Assuming limited experience with OO strongly typed languages.

I've followed the ASP.NET Core tutorial for creating a basic page for building a basic CRUD application. The underlying language is mostly easy to understand, it's the .NET specific stuff that I'm googling (stuff like Model Binding decorators).

What specific C# concepts would you say are a must-know otherwise you'll end up flailing around in .NET Core? For example, in JavaScript, if you want to use React, it's a lot easier if you already know how the DOM works, this, destructuring, functional programming, etc.

Or is it fine to just dive right into .NET Core and learn C# with it as-you-go?
