Question

在我们的MvxApplication中，我使用EndingWith方法注册我们的存储库。

我在一个不同的项目中使用了这种方法，我们的App.cs和我们的存储库位于同一个项目中，一切正常。现在我已将App.cs移动到一个单独的项目中，MvvmCross IOC不会从我们的核心应用程序注册依赖项。

初始化方法

public override void Initialize() {

    // stuff happens here

    // Register all repositories
    CreatableTypes().EndingWith("Repository").AsInterfaces().RegisterAsLazySingleton();

    // more stuff happens here

    // Resolve the DbVersionRepo to run migrations.
    // This line is breaking
    var databaseVersionRepository = MvxSimpleIoCContainer.Instance.Resolve < IDatabaseVersionRepository > ();

}

有问题的资料库

public class DatabaseVersionRepository : RepositoryBase, IDatabaseVersionRepository
{ 
    // do stuff
}

例外

项目结构是这样的。

OurCompany.AppCore
    \ Repositories
        \IDatabaseVersionRepository.cs
        \DatabaseVersionRepository.cs

OurCompany.CustomApp.Core
    \ App.cs

OurCompany.CustomApp.Droid.Ui
    \ Setup.cs

我还应该注意到我尝试了这种方法但得到了相同的结果。

CreatableTypes().Inherits<IDatabaseVersionRepository>().AsInterfaces().RegisterAsLazySingleton();

根据Stuart上面的评论，解决当前程序集之外的依赖关系的方法是执行以下操作。

typeof(RepositoryBase).Assembly
                      .CreatableTypes()
                      .EndingWith("Repository")
                      .AsInterfaces()
                      .RegisterAsLazySingleton();
