Services.AddOptions()含糊不清

Question

我正在忙着将我们的ASP.NET Core API从RC1迁移到RC2.

RC2要求我们在使用时配置以下内容IOptions<T>:

services.AddOptions();

但是我得到以下编译错误:

错误CS0121呼叫是下列方法或属性之间暧昧:"Microsoft.Extensions.DependencyInjection.OptionsServiceCollectionExtensions.AddOptions(Microsoft.Extensions.DependencyInjection.IServiceCollection)"和"Microsoft.Extensions.DependencyInjection.OptionsServiceCollectionExtensions.AddOptions(Microsoft.Extensions.DependencyInjection .IServiceCollection)'TransitApi.Api..NET Framework 4.5.2

这些是完全相同的扩展方法!我已经尝试删除所有软件包并删除锁定文件,但无济于事.

检查项目内“参考”下的依赖项。

您的依赖项之一是获取旧库，我怀疑它"WindowsAzure.Storage": "7.0.0"似乎是它的唯一候选者。根据 GitHub 项目页面，我认为7.0.2预览版本已经准备就绪，请尝试一下。rc2-final
