Model problem in RenderViewToString<TModel>(string name, TModel model) method

[seriouz]

You can't pass a model (e.g.: List<>()) to the RenderViewToString<TModel>(string name, TModel model) method. When you do it, an exception is thrown:

fail: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[0]
      An unhandled exception has occurred while executing the request
System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Seems Rono has the same problem like me http://stackoverflow.com/questions/39776009/render-a-razor-view-containing-a-url-to-a-string-in-asp-net-core

Hi, this issue is being closed because this repo contains only unofficial samples and tests, and is not otherwise regularly maintained. If you're having an issue with ASP.NET Core or EF Core, please log a new issue in the appropriate product repo (or if you're not sure where, the https://github.com/aspnet/Home/issues repo).

For anyone else landing on this page from Google, if you have an HttpContext then you can use the stackoverflow solution posted by seriouz. If you don't have an HttpContext (e.g. you're running from a command line application) then you can use this version: https://github.com/waf/RazorToStringExample/blob/master/RazorToStringExample/Services/RazorViewToStringRenderer.cs
