Question

我正在尝试在我的WebApi项目中使用Ninject。

let kernel = new StandardKernel()
kernel.Bind<ITestDomain>().To<TestDomain>() |> ignore

let (resolver:Dependencies.IDependencyResolver) = upcast new NinjectDependencyResolver(kernel)
GlobalConfiguration.Configuration.DependencyResolver <- resolver

我最终收到此错误：

 {
          "message":"An error has occurred.",
          "exceptionMessage":"Error activating IFilterProvider using binding 
          from IFilterProvider to DefaultFilterProvider\r\nA  cyclical

          not declared a dependency for IFilterProvider on any 
          implementations of the service.\r\n  2) Consider combining the 
          services into a single one to remove the cycle.\r\n  3) Use 
          property injection instead of constructor injection, and implement 
          IInitializable\r\n     if you need initialization logic to be run 
          after property values have been injected.\r\n",
