ConfigureServices 中的 IConfiguration 错误

Question

当我添加配置时，像这样：

services.Configure<JiraOptions>(Configuration.GetSection("Jira"));

我的IDE高亮了IConfiguration中的错误：

Ambiguous reference: AutoMapper.Configuration.IConfiguration Microsoft.Extensions.Configuration.IConfiguration match

当我尝试调用方法 GetSection 时，它写入错误：

Ambiguous invocation: Microsoft.Extensions.DependencyInjection.IServiceCollection Configure<JiraOptions>(this Microsoft.Extensions.DependencyInjection.IServiceCollection, Microsoft.Extensions.Configuration.IConfiguration) (in class OptionsConfigurationServiceCollectionExtensions) Microsoft.Extensions.DependencyInjection.IServiceCollection Configure<JiraOptions>(this Microsoft.Extensions.DependencyInjection.IServiceCollection, System.Action<Grafana.Domain.JiraOptions>) (in class OptionsServiceCollectionExtensions) match

我该如何解决？完整代码和屏幕：

using System.Reflection;
using System.Threading.Tasks;
using AutoMapper;
using AutoMapper.Configuration;
using Grafana.Data;
using Grafana.Data.Interfaces;
using Grafana.Domain;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddAutoMapper(Assembly.GetExecutingAssembly());

        services.AddMvc();
        services.AddControllers();

        services.AddTransient<IJiraClient, JiraClient>();
        services.AddTransient<IBugsMonitoringService, BugsMonitoringService>();

        services.Configure<JiraOptions>(Configuration.GetSection("Jira"));
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseRouting();

        app.UseEndpoints(endpoints => { endpoints.MapControllers(); });
    }
}

选项：

public class JiraOptions
{
    public string Url { get; set; }

    public string Login { get; set; }

    public string Password { get; set; }
}

您使用的两个命名空间 AutoMapper.Configuration 和 Microsoft.Extensions.Configuration 都提供 IConfiguration 接口，这会导致歧义和冲突。从 usings 中删除两个命名空间中的一个（最好 AutoMapper.Configuration），一切都会好起来的。
