asp.net mvc 核心 以下方法或属性之间的调用不明确:

我正在处理一个应用程序，我在 Startup.cs 部分类中遇到错误，我找不到为什么会出现此错误：

调用在以下方法或属性之间不明确：Microsoft.Extensions.DependencyInjection.OptionsServiceCollectionExtensions.Configure（Microsoft.Extensions.DependencyInjection.IServiceCollection， System.Action）Microsoft.Extensions.DependencyInjection.OptionsServiceCollectionExtensions.Configure（Microsoft.Extensions.DependencyInjection.IServiceCollection， System.Action）

我的两个部分启动.cs类是

错误在这里：
