Hi there. I'm having a big problem when calling a web service from my WPF application. The application/window locks until the process has completed.

I have an ASP.NET page that needs to make calls to multiple web services to return data. I'd like to run these requests in parallel, and using the PageAsyncTask class appears to be the most appropriate way to do that. The trick is that there are five calls--say A, B, C, D, and E. Calls A & B must be made sequentially, as must C & D. The ...

If I click the back button on the navigation bar, it will only respond after the content of the table finish loading. Is there an easy way to load the content asynchronously so that the app wil...
The strength of Twisted (for python) is its asynchronous framework (I think). I've written an image processing server that takes requests via Perspective Broker. It works great as long as I feed it less than a couple hundred images at a time. However, sometimes it gets spiked with hundreds of images at virtually the same time. Because it...

We have a web application that takes file uploads for some parts. The file uploads aren't terribly big (mostly word documents and such), but they're much larger than your typical web request and they tend to tie up our threaded servers (zope 2 servers running behind an Apache proxy). I'm mostly in the brainstorming phase right now and...
I've been playing around with the Reactive Extension for a little while now, but mostly limited to handling/composing user driven events within a WPF frontend. It's such a powerful, new way of doing async programming, and I'm curious as to what other people are doing with it, and where do you think it might be able to improve the way we...
