Use of await in Razor views

Question

Is it possible to await on tasks in Razor .cshtml views?

By default it complains that it can only be used in methods marked with async so I

Answer 1

I know this is an older thread, but I'll add my input just in case someone else finds it useful. I ran into this problem working with the new MongoDB driver in ASP.Net MVC - the new driver (for now), only implements async methods and returns async cursors, which can't be used in a foreach because asynccursor doesn't implement IEnumerable. The sample code typically looks like:

while(await cursor.movenextasync)
    var batch=cursor.current
    foreach(var item in batch)
        --do stuff here--

But, this doesn't work in razor, because views are inherently not async, and await doesn't cut it.

I got it to work by changing the first line to:

while(cursor.MoveNextAsync().Result)

which returns true until the cursor hits the last entry.

Hope that helps!
