在 .NET 6 上調(diào)試.NET 5 的Web應(yīng)用程序出現(xiàn)程序閃退問(wèn)題

首先看了下本地 .NET 的環(huán)境

?  ~ dotnet --list-sdks
6.0.200 [/usr/local/share/dotnet/sdk]
?  ~ dotnet --list-runtimes
Microsoft.AspNetCore.App 6.0.2 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 6.0.2 [/usr/local/share/dotnet/shared/Microsoft.NETCore.App]

本地只有 .NET 6 的SDK 和 runtimes 環(huán)境，.NET 6 對(duì) .NET 5 是兼容的, 需要在 .csproj 文件中做如下配置：

  <PropertyGroup>
    <RollForward>Major</RollForward>
  </PropertyGroup>

如果不這樣配置的話會(huì)報(bào)如下錯(cuò)誤：

使用 /Users/morris/Desktop/net5.0/TaskSystem/Properties/launchSettings.json 中的啟動(dòng)設(shè)置 [配置文件TaskSystem]...
It was not possible to find any compatible framework version
The framework 'Microsoft.AspNetCore.App', version '5.0.0' (arm64) was not found.
  - The following frameworks were found:
      6.0.2 at [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.App]

You can resolve the problem by installing the specified framework and/or SDK.

The specified framework can be found at:
  - https://aka.ms/dotnet-core-applaunch?framework=Microsoft.AspNetCore.App&framework_version=5.0.0&arch=arm64&rid=osx.12-arm64
目標(biāo)進(jìn)程已退出，但未引發(fā) CoreCLR 啟動(dòng)事件。請(qǐng)確保將目標(biāo)進(jìn)程配置為使用 .NET Core。如果目標(biāo)進(jìn)程未運(yùn)行 .NET Core，則發(fā)生這種情況并不意外。
程序“[25227] TaskSystem.dll”已退出，代碼為 150 (0x96)。

另外，如果是Windows的話，直接再裝一套 .NET 5 也可以解決此問(wèn)題。
