您可能更新了ASP.NET Core依赖项，但仍使用过时的AutoMapper.Extensions.Microsoft.DependencyInjection包.

You likely updated your ASP.NET Core dependencies, but still using outdated AutoMapper.Extensions.Microsoft.DependencyInjection package.

对于ASP.NET Core，您至少需要3.0.1 > https://www.nuget.org/packages/AutoMapper.Extensions.Microsoft.DependencyInjection/3.0.1

For ASP.NET Core you need at least Version 3.0.1 from https://www.nuget.org/packages/AutoMapper.Extensions.Microsoft.DependencyInjection/3.0.1

哪个引用了AutoMapper 6.1.1或更高版本.

Which references AutoMapper 6.1.1 or higher.

AutoMapper(> = 6.1.1)

AutoMapper (>= 6.1.1)

Microsoft.Extensions.DependencyInjection.Abstractions(> = 2.0.0)

Microsoft.Extensions.DependencyInjection.Abstractions (>= 2.0.0)

Microsoft.Extensions.DependencyModel(> = 2.0.0)

Microsoft.Extensions.DependencyModel (>= 2.0.0)

较早的软件包取决于Microsoft.Extensions.DependencyInjection.Abstractions 1.1.0，因此不能与ASP.NET Core一起使用，因为Microsoft.Extensions.DependencyInjection.Abstractions 1.1.0和2.0

The older packages depend on Microsoft.Extensions.DependencyInjection.Abstractions 1.1.0 and can't be used with ASP.NET Core since there have been breaking changes between Microsoft.Extensions.DependencyInjection.Abstractions 1.1.0 and 2.0
