Html.RenderPartial giving me strange overload error?

I made a test partial page named _Test.cshtml and put it in the same directory as my view that will be calling it, here it is:

<div>hi</div>

And in the calling cshtml view, I simply put:

@Html.RenderPartial("_Test")

Which gives me the error:

> CS1502: The best overloaded method > match for > 'System.Web.WebPages.WebPageExecutingBase.Write(System.Web.WebPages.HelperResult)' > has some invalid arguments

I have also tried the full path with the same result.

I am very confused as to why this is acting this way, I assume I am missing something simple?

You are getting this error because Html.RenderXXX helpers return void - they have nothing to return because they are writing stuff directly* to response. You should use them like this:

@{ Html.RenderPartial("_Test"); }

There is also Html.Partial helper, which will work with your syntax, but I'd not recommend using it unless you have to, because of performance (it first composes given partial view into string, and then parent view puts it into response*).

* this is not entirely true, they are actually being rendered into ViewContext.Writer and once whole page is rendered and composed, the whole thing goes to response
