我在设置依赖关系解析器时收到此错误.

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.

我在这里错过了什么？

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,我已经拥有了所有必需程序集的最新版本,而且我仍然遇到此错误.

解决方法

已安装软件包,但显然有些引用来自GAC而不是来自NuGet软件包文件夹.

这些都是手动删除的,我在packages文件夹中添加了引用并且它有效.

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