:
  The first new feature that has been introduced is that from now on the new start window will appear in the Visual Studio 2019.  It will consist of the below mentioned options.
  
  • Check the code.
  • Open a project.
  • Open a specific folder.
  • Create a new project.
• Visual Studio Live Sharing:
  This is another feature introduced that will enable a person to directly share code context and the debugging processes with all the other team members and also get a live access within the Visual Studio just like the google document services. With the help of this live sharing feature, all the team mates will be authorized to edit, debug, read and also navigate the project that is being developed in a very secure way and without any disturbance.
• Improved Refactoring:
  It’s purpose is to organize the codes in a structured manner. Visual studio 2019 has this feature in it that will be of great help to the developers.
• Improved Search Experience:
  Improved search engine is one of the most useful features that has been added in the Visual Studio 2019. This feature works faster, effectively and gives out best and more enhanced results. This feature was also available in the previous version by the name of “Quick Launch”, but now the new search experience ensures more effective search results. Now the search result is also going to show you different suggestions as soon as you start typing anything in the search box. This will eventually lead to better search results.
  
• Searching while debugging:
  This is another amazing and useful feature added that will help to search suitable objects and suitable values while the process of debugging is in process. As we know that debugging is a procedure where a number of errors are identified and then removed from a software. Searching for suitable objects and values while debugging can turn out to be very helpful for developers. So that is why this feature has been added as well
  
• Code cleanup in one click:
  This feature is going to detect different warnings and give out any suggestions in just one click. Having this feature is the Visual Studio will help the developers to format the code and also make the necessary changes in the coding format that will be suggested by the settings and the .editorconfig files.
  

• Performance and Productivity:
  • Intellisense with filtering option increases usability
  • Support for  Unit Testing with multiple frameworks including MSTest, NUnit and xUnit.
  • Powerful Navigation with structure Visualizer
  • Can notify in real-time about violation in architectural dependency rule.
  • Access to Inner Exception instantly.
  • Improved Debugging and Diagnostics
  • Grouping Find All Reference Results
• Mobile App Development:
  It supports building Mobile Apps using C#, JavaScript and C++ for Android, iOS and Windows devices. Visual Studio  2017 also makes easy to  record the test actions using VS 2017’s mobile test recorder.
• Cloud App Development with Azure:
  Easy Cloud Application Development with Azure
• Redefined Fundamentals:
  For me as developer, Visual Studio 2017 starts faster using less memory as compared to previous versions. It provides the option to load solution faster with “Lightweight Solution Load” option under Tools.
  Goto Tools, then Options, then Projects and Solutions, you will find this option “Lightweight Solution Load”.
  

• Improved Code Editor: The Code Editor has been already replaced with the so called “Roslyn” compiler to provide you an improved and exciting code editing experience. A light bulb is shown when you have to include some code fixes , so anytime you see a light bulb, click it and you will get suggestions that is based upon the analyzed code.
• Custom Layout: The full potential of this feature can be used on multiple devices. Let’s say you are about to use a Surface Pro to develop on your bus ride home and a 24″ monitor from the comfort of your home. In order to quickly switch devices go to Window – Apply Window Layout. Keyboard shortcuts is also supported so that the user can quickly navigate to any familiar layout.
• Shared Project: Probably you have been a witness of an event when you wanted to use a Shared Project option right outside of Windows Universal Application, now IT IS A REALITY. After a quick search you will find the Shared Project in the list of the new project window.
• Single Sign-In: This one is undoubtedly much awaited feature. As these days, we developers, are using cloud services for multiple purposes. So, managing these services with different sign-in details in Visual Studio was annoying as authentication alerts were required for accessing these integrated cloud services. With Visual Studio 2015 single Sign-In support is provided, so once we are authenticated with first cloud service, no more authentication needed (Coooool…..).
• Smart Unit Tests: IntelliTest in Visual Studio 2015 has the capability to explore our code to generate test data and a suite of unit tests with much improved code coverage.
• Emulator for Android: No doubt the Android Emulator is a true relief as you can use it in Visual Studio 2015 as a cross-platform project or VS Tools for Cordova. It supports a variety of sensors and simulations, also GPS Location, Screen Rotation,  Accelerometer, SD Card, Zoom, Multi-touch, Camera and access to network also.
• Renaming Enhancement: Before the user renames a variable or an object, Visual Studio will highlight all affected instances making it easy to identify all the changes to be made. Also there is a new dialog window that shows the number of changes or even conflicts for a renaming operation.
• Editor Touch Support: There is an enormous boom of touch sensitive devices and monitors nowadays, so Visual Studio 2015 had to come up with touch based support. You can use the touch screen for scrolling, gesture zooming, line selecting and also a new functionality was added to bring up the Editor context menu.
• Support for JavaScript Editor: Working as a web developer on Microsoft Platform, it’s always been difficult to work with JavaScript within Visual Studio. Although Visual Studio 2013 has improved it’s editor for JavaScript but in Visual Studio 2015, JavaScript editor has been updated with number of amazing features as:
  • Intellisense support for object literal
  • Expand/Collapse JavaScript code sections
  • New Navigation Bar for navigating between elements in JavaScript
  • Support for New JavaScript Features (ES6 version)
  • and many more…
• Custom Window Layouts: Most developers are familiar with their own window configuration. Let’s say you work on a JavaScript based project, then you will need a much larger code editor window whilst with a web project you may want to open the solution explorer window.

These are many other features introduced with latest version of Visual Studio. You can get a complete list of these Online at Visual Studio Website.

• Throw-away applications: In Visual Studio 2013, the new project window looks a little different. If you want to create a new project, the name and the location no longer have to be set immediately. It is a good option when you are about to test something and delete the project right away, so you don’t waste time.
• Code-lens: A feature that is available only in the Ultimate Edition. A real time saver, as by default, it shows the number of times a method or property is referenced in your code. Especially useful feature in larger project where you are not familiar with the entire source code.
• Customizing Scroll Bar: The possibility to customize the scroll bar just gives the user a much better overview of larger files. A user can set the scroll bar to show breakpoints, errors and much more.
• ALM (Application Life Cycle Management) features including agile portfolio management, web-based code comments, web-based test case management, change-sets and commits etc.
• Creating Azure Website from within Visual Studio 2013 by installing Azure SDK and connecting to Azure.
• Live debugging in Azure
• Live Tracing from Azure
• With .NET framework 4.5.1, just like 32-bit Edit and Continue, now we have with 64-bit also.
• Better Navigation & Search
• Open a method definition by using Peek a Definition feature.
• Handy feature of resolving type by resolve menu.

• While the Visual Studio 2010 already included an emulator for Windows Phone devices, the Visual Studio 2012 Simulator is much more powerful. It enables debugging apps for various scenarios that you just don’t have natively on your own machine.
• You can also develop Windows 8 apps that strictly require some hardware support such as touch, rotation and different target resolution.
• It is unimaginable to build quality applications without good IntelliSense. Therefore, the developers put enough effort in Visual Studio 2012 to make it more efficient and productive.
• An even more important feature is the JavaScript Console. The good news is, that you can play with the source code modifications while the application is running.
• Runtime Debugging Tool i.e. DOM Explorer for debugging HTML/CSS.
• Asynchronous Support in C#/VB
• Team Foundation Explorer Window
• Code Clone Detection
• Project File Compatibility with Visual Studio 2010

• IntelliSense improvement: One of the most important and time saving feature. It is so comforting to wonder how many hours a programmer can save thanks to IntelliSense. For those who don’t know, it is that wonderful drop down list that automatically completes existing member names or type names. This feature can amazingly speed up your work as you don’t have to type so much on your keyboard.
• Toolbar Items can be easily found: Each new version of Visual Studio has an exponential increase of items in the Toolbox. Until the release of VS 2010, the items where categorized into collapsible sections and searching was managed manually by the user. Fortunately, the new version of Visual Studio offers a search via keyboard.Simply click on the Toolbox so that it is focused and just start typing.
• Improvement in Searching: Visual Studio always supported different search features , but the fact is that it was a little clunky. In other words, the search feature was limited to searching for specific string in files. This feature was still available but a new one was added. A search window called Navigate To. You can navigate anywhere in your project by typing in the name of a method, class, an event or even a file name.
• Multiple monitors: It is statically proven that using multiple monitors can improve a programmers efficiency by 50%. So, visual Studio 2010 has feature for detaching window outside the IDE.
• Highlighting References feature in Visual Studio 2010 can highlight all calls to a specific method or member variables.
• Improved Loading Time for Assemblies in “Add Reference”.
• Support for Targeting multiple .NET Framework during Application Development.
