I read some articles in MSDN magazine about new features in ASP.NET AJAX 4.0 - primarily client side data binding. I feel MSDN magazine sometimes contains a lot of "marketing" so I'm interested in opinions of real developers. Does it worth it? Do you plan to use it? Edit: Here are links for articles if anybody is interested. But at th...
I'm .NET developer. Most of my career I worked on web based intranet applications (ASP.NET WebForms) but always as a server side developer.

At the moment I have some JavaScript skills and very elementary understanding of both ASP.NET...

When Windows loads an NGend file, it checks to see if the file loads at its preferred base address. If the file cant load at its pre...

I'm in the market for an ASP.NET host to start learning on and to host personal projects. I've noticed most of them provided both MySQL and MS SQL databases. However, usually they will only provided a couple MS SQL databases, but a large number (like 10) MySQL Databases. Can I use a MySQL database as a back end to a ASP.NET website? If ...

I'm sure that this question has already been asked, but I don't really see it. Using asp.net and c#, how does one track the pages that are open/closed? I have tried all sorts of things, including: modifying the global.asax file application/session start/end operations setting a page's destructor to report back to the application ...
Is it possible to say something to the effect of 'SomeClass.Out.WriteLine("hello world")' and have it actually show up for the browser to render?

I'm curious as to whether or not these controls work well with modern browsers, or if they're basically IE only. I know it says it will render to "downleve...

When a user logs out the session is ended with: Session.Clear() Session.RemoveAll() Session.Abandon() I assumed that StateServer would then release some memory, but it will actually consume a bit more. In web.config I have the timeout set to 20 minutes. The sessi...
