找不到任何兼容的框架版本找不到框架“Microsoft.NETCore.App”，版本“2.2.8”

Question

我正在尝试从我的 Visual Studio 2019 实例运行简单的 .net core 2.2 api 项目，此错误不断出现：The specified version of Microsoft.NetCore.App or Microsoft.AspNetCore.App was not found. It was not possible to find any compatible framework version The framework 'Microsoft.NETCore.App', version '2.2.8' was not found。

我检查了安装在我的机器上的 .net 核心运行时，如下所示：
