从 Visual Studio 运行我的项目时出现以下异常，它是一个 ASP.NET Core 项目。

似乎依赖项注册了两次，因此“System.ArgumentException：已添加具有相同键的项目”。

它似乎也与路线有关，但我找不到调试它的方法。

它似乎也与 Api 中的版本控制有关，因为如果我删除此代码，异常就会消失。

services.AddApiVersioning(o =>
        {
            o.AssumeDefaultVersionWhenUnspecified = true;
            o.DefaultApiVersion = new ApiVersion(1, 0);
            o.ReportApiVersions = true;
            o.ApiVersionSelector = new CurrentImplementationApiVersionSelector(o);
        });

任何人都见过这个或知道如何调试它。

尝试添加此代码：

services.AddMvcCore().AddVersionedApiExplorer(
                opt =>
                {
                    opt.GroupNameFormat = "'v'VVV";

                    opt.SubstituteApiVersionInUrl = true;
                });
