TypeInitializationException: инициализатор типа для 'System.Data.Entity.Internal.AppConfig' вызвал исключение

/ 26 декабря 2018

В настоящее время я пытаюсь создать ASP.NET Core API для приложения под названием «Приложение».Он содержит клиентов и продукты.Когда я делаю запрос на получение всех клиентов через мой CustomerController, я получаю следующую ошибку:

System.TypeInitializationException HResult = 0x80131534 Сообщение = Инициализатор типа для 'System.Data.Entity.Internal.AppConfig'бросил исключение.Source = EntityFramework StackTrace: в System.Data.Entity.Internal.LazyInternalConnection..ctor (контекст DbContext, String nameOrConnectionString) в System.Data.Entity.DbContext..ctor (String nameOrConnectionString) в Application.TestAPI.Logic.Dxt.App...ctor (String connString) в C: \ Users \ Chris \ Source \ repos \ Application.TestAPI \ Application.TestAPI.Logic \ Database \ ApplicationDatabaseContext.cs: строка 9 в Application.TestAPI.Logic.Init. <> c__DisplayClass0_0.b__0 (IServiceProvider _) в C: \ Users \ Chris \ Source \ repos \ Application.TestAPI \ Application.TestAPI.Logic \ Init.cs: строка 19 в Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitFactory (FactoryCallSiteScopePiderScopePiderScopePiderScopePiderScopePiderScopePiderScopePiderScopePiderScopePiderScopePiderScopeSiderScopeCallScopePiderScopePiderScopeSiteScopePiderSourceSCriceCenterScopeSiderScopeCallScopeSiderScopeCallScopeSiderScopeCiteScopeSiderScopeCallScopeSiderScopeCallScopeSiderScopeCenterScopeSiderScopeCallScopeSiderScopeCricePecerSiderSCallSiderScopePCenterSiteScopePecerSiderCallScopeSiderSCriceCriceCroneServiceSiderSCallScopePerviceCallScopeSiderCallSider фабрикаCallC)область) в Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteVisitor 2.VisitCallSite(IServiceCallSite callSite, TArgument argument) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitScoped(ScopedCallSite scopedCallSite, ServiceProviderEngineScope scope) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteVisitor 2.VisitCallSite (IServiceCallSite callSite, аргумент TArgument) в Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitConstructили (ConstructorCallSite constructorCallSite, ServiceProviderEngineScope scope) в Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteVisitor 2.VisitCallSite(IServiceCallSite callSite, TArgument argument) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitScoped(ScopedCallSite scopedCallSite, ServiceProviderEngineScope scope) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteVisitor 2.VisitCallSite (IServiceCallSite, callSite, аргумент TArgument) в scope.в Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteVisitor 2.VisitCallSite(IServiceCallSite callSite, TArgument argument) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitScoped(ScopedCallSite scopedCallSite, ServiceProviderEngineScope scope) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteVisitor 2.VisitCallSite (IServiceCallSite callSite, аргумент TArgument) в Microsoft.Extensions.DependencyInjection.ServiceLookup.DynamicServiceProviderEngine .Exjection.Inc.ServiceLookup.ServiceProviderEngine.GetService (Тип serviceType, ServiceProviderEngineScope serviceProviderEngineScope) в Microsoft.Extensions.DependencyInjection.ServiceLookup.ServiceProviderEngineScope.GetService (Тип serviceType) в MicrosoftdencyExjec.tion.ActivatorUtilities.GetService (IServiceProvider зр, тип тип, тип requiredBy, булева isDefaultParameterRequired) при Microsoft.AspNetCore.Mvc.Controllers.ControllerActivatorProvider. <> c__DisplayClass4_0.b__0 (ControllerContext controllerContext) при Microsoft.AspNetCore.Mvc.Controllers.ControllerFactoryProvider. <> c__DisplayClass5_0.g__CreateController | 0 (ControllerContext controllerContext) в Microsoft.AspNetCore.Mvc.Internal.ControllerActionInvoker.Next (State & next, Scope & scope, Object & state, Boolean & isCompleted) в Microsoft.AspNetCternalInrol.Conv.Внутреннее исключение 1: FileNotFoundException: не удалось загрузить файл или сборку 'System.Configuration.ConfigurationManager, версия = 0.0.0.0, культура = нейтральная, PublicKeyToken = cc7b13ffcd2ddd51'.Det går inte att hitta filen.

Код / класс, в котором происходит сбой: 

using Application.TestAPI.Logic.Models;
using System.Data.Entity;
using System.Diagnostics;

namespace Application.TestAPI.Logic.Database
{
    public class ApplicationDatabaseContext : DbContext
    {
        public ApplicationDatabaseContext(string connString) : base(connString)
        {
           //Database.Log = s => Debug.WriteLine(s);
        }

    public DbSet<ApplicationCustomer> Customers { get; set; }
    public DbSet<ApplicationContract> Contracts { get; set; }
    }
}

Строка подключения находится не в моем App.config для библиотеки классов, а вмой appsettings.json в API-проекте.

Параметр connString является допустимой строкой соединения, которая, как мне известно, работает и передается из следующей строки кода: 

services.AddScoped(_ => new ApplicationDatabaseContext(applicationConfiguration.GetValue<string>("ConnectionString")));

My * .csproj-файл выглядит следующим образом:

Я попытался изменить структуру моего App.config, переустановить EntityFramework, жестко запрограммировать строку подключения и установить System.Configuration.ConfigurationManager через NuGet.Пока ничего не получалось.

Любые предложения / объяснения, что может быть причиной этого?

С уважением,

Крис
