无法调试启动我的.NET 6 ASP.NET项目-加载ASP.NET核心运行时失败
无法调试启动我的.NET 6 ASP.NET项目-加载ASP.NET核心运行时失败
提问于 2022-08-25 00:48:25
当我使用VisualStudio2022使用ASP.NET核心空模板创建一个新项目时，我在新项目向导的一个步骤中从.NET下拉列表中选择.NET 6.0 (长期支持)。项目成功构建。
当我使用IIS和Edge去调试运行项目时，它会出现并显示消息
HTTP Error 500.31 - Failed to load ASP.NET Core runtime

这几乎证实，我可能没有安装FW 6。因此，我尝试使用下面的CL命令来验证这一点
dotnet --info而且，从我的阅读方式来看，它表明我确实安装了它。

Y:\>如果我没有安装这个版本的FW，我不希望向导会把它呈现给我。
但问题仍然是，如果我安装了它，问题是什么？框架有不同的安装类型吗？例如，运行时和SDK，或者类似的东西？我现在不确定下一步该去哪里.

根据错误消息，它说Microsoft.NetCore.App 6.0.8没有安装，我发现您只是安装了Microsoft.AspNetCore.App 6.0.8，我建议您尝试安装它，然后再试一次。
