Does ASP.NET MVC Framework support asynchronous page execution?

Question

I'm learning ASP.NET MVC Framework, From some articles like this, it seems that MvcHandler has only Execute() implemented, there is no asynchronous API implemented. Actually, I don't think Controller has asynchronous API either.

So, ASP.NET MVC doesn't support asynchronous programming? this could be a big hurdle to scalability if the web page needs I/O operation.

Answer 1

At the moment, async support is not built into MVC. It's on the feature list, but no guarantees as to exactly when it might be released (and in what form).

Answer 2

After some googling, I found this terrific blog about how to DIY asynchronous ASP.NET MVC. The implementation looks easy and straightforward. I am wondering why ASP.NET MVC team doesn't have this feature at the first time.

Answer 3

As Brad mentioned, Microsoft is working on a solution as part of MVC futures. There is also an implementation at: http://code.msdn.microsoft.com/AsyncMvc/Wiki/View.aspx?id=11350

Answer 4

ASP.NET MVC 2 has now incorporated asnyc controller from the beat release. Check it out.

Answer 5
