How to View Microsoft Learn ASP.NET Core Documentation by Version

Introduction

ASP.NET Core has undergone relatively frequent changes between versions.
For example, Blazor in ASP.NET Core 6.0 is still supported, so there are often many times when you want to refer to its documentation. In such cases, if you refer to the latest ASP.NET Core 8.0 documentation, you will likely find significant differences.
It's nothing if you know it, but since it has been a topic of discussion regarding Microsoft Learn, I will note it just in case.

Scenario

https://learn.microsoft.com/ja-jp/aspnet/core/blazor/security/webassembly/?view=aspnetcore-8.0?WT.mc_id=DT-MVP-5004827

I want to implement Entra ID authentication for ASP.NET Core 6.0 Blazor WebAssembly with ASP.NET Core Hosted!
However, since the ASP.NET Core Hosted template has been removed in .NET 8, information about ASP.NET Core Hosted authentication is naturally not written in that documentation either.
Moreover, since it's about ASP.NET Core 6.0 Blazor WebAssembly, I want to refer to the 6.0 documentation!

Solution

Select 6.0 from the ASP.NET Core 8.0 combo box.

Then, you will see a heading for hosting with Entra ID.

That's wonderful.
From the heading, I have arrived at the documentation I was looking for.
