Editor's Notes
- #6 .NET is an entire software development platform that takes care of a lot of the heavy lifting for you when you want to build an application. Applications frameworks help you build the specific types of apps or workloads and enable you to literally build any app for any platform with any operating system. Each .NET workload shares a common infrastructure and .NET Standard library. This means not only are your .NET skills portable, but your actual code is portable no matter what you’re building. This makes it easy to share reusable components (called libraries) across the breadth of applications people build. Additionally, there are a broad set of development tools that makes it really productive to write, debug, build and manage code bases. See: www.dot.net

- #24 Blazor replaces javascript and runs C# on the client side directly in the browsers with no plugins needed. Blazor Server – Works as a web Server (Shipped) Blazor Web Assembly (May 2020) Blazor Renders HTML, but Blazor Native but can render to other things like Native Controls for Mobile.
- #25 Blazor replaces javascript and runs C# on the client side directly in the browsers with no plugins needed. Blazor Server – Works as a web Server (Shipped) Blazor Web Assembly (May 2020) Blazor Renders HTML, but Blazor Native but can render to other things like Native Controls for Mobile. Originally developed as a pet project by Steve Sanderson at Microsoft, Blazor is Web UI Framework which is based on C#, Razor and HTML. Blazor compiles down to WebAssembly, which makes it super (or blazingly) fast (Hence the Razor with a “B”). Blazor allows developers to write client side .net… You may say “Oh, like Silverlight?”… Nope, no plugins needed… It’s just supported natively in most modern browsers.
