+Starting with .NET 9, the official team has introduced the `AppHostRelativeDotNet` mechanism, which fully encompasses all the functionality provided by this library. For more details, please refer to: https://github.com/dotnet/runtime/issues/64430
+
+After upgrading to .NET 9, you can modify your `.csproj` file as shown in the example below to enable support for locating the .NET runtime via relative paths:
+
+```xml
+<Project Sdk="Microsoft.NET.Sdk">
+
+  <PropertyGroup>
+    <OutputType>Exe</OutputType>
+    <TargetFramework>net9.0</TargetFramework>
+    <ImplicitUsings>enable</ImplicitUsings>
+    <Nullable>enable</Nullable>
+    <AppHostDotNetSearch>AppRelative;Global;</AppHostDotNetSearch>
+    <AppHostRelativeDotNet>../relative/path/to/runtime</AppHostRelativeDotNet>
+  </PropertyGroup>
+
+</Project>
+```
+
+**Note:** After publishing your application, you will need to place the .NET runtime files in a folder located at `../relative/path/to/runtime`. You can extract these runtime files from the .NET SDK, locate them in your NuGet package cache, or download and unzip the runtime files from the official .NET website.
+
+Since all features of this repository have been integrated into .NET 9, this repository will be archived.

+
+在 dotnet 9 时，官方已经添加了 AppHostRelativeDotNet 机制，完全包含了本库提供的所有功能。详细请参阅：https://github.com/dotnet/runtime/issues/64430
+
+更新到 .NET 9 之后，可更改 csproj 代码为如下示例内容，从而获取寻找相对路径的 dotnet runtime 能力
+
+```xml
+<Project Sdk="Microsoft.NET.Sdk">
+
+  <PropertyGroup>
+    <OutputType>Exe</OutputType>
+    <TargetFramework>net9.0</TargetFramework>
+    <ImplicitUsings>enable</ImplicitUsings>
+    <Nullable>enable</Nullable>
+    <AppHostDotNetSearch>AppRelative;Global;</AppHostDotNetSearch>
+    <AppHostRelativeDotNet>../relative/path/to/runtime</AppHostRelativeDotNet>
+  </PropertyGroup>
+
+</Project>
+```
+
+注： 你需要在发布之后，在相对路径为 `../relative/path/to/runtime` 的文件夹里放入 dotnet runtime 的文件。你可以从 dotnet SDK 里面提取 dotnet runtime 的文件，或者从你的 NuGet 包缓存里面查找，或者从 dotnet 官方下载运行时 zip 包解压缩
+
+详细请参阅 [dotnet 9 通过 AppHostRelativeDotNet 指定自定义的运行时路径](https://blog.lindexi.com/post/dotnet-9-%E9%80%9A%E8%BF%87-AppHostRelativeDotNet-%E6%8C%87%E5%AE%9A%E8%87%AA%E5%AE%9A%E4%B9%89%E7%9A%84%E8%BF%90%E8%A1%8C%E6%97%B6%E8%B7%AF%E5%BE%84.html )
+
+由于本代码仓库所有功能已经被 .NET 9 引入，本仓库将归档
