Aspnet- could生成器找不到.NET 5

Question

我正在尝试搭建.NET身份文件，如下所示：

https://docs.microsoft.com/en-us/aspnet/core/security/authentication/scaffold-identity?view=aspnetcore-5.0&tabs=netcore-cli#scaffold-identity-into-an-mvc-project-with-authorization

问题是，当我运行'aspnet-codegenerator‘命令时，它显示了这个错误：

It was not possible to find any compatible framework version
The framework 'Microsoft.NETCore.App', version '5.0.0-rc.2.20475.5' was not found.
- The following frameworks were found:
  3.1.10 at [/usr/share/dotnet/shared/Microsoft.NETCore.App]

我已经安装了.NET 5：

dotnet-sdk.dotnet --version
5.0.100

有什么解决方案吗？

Answer 1

作为建议，您可以在解决方案所在的目录中创建一个名为"global.json“的文件，并按如下方式执行其内容；

{
  "sdk": {
    "version": "5.0.100",
    "rollForward": "latestFeature"
  }
}
