asp.net-web-api - GlobalConfiguration - 尝试访问字段 '<>9__CachedAnonymousMethodDelegate2' 失败

Question

我在设置依赖关系解析器时收到此错误。

代码:

GlobalConfiguration.Configuration.DependencyResolver = new UnityDependencyResolver(container);

错误:

Attempt by method 'System.Web.Http.GlobalConfiguration..cctor()' to access field 'System.Web.Http.GlobalConfiguration.CS$<>9__CachedAnonymousMethodDelegate2' failed.

我在这里缺少什么？

发布的所有解决方案都涉及安装最新版本的 Microsoft.AspNet.WebApi。

Install-Package Microsoft.AspNet.WebApi -IncludePrerelease

但是，我已经拥有所需程序集的所有最新版本，但仍然收到此错误。

Answer 1

软件包已安装，但显然一些引用是从 GAC 而不是从 NuGet 软件包文件夹中获取的。

这些已手动删除，我在包文件夹中添加了引用并且它起作用了。

(应该有一个 NuGet 功能来“清理”引用，以便它们从包文件夹而不是其他地方获取。)
