The ability to use SQL with Entity Framework Core has always been a cool feature. There's a new feature in Entity Framework Core that opens the door for whole new set of SQL-related functionality.
If you're wondering how to start integrating TypeScript into your development practices, here's both when to do it and how to do it.
Proving that Visual Studio tools can come from all manner of sources, a small dev firm in the Canary Islands is offering up its own homegrown toolset -- developed during the creation of an accounting program -- as a commercial product to let C# and VB.NET coders create Web apps without all that JavaScript and CSS stuff.

Entity Framework is fabulous ... but it does impose some overhead. If you like working with data in an O-O kind of way but feel the "need for speed," then you should be looking at Dapper.

If you need to create a version of a class from several sources or just want to merge default values with a user's input, object spreading solves your problem. JavaScript won't let you do this (yet) but TypeScript will.
If you're building services it's critical that you support the developers who will create and read your service's messages. JSON Schema lets you support the three principles of good message design in a way that supports developers.
You can dramatically simplify life for developers creating services and their consumers by following three rules for designing messages and then enforcing your message formats with JSON Schema.

If you're building services, then getting your message formats right can be the difference between success and failure. Here's an example of what can go wrong and how it could be fixed.
View components let you create reusable chunks of business logic coupled with a UI in multiple places in your application ... and then let you share that logic across multiple projects. Here's how to invoke them and share them.
ASP.NET Core lets you bundle up business functionality along with its related UI into a view component that you can reuse in throughout your application.
Web workers in TypeScript give you concurrent processing but they can be awkward to debug. However, if you set up your web worker code as just another function, you can simplify debugging (or even build your web worker dynamically at run time).
Once you've created a JSON Schema that describes a JSON document, you can use it both in Visual Studio -- to provide guidance when creating JSON documents -- and in your code to validate the messages you're receiving.
Peter tries out Visual Studio Enterprise 2017's Live Unit Testing and has what might be a life-changing experience.
If you're thinking about moving to the cloud, the first step might be the easiest.
Here's how to use web workers in ASP.NET MVC with TypeScript to enable concurrent processing in your client-side code. And, as a bonus, the correct way to think about web workers.
