Servicestack测试:未找到方法：'Int32 Int32

Question

试图在ServiceStack中构建与db连接的集成测试。我的ServiceStack应用程序运行良好，但是当我运行简单测试时，我得到了如下错误消息:22

System.MissingMethodException：‘方法找不到：'Int32 ServiceStack.DataAnnotations.CustomFieldAttribute.get_Order()'.'’

这里有一种小鳕鱼：

using ServiceStack;
using ServiceStack.OrmLite;
using ServiceStack.Data;
using NUnit.Framework;
using ServiceStack.DataAnnotations;
using System.Collections.Generic;

namespace oth.Tests.IntegrationTests
{
    public class AppHost2 : AppSelfHostBase
    {
        public AppHost2() : base("Customer REST Example", typeof(CustomerService).Assembly) { }

        public override void Configure(Container container)
        {
            var connectionString =  "Host=localhost;Port=5432;Database=test_1234;Username=postgres;Password=local";
            container.Register<IDbConnectionFactory>(c =>
                new OrmLiteConnectionFactory(connectionString, PostgreSqlDialect.Provider));

            using var db = container.Resolve<IDbConnectionFactory>().Open();
            db.CreateTableIfNotExists<Customer>();
        }
    }

    public class Customer
    {
        [AutoIncrement]
        public int Id { get; set; }

        public string Name { get; set; }
    }

    public class GetCustomers : IReturn<GetCustomersResponse> { }
    public class GetCustomersResponse
    {
        public List<Customer> Results { get; set; }
    }


    public class CustomerService : Service
    {
        public object Get(GetCustomers request)
        {
            return new GetCustomersResponse { Results = Db.Select<Customer>() };
        }
    }

    public class CustomerRestExample
    {
        const string BaseUri = "http://localhost:2000/";
        ServiceStackHost appHost;

        public CustomerRestExample()
        {
            //Start your AppHost on TestFixture SetUp
            appHost = new AppHost2()
                .Init()
                .Start(BaseUri);
        }

        [OneTimeTearDown]
        public void OneTimeTearDown() => appHost.Dispose();

        /* Write your Integration Tests against the self-host instance */

        [Test]
        public void Run_Customer_REST_Example()
        {
            var client = new JsonServiceClient(BaseUri);

            var all = client.Get(new GetCustomers());
            Assert.That(all.Results.Count, Is.EqualTo(0));
        }
    }
}

每当您看到缺少类型的或缺少的方法异常时，使用MyGet预发布包就意味着安装很脏(即使用来自不同构建时间的预发布包)。

在这种情况下，您需要清除Nuget包缓存并再次下载最新的包，这将确保您的所有包都来自最新的相同构建：

$ dotnet nuget locals all -clear
