Hello, I render a template to a request by ajax post, I get the following exception System.ArgumentOutOfRangeException in line view.RenderAsync (ViewContext) .GetAwaiter () GetResult ().;

Thanks for the code. I wish you would have referenced aspnet/Mvc#3091 and https://github.com/aspnet/Entropy/blob/dev/samples/Mvc.RenderViewToString/RazorViewToStringRenderer.cs where I assume the code is from.

I just wana say thnx to anybody who worked on this.

THAAAAAAAAAAAAAAAAAAAAAAAAANKS
