c# - MVC6 ViewComponents Simple Example results in "Could not find an 'Invoke' method matching the parameters." -

i trying figure out new viewcomponents feature in simplest sense , having trouble , lack of documentation not helping.

my first goal invoke viewcomponent list of strings , have them displayed.

the literally guide can find viewcomponents here , have based off of far: http://www.asp.net/vnext/overview/aspnet-vnext/vc#intro

i want display list of strings pass in invoke method, can't seem invoke method work in first place.

my folder/file structure is:

my simple code follows:

vcexampleviewcomponent.cs

using microsoft.aspnet.mvc;  namespace mvc6example3.viewcomponents {     public class vcexampleviewcomponent : viewcomponent     {         public vcexampleviewcomponent()         {          }          public iviewcomponentresult invoke(string[] strarr)         {             return view(strarr);         }     } } 

default.cshtml (what viewcomponent supposed rendering)

@model string[]  <h3>strings passed in:</h3> @foreach (string str in model) {     <span>@str</span> } 

index.cshtml (where viewcomponent invoked)

@{     viewbag.title = "home page"; }  <div class="jumbotron">     <h1>viewcomponent example</h1> </div>  @component.invoke("vcexample", new string[]{"hello", "hola", "bonjour" }) 

the error is:

500 internal server error
