asp.net mvc core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，我无法找到为什么会出现此错误：

以下方法或属性之间的调用不明确：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Startup.cs类是

using Microsoft.Extensions.DependencyInjection; using System.Security.Claims; using Microsoft.AspNetCore.Http; using Microsoft.Extensions.Configuration; namespace GiftUWish.WebAPI { public partial class Startup { private void SetServices(IServiceCollection services) { //PROFILE service and repository services.AddScoped(); services.AddScoped(); ////GIFT service and repository services.AddScoped(); services.AddScoped(); //EVENT service and repository services.AddScoped(); services.AddScoped(); //CREDIT CARD INFORMATION serice and repository services.AddScoped(); services.AddScoped(); //CHIPPED IN serive and repository services.AddScoped(); services.AddScoped(); //UNIT OF WORK services.AddScoped(); //Authentication-Token , Header which contains information about user from Identity Server services.AddTransient(s => s.GetService().HttpContext.User); //Facebook Graph API services.AddScoped(); //Setup configuration settings form appsettings.json services.Configure(Configuration.GetSection("Facebook")); services.Configure(Configuration.GetSection("Paiment:BrainTree")); services.Configure(Configuration.GetSection("Paiment:PayPal:PayPalAdaptivePaymentsAPI")); services.Configure(Configuration.GetSection("Paiment:PayPal:PayPalNonAdaptivePaymentsAPI")); services.Configure(Configuration.GetSection("Paiment:PayPal:PayPalPayFlow")); services.AddSingleton(Configuration); } } } using Microsoft.AspNetCore.Authentication.Cookies; using Microsoft.AspNetCore.Builder; using Microsoft.AspNetCore.Hosting; using Microsoft.AspNetCore.Http; using Microsoft.AspNetCore.Mvc; using Microsoft.Extensions.Configuration; using Microsoft.Extensions.DependencyInjection; using Microsoft.Extensions.Logging; using Newtonsoft.Json.Serialization; using System.Threading.Tasks; namespace GiftUWish.WebAPI { public partial class Startup { public static IConfiguration Configuration { get; set; } private readonly string Audience = "https://localhost:44362/"; public Startup(IHostingEnvironment env) { var builder = new ConfigurationBuilder() .SetBasePath(env.ContentRootPath) .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true) .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true) .AddEnvironmentVariables(); Configuration = builder.Build(); } // This method gets called by the runtime. Use this method to add services to the container. public void ConfigureServices(IServiceCollection services) { // Add framework services. services .AddMvc(options => { options.Filters.Add(new RequireHttpsAttribute()); }) .AddJsonOptions(options => { options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); }); services.Configure(options => { options.Events = new CookieAuthenticationEvents() { OnRedirectToLogin = ctx => { if (ctx.Request.Path.StartsWithSegments("/api") && ctx.Response.StatusCode == 200) { ctx.Response.StatusCode = (int)System.Net.HttpStatusCode.Unauthorized; return Task.FromResult(null); } else { ctx.Response.Redirect(ctx.RedirectUri); return Task.FromResult(null); } } }; }); //Add DI and other services SetServices(services); } // This method gets called by the runtime.

Project.json依赖项

“dependencies”：{“Braintree”：“2.61.0”，“Microsoft.AspNet.Mvc.Core”：“6.0.0-rc1-final”，“Microsoft.AspNetCore.Diagnostics”：“1.0.0”，“ Microsoft.AspNetCore.Identity“：”1.0.0“，”Microsoft.AspNetCore.Mvc“：”1.0.0“，”Microsoft.AspNetCore.Server.IISIntegration“：”1.0.0“，”Microsoft.AspNetCore.Server。 Kestrel“：”1.0.0“，”Microsoft.Extensions.Configuration.EnvironmentVariables“：”1.0.0“，”Microsoft.Extensions.Configuration.FileExtensions“：”1.0.0“，”Microsoft.Extensions.Configuration.Json“ ：“1.0.0”，“Microsoft.Extensions.Logging”：“1.0.0”，“Microsoft.Extensions.Logging.Console”：“1.0.0”，“Microsoft.Extensions.Logging.Debug”：“1.0。 0“，”Microsoft.Extensions.Options“：”1.0.0“，”Microsoft.Extensions.Options.ConfigurationExtensions“：”1.0.0“，”Microsoft.IdentityModel.Tokens“：”5.0.0“，”Microsoft。 Owin.Security.Cookies“：”3.0.1“，”Microsoft.Owin.Security.OAuth“：”3.0.1“，”Newtonsoft.Json“：”9.0.1“，”PayPal“：”1.7.3“ ，“PayPalAdaptiveAccountsSDK”：“2.9.110”，“PayPalAdaptivePaymentsSDK”：“2.15.117”，“P ayPalCoreSDK“：”1.7.1“，”PayPalMerchantSDK“：”2.16.117“，”System.IdentityModel.Tokens.Jwt“：”5.0.0“}，

错误在这里：

 services.Configure(Configuration.GetSection("Facebook")); services.Configure(Configuration.GetSection("Paiment:BrainTree")); services.Configure(Configuration.GetSection("Paiment:PayPal:PayPalAdaptivePaymentsAPI")); services.Configure(Configuration.GetSection("Paiment:PayPal:PayPalNonAdaptivePaymentsAPI")); services.Configure(Configuration.GetSection("Paiment:PayPal:PayPalPayFlow")); 

日Thnx

Answer 1

这是因为您正在混合软件包版本 – 您将rc1（ Microsoft.AspNet.Mvc.Core": "6.0.0-rc1-final" ）与1.0.0混合在一起。将所有内容移至1.0.0。
