protected async void Page_Load(object sender, EventArgs e)
{
   Response.Write(await FunctionStringAsync("name"));
}

Above one is Working for me but, I want to use inside Razor like 

<%=(await FunctionStringAsync("name"))%>
or
@(await FunctionStringAsync("name"))

I am getting

warning CS1998: This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.

error CS4033: The 'await' operator can only be used within an async method. Consider marking this method with the 'async' modifier and changing its return type to 'Task'.

    You can't, and you shouldn't want to. Ensure that your view model contains all data that you wish to display. – CodeCaster Jan 11 '16 at 11:07
  • Dear @CodeCaster, Why not? Is it documented anywhere? As i think if we can explicitly mark page_load as async then why not control rendering? Using client script and achieve target by loading once inside controller or page_load is different thing. In my case i am using multiple if else in side razor and create tags dynamically, I don't want to repeat if else inside controller and razor again. – Raj kumar Jan 13 '16 at 10:35
  • You cannot mark a view async, period. Razor gets compiled to a C# class that is executed, and async is not supported in it. You should not even want to use async in a view. If you need it, it's a sign that you're doing too much heavy work in the view. – CodeCaster Jan 13 '16 at 10:55
