This document provides an overview of ASP.NET Core and Blazor frameworks. It discusses the differences between ASP.NET and ASP.NET Core, benefits of ASP.NET Core like cross-platform support and modern frontend frameworks. It also summarizes Razor Pages, MVC, and Blazor - the different UI frameworks in ASP.NET Core. Blazor allows building client-side web apps using C# and runs on WebAssembly or as server-rendered apps. The document demonstrates how Blazor works and compares client-side versus server-side Blazor. It also includes a demo of building hybrid mobile/desktop apps with Blazor and .NET Multi-platform App UI.

Editor's Notes
- This delineation of responsibilities helps you scale the application in terms of complexity because it's easier to code, debug, and test something (model, view, or controller) that has a single job.
- Blazor is a fully featured single page application framework by Microsoft It has a huge ecosystem of .NET packages on NuGet because it’s compatible with .NET standard
- Blazor is independent of it’s hosting model This means we have options when hosting host Blazor applications. The most common options are Client-Side, and Server-Side hosting. Let’s discuss the two options starting with Client-Side Blazor.
- In a typical application JavaScript is downloaded by the browser It is then parsed, compiled, and turned into byte code before it can execute.
- A more modern approach is to use WebAssembly, which is a standard byte code browsers can execute. What makes WebAssembly different, is that it is parsed and compiled before it is delivered to the browser. Languages other than JavaScript, such as C++ can compile directly to WebAssembly byte code.
- Microsoft has taken the .NET runtime and compiled as web assembly. This makes it possible to run .NET code directly in the browser.
- This is how Blazor enables developers to write .NET code in a client-side web application. Because the .NET runtime is available on the client, we can utilize virtually any .NET Standard assembly.
- If we choose to host Blazor on the server
