Asp.Net MVC 4 Async controllers

[AnthonySteele]

Asp.Net MVC 4 in VS2012 allows controller action to methods return async Task instead of ActionResult. Spark appears to not support these.

As per this question https://groups.google.com/forum/?fromgroups#!topic/spark-dev/eyIFm6mnBcE

I had success in a trivially simple async test case using spark as source off github and the MVC4 RC. What actually needs doing besides rebuilt with MVC4 and .net 4.5?

[AnthonySteele]

Async controller action handling appears to happen in System.Web.Mvc.Async.AsyncControllerActionInvoker
Is the view engine involved in this at all?

[RobertTheGrey]

To answer your first question, I think the C# compiler for rendering views dynamically is defaulted to 4.0, so that would need to be updated.

Second question, I don't know if the view engine is involved at that stage. I'm on family vacation at the moment, so I haven't had time to look at this in detail yet.

+1 on this feature

@maxild since you're working on MVC4 support - maybe you want to look at this requirement if you have time?

Thanks,
Rob

It may just work when spark is compiled in .Net 4.5 with MVC 4. I.e. if there are no complications, by the time the view engine is called, it may be that the async waiting for the controller action method to complete is all over and done and the Task's result has been upacked.

Ok, 4.5 is coming soon to nuget - it's already done on the repo, just need to release the nuget in 4.5 as well for someone to test this

[RobertTheGrey]

A specific Mvc4 v4.5 has been released in the latest Nuget package. Perhaps this can be tested as well?

How can i possibly cancel an ongoing $.ajax request to action and start a new one. I am talking about cancelling the request on the server as well not just client side. Async controllers offer an approach but its not feasible with my requirement, as the controller contains many synchronous actions which are causing a delay on response. How can we handle the aborting of request on the server?

It would be better to ask this kind of question on StackOverflow

I'm closing down this story. Spark works with async Task in ASP.NET 5.
