Support async extension methods on IQuerayble

[kichalla]

I am using InMemory store where I use the "SingleOrDefaultAsync" api to retrieve an item…I am noticing that even though the item with the given id is present, it is not retrieving it…the sync version “SingleOrDefault” retrieves it fine…

// GET api/suggestions/5
public async Task<IActionResult> Get(int id)
{
    Suggestion suggestion = await dataContext.Suggestions.SingleOrDefaultAsync(sug => sug.Id == id);
    if (suggestion == null)
    {
        return new CustomHttpStatusCodeResult(404);
    }

    return new CustomJsonResult(suggestion);
}

It seems this is a known issue...creating issue for tracking...

Assigned to Andrew who already mentioned he will be looking at this.

@weitzhandler EF7 defines and support several async extension methods for IQueryable (see https://github.com/aspnet/EntityFramework/blob/dev/src/EntityFramework.Core/Extensions/EntityFrameworkQueryableExtensions.cs). Is there anything you are missing there or that you have found isn't working correctly?

In case you are asking for the support for async operators over IQueryable to become more first class as opposed to an EF extension, it might help to file an issue at https://github.com/dotnet/corefx.
