services.AddBootstrapCss();
services.AddScoped<ILoggerRepository, LoggerRepository>();

我的IDE抱怨AddBootstrapCss

Severity    Code    Description Project File    Line    Suppression State
Error   CS1061  'IServiceCollection' does not contain a definition for 'AddBootstrapCss' and no accessible extension method 'AddBootstrapCss' accepting a first argument of type 'IServiceCollection' could be found (are you missing a using directive or an assembly reference?)

这是一个.NET Core 5到.NET Core 6的升级，所以我不确定这个替换会是什么。
