[Mono-dev] ASP.NET 4.5 Async Pipeline

[Martin Thwaites]

That's great,  there's only a few bits that need doing to make it compile,
and I'm pretty sure I can handle those.

I've put in some crude implementations of the missing elements to try and
scope the work involved, and unless there's something wrong in those, it
needs some further work under the hood.

The issue I see us that I'm getting never ending calls to Webapi endpoints,
whereas standard (non-async) MVC controllers work fine.

So my perception is that there is something stopping the pipeline from
completing.

I think the best option is to complete the missing elements that I believe
I can do, then possibly post a simple Webapi solution that reproduces it.
Then maybe you could use some of your (obviously large amount of) free time
to have a quick look.  Unless there is something off the top of your head
that you think I could look at?

On a side note, do you think you'll be going to Future Decoded on the 12th?
There's a possibility I might be going and it would be nice to put a face
to the name.

Thanks
Martin
Hey,

The changes should be done in Mono.   Just enough to have aspnetwebstack
compile out of the box.
